Chapter V: Part 5

The popularity of this cool and delicious fruit has in recent years been greatly enhanced by increased knowledge as to the best method of treating the plant, and also by the introduction of several varieties which are attractive in form and superb in flavour. It would shock a modern Melon eater to be advised to cook a Melon, and flavour it with vinegar and salt, as in the early days of English gardening. A good Melon of the present day does not even need the addition of sugar; the beauty, aroma, and flavour are such that it is not unusual for the epicure to push the luscious Pine aside in order to enjoy this cool, fresh, gratifying fruit that delights without cloying the palate. The newer varieties are remarkable alike for fruitfulness and high quality, and are somewhat hardier than the favourites of years gone by.

The Melon is grown in much the same way as the Cucumber, but it differs in requiring a firmer soil, a higher temperature, a much stronger light, less water, and more air. It may be said that no man should attempt to grow Melons until he has had some experience in growing Cucumbers. As regards this point, the hard and fast line is useless, but Cucumber-growing is certainly a good practical preparative for the higher walk wherein the Melon is found. But Cucumbers are grown advantageously all the winter through; Melons are not. The former are eaten green, and the latter are eaten ripe; this makes all the difference. Melons that are ripened between October and May are seldom worth the trouble bestowed upon them; therefore we shall say nothing about growing Melons in winter.

The Frame Culture may with advantage begin about the middle of March by the preparation of a good hot-bed. It is best to use a three-light frame, as the heat will be more constant than with one of smaller size. There should be six loads of stuff laid up for the bed, and the turning should be sufficient to take out the fire, without materially reducing the fermenting power. Begin a fortnight in advance of making up the bed, and be careful at every stage to do things well, as advised for the cultivation of frame Cucumbers. The best soil for Melons is a firm, turfy loam, nine inches of which should be placed on top of the manure. In a clay district, a certain amount of clay, disintegrated by frost, may be chopped over with turfy loam from an old pasture. If the soil is poor, decayed manure should be added, but the best possible Melons may be grown in a fertile loam without the aid of manures or stimulants of any kind. It is good practice to raise the plants in pots, and have them strong enough to plant out as soon as the newly-made beds have settled down to a steady temperature of about 80°, but below 70° will be unsafe. If plants cannot be prepared in advance, seed must be sown on the bed, and as a precaution against accidents and to permit of the removal of those which show any sign of weakness, a sufficient number of seeds should be sown to provide for contingencies.

As regards the bed, it may be made once and for all at the time of planting, a few days being allowed for warming the soil through. But we much prefer to begin with smallish hillocks, or with a thin sharp ridge raised so as almost to touch the lights, and to plant or sow on this ridge, which can be added to from time to time as the plants require more root room. The soil, coming fresh and fresh, sustains a vigorous and healthy root action. The high ridge favours the production of stout leaves, and the absorption by the soil of sun-heat is to the Melon of the first importance.

The practice of pruning Melons as if the plants were grown for fodder, and might be chopped at for supplies of herbage, must be heartily condemned. Melons should never be so crowded as to necessitate cutting out, except in a quite trivial manner. A free and vigorous plant is needed, and under skilful attention it will rarely happen that there is a single leaf anywhere that can be spared. We will propose a practical rule that we have followed in growing Melons for seed, of which a large crop of the most perfect fruits is absolutely needful to insure a fair return. The young plants are pinched when there are two rough leaves. The result is two side shoots. These are allowed to produce six or seven leaves, and are then pinched. After this, the plants are permitted to run, and there is no more pinching or pruning until the crop is visible. Then the fruits that are to remain must be selected, and the shoots be pinched to one eye above each fruit, and only one fruit should remain on a shoot; the others must be removed a few at a time. All overgrowth must be guarded against, for crowded plants will be comparatively worthless. It is not by rudely cutting out that crowding is to be prevented, but by timely pinching out every shoot that is likely to prove superfluous. From first to last there must be a regular plant, and not a shoot should be allowed to grow that is not wanted. Cutting out may produce canker, and crowding results in sterility.

As the Melon is required to ripen its fruits, and the Cucumber is not, the treatment varies in view of this difference. It is not necessary to fertilise the female flowers of the Cucumber, but it is certainly desirable, if not absolutely necessary, to operate on those of the Melon to insure a crop. The early morning, when the leaves are dry and the sun is shining, is the proper time for this task, which is described in a later paragraph. And the necessity for ripening the crop marks another difference of management, for Cucumbers may carry many fruits, and continue producing them until the plants are exhausted. But the production of Melons must be limited to about half a dozen on each plant, and good management requires that these should all ripen at the same time, or nearly so, fully exposed to the sun, and with plenty of ventilation.

The requisite supply of water is an important matter. The plant should never be dry at the root, and must have a light shower twice a day over the leafage, but the moisture which is necessary for Cucumbers would be excessive for Melons. It is a golden rule to grow Melons liberally, keeping them sturdy by judicious air-giving, and to give them a little extra watering just as they are coming into flower. Then, as the flowers open, the watering at the root should be discontinued, and the syringe should be used in the evening only at shutting up. If discontinued entirely, red spider will appear, and the crop will be in jeopardy, for that pest can be kept at a distance only by careful regulation of atmospheric moisture.

Melons in frames do better spread out on the beds than when trained on trellises. When so grown, each fruit must be supported with a flat tile or an inverted flower-pot, and means must be taken, by pegs or otherwise, to prevent it from rolling off, for the twist of stem that ensues may check the fruit or cause it to fall. When the fruits are as large as the top joint of a man’s thumb, watering may be resumed, and the syringe used twice a day until the fruit begins to change colour, when there must be a return to the dry system, but with care to avoid carrying it to a dangerous extreme.

The Melon-house, heated by hot water, is adapted to supply fruit earlier than is obtainable by frame culture, and is entirely superior to any frame or pit. It appears, however, that in Melon-houses red spider is more frequently seen than in frames heated by fermenting material; but this point rests on management, and there can be nothing more certain than that a reasonable employment of atmospheric humidity may be made effectual for preventing and removing this pest. For the convenient cultivation of the crop a lean-to or half-span is to be preferred. The width should not exceed twelve feet, and ten to twelve feet should be the utmost height of the roof. A service of pipes under the bed will be required; but as Melons are not grown in winter, the heating of a Melon-house is a simple affair, and, indeed, very much of the cultivation as the summer advances will be carried on by the aid of sun-heat only. The treatment of the plants in a house differs from the frame management, because a trellis is employed, and the plants are taken up the trellis without stopping until they nearly reach the top, when the points are pinched out to promote the growth of side shoots. In setting the fruit, the same principles prevail as in frame culture, and it is advisable to ‘set’ the whole crop at once; if two or three fruits obtain a good start, others that are set later will drop off. As the fruits swell, support must be afforded to prevent any undue strain on the vine, and this should be accomplished by nets specially made for the purpose, or by suspending small flat boards of half-inch deal with copper wires, each fruit resting on its board, until the cracking round the stem gives warning that the fruit should be cut and placed in the fruit room for a few days to complete the ripening for the table. In houses of the kind described Melons and Cucumbers are occasionally grown together. But although this may be done, and there are many cultivators expert in the business, the practice cannot be recommended, for ships that sail near the wind will come to grief some day. The moisture and partial shade that suit the Cucumber do not suit the Melon, and it is a poor compromise to make one end of the house shady and moist, and the other end sunny and dry, to establish different conditions with one atmosphere. A glass partition pretty well disposes of the difficulty, because it is then possible to insure two atmospheres suitable for two different operations. (_See also pages 157, 175, and 184._)

The Pollination of Melons is performed by plucking the mature male blooms, and after the removal of the petals, transferring the pollen of the male flower to the stigma of the female flower.

MERCURY

Chenopodium Bonus-Henricus

This perfectly hardy vegetable, known also by the name of Good King Henry, is much grown in Lincolnshire. The leaves are used in the same way as Spinach, and by earthing up the shoots they may be blanched as a substitute for Asparagus. Sow the seeds during April in drills twelve inches apart, and in due course thin the seedlings to one foot apart in the rows.

MUSHROOM

Agaricus campestris

The Mushroom has many friends among all classes, few benevolent neutrals, and fewer still who are absolutely hostile to it as an article of food. Those who find, or imagine they find, that this delicacy does not agree with them, might possibly arrive at another conclusion were a different mode of preparation adopted, or were the consumption of it accompanied with a full persuasion that the Mushroom is not merely delicious in flavour, but thoroughly wholesome, rich in flesh-forming constituents, and, for a vegetable, possessed of more than the average proportion of fat-formers and minerals. These facts have been clearly established by chemical analysis, and may dispose of timid misgivings, always supposing the true edible Mushroom, _Agaricus campestris_, to be in question.

Hitherto the artificial production of Mushrooms has never been equal to the demand. Notwithstanding the enormous quantities sent to Covent Garden by the growers around London, many tons are imported from France, although it is generally admitted that they are neither so fine nor so rich in flavour as those produced in this country. If, however, the large centres of population are inadequately supplied, the scarcity of Mushrooms is more keenly felt in the provinces, except, perhaps, in certain favoured districts, where, after a few warm days in autumn, an abundant crop may be gathered from the neighbouring pastures. Then there is a brave show in the greengrocers’ windows for a brief period, followed by entire dearth for weeks, and perhaps months. Obviously, therefore, the demand, large as it already is, might be immensely augmented by a commensurate supply. Yet it is not only possible but quite easy to grow Mushrooms for the greater part of the year in very small gardens, even when such gardens are entirely destitute of the appliances usually considered necessary for the higher flights of horticulture. The idea that Mushroom-growing is somewhat of a mystery, forbidden to all but the strictly initiated, has happily been dispelled. If we examine the conditions under which Mushrooms grow freely in pastures, it is surprising how few and simple are the elements of success. The crop generally appears in September, when temperature is genial and fairly equable, with sufficient but not superabundant moisture. The artificial production of Mushrooms in the garden needs only reliable spawn, a sweet fertile bed, and some means of maintaining a steady temperature under varying atmospheric conditions. When the principles of Mushroom culture are thoroughly mastered, they may be successfully applied in many different ways, and they render the practical work easy and tolerably certain.

The Spawn.—Although the Mushroom may be grown from seed, it is seldom done except for strictly scientific purposes. The seeds are, however, largely disseminated by Nature, and, having found a suitable home, they germinate and produce an underground growth which at a hasty glance resembles mildew. It really consists of white gossamer-like films, which increase in number and distinctness as they develop, until they push their way towards the surface, and give rise to the growth above ground of the Mushroom. It follows that if we do not begin the cultivation with seeds or spores, we must resort to the white films or ‘mycelium,’ that the growth of the plant may begin in Nature’s own way below ground. What is called ‘Mushroom Spawn’ consists of certain materials from the stable and the field, mixed and prepared in such a manner as to favour the development of the mycelium of the Mushroom. When dried, the cakes have the appearance of an unburnt brick. The preparation of the spawn, though a very simple matter, demands the skill and care of experienced operators. If the work is not well done, the spawn will be of poor quality, and will yield a meagre crop, or perhaps fail to produce a single Mushroom. Whether the cakes or bricks are impregnated in the manner long practised in this country, or direct from the tissue of the Mushroom, the culture remains the same. Provided that the spawn is good, it has but to be broken into lumps of a suitable size, and inserted in the bed, to impregnate the entire mass with the necessary white films. These will take their time to collect from the soil the alkalies and phosphates of which Mushrooms principally consist, and this part of their work being done, the fruits of their labours will be displayed above ground in the elegant and sweet-smelling fungus that few human appetites can resist when it is placed upon the table in the way that it deserves. Experts can readily form an opinion as to whether a cake of Mushroom spawn is or is not in a fit state for planting, and it will be a safe proceeding for the amateur to buy from a Firm which has a large and constant sale; otherwise, spawn may be purchased which was originally well made and properly impregnated, but has lost its vitality through long keeping.

Soil.—As to soil, it is well known that in a favourable autumn Mushrooms abound in old rich pastures, and those who have command of turf cut from a field of this character have only to stack the sods grass side downwards for a year or two, and they will be in possession of first-class material for Mushroom beds either in the open or under cover. But small gardens, particularly in towns, have no such bank to honour their drafts, and for these it becomes a question of buying a load or two of turfy loam, or of making the soil of the garden answer, perhaps with a preliminary enrichment by artificial manure. In the general interests of the garden, the money for a limited quantity of good loam would probably be well spent, independently of the question of Mushrooms. No great bulk is necessary to cover a moderate-sized Mushroom bed, but the quality of the soil will certainly have an influence on the number and character of the Mushrooms. As a proof of the exhaustive nature of the fungus, it almost invariably happens that when the soil is used a second time it tends to diminish the size and lower the quality of the crop.

Manure.—In the management of the manure two essentials must be borne in mind. Not only is nourishment for the plant required, but warmth also. Probably a large proportion of the failures to grow Mushrooms might, if all the facts were known, be traced to some defect in the manure employed, or to some fault in its preparation. It must be rich in the properties which encourage and support the development of Mushrooms, absolutely free from the least objectionable odour, for the plant is most fastidious in its demand for sweetness, although it can dispense with light; and there must remain in the manure when made into a bed a sufficient reserve of fermentation to insure prolonged heat, no matter what the temperature of the atmosphere may be. Of course, the duration of the heat will depend very much on the care with which it is conserved by suitable covering and management. These requirements, formidable as they may seem, can be insured with extreme ease; indeed, the work is apparently far more difficult and complicated on paper than it proves to be in practice.

Preparation of the Bed.—The manure should come from stables occupied by horses in good health, fed exclusively on hard food. The most suitable store is the floor of a dry shed, or under some protection which will prevent the loss of vital forces. Ammonia, for example, is readily dissipated in the atmosphere or washed away by rain. The manure should neither be allowed to become dust dry, nor to waste its power in premature fermentation. Operations may be commenced with three or four loads. A smaller quantity increases the difficulty of maintaining the requisite temperature when fermentation begins to flag. The first procedure is to make the manure into a high oblong heap well trodden down. If the stuff be somewhat dry, a sprinkling of water over every layer will be necessary. In a few days fermentation will make the heap hot all through, and then it must be taken to pieces and remade, putting all the outside portions into the interior, with the object of insuring equal fermentation of the entire bulk. This process will have to be repeated several times at intervals of three or four days until the manure has not only been fermented but sweetened. When ready it will be of a dark colour, soft, damp enough to be cohesive under pressure, but not sufficiently damp to part with any of its moisture, and almost odourless; at all events the odour will not be objectionable, but may be suggestive of Mushrooms. Make a long bed, having a base about four feet wide, and sides sloping to a ridge like the roof of a house, with this difference—the narrow part of the ridge is useless, and the top should, therefore, be rounded off when about a foot across. Some growers prefer a circular bed of six or eight feet diameter at the bottom and tapering towards a point, after the shape of a military tent; but here again the point will be worthless, and the bed may terminate abruptly. Either the long bed or the round heap answers admirably. Tread the manure down compactly, and for the sake of appearances endeavour to finish it off in a workmanlike manner. During the first few days there will be a considerable rise in the temperature, which will gradually subside, and when the plunging thermometer shows that it has settled down to a comfortable condition of about 80° the bed must be spawned. Experienced men can determine by the sense of touch when the temperature is right, but the inexperienced should rely entirely on the thermometer. The question will arise as to the period of the year when operations should be commenced. Well, the experts who grow Mushrooms in the open ground for market gather crops almost the year round; but a beginner will do wisely to start under the most favourable natural conditions, and these will be found about midsummer, because the bed will commence bearing before winter creates difficulty as to temperature.

Spawning and After-management.—Break each cake of spawn into eight or ten pieces, and force every piece gently a little way into the manure at regular intervals of six to nine inches all over the bed, closing the manure over and round each piece of spawn. The practice of inserting spawn by means of the dibber is to be strongly condemned, for it leaves smooth, hollow spaces which arrest the mycelium; and very small pieces of spawn should be avoided because they generally result in small Mushrooms. Immediately the spawning is completed, a thick and even covering of clean straw or litter of some kind should be laid over the bed, secured from wind by canvas, mats, hurdles, or in some other way. From good spawn the films of mycelium will begin to extend within a week. In the contrary case an examination of the pieces will show that they have become darker than when put into the bed, which means that they have perished. Then the question will arise as to whether the bed or the spawn is at fault, and the former must either be spawned again or broken up. Supposing the spawn to show signs of vitality, the time has come for covering the bed with a layer of rather moist soil, pressed lightly but firmly on to the manure with the spade or fork, so that the earth will not slip down. At once restore the covering of litter, &c., and wait patiently for about seven or eight weeks for the crop. Meanwhile the plunging thermometer ought to be consulted daily. Until the Mushrooms appear the instrument should not indicate less than 60°, and while in bearing not less than 55°. Experience proves that the most violent alternations of temperature may be combated by regulating the thickness of the covering. Although it may possibly be necessary to resort to eighteen inches of litter or more during hard frost or the prevalence of a cutting east wind, a much thinner covering will suffice in milder weather.

Should the temperature of the bed, through inexperience in the management of it, sink below the point at which Mushrooms can grow, we advise the exercise of a little patience. We have known several instances of beds made in autumn producing no crop at the expected time, but which have borne fairly in the following spring or summer. But in the event of the first effort failing outright there is no great loss. The manure, which is the most costly item, will still be available for the garden, and an observant man will pretty well understand in what respect he must amend his course of procedure.

Water.—Moisture is of great consequence, for a dry Mushroom bed will soon be barren also; but whenever water is given it must be applied tepid and from a fine rose. To slop cold water over a Mushroom bed is about as reasonable a procedure as putting ice into hot soup. Water is best administered in the afternoon of a genial day, and should be sufficient to saturate the bed. Immediately it is done the covering of litter and canvas must be promptly restored to prevent the temperature from being seriously lowered by rapid evaporation. A couple of stakes driven from the crown to the bottom of the bed at the time of making up the heap are useful as indicators of moisture, and may occasionally be drawn out and examined.

In gathering the crop, only a small portion of the bed should be uncovered at a time. This should be the rule at all seasons, and the strict observance of it will prevent a mistake in cold weather, for then, if the bed is carelessly uncovered and much chilled, the crop will come to an end, when perhaps it would, if properly handled, be at high tide and full of profit. Another rule should be enforced, to this effect, that every Mushroom must be taken out complete, and if the root does not come with the stem, it must be dug out with a knife. Any trifling with this rule will prove a costly mistake. The stem of a Mushroom, if left in the ground, will produce nothing at all. But it may attract flies, and it certainly will interfere with the movements of the mycelium at that particular spot, and actually prevent the production of any more Mushrooms. The old practitioners were accustomed to leave the stem in the ground, and they were content with about one-third of the crop now produced on beds that are, perhaps, not better made than were theirs. But they had a notion about the powers of the root which increased knowledge of the subject has shown to be fallacious.

In Pastures.—As already indicated, Mushrooms are often to be found in abundance in well-stocked pastures during the late summer months, and where favourable conditions exist it is an excellent plan to insert pieces of spawn two inches deep in the turf in June and July.

Turf Pits.—The facility with which Mushrooms may be raised under simple methods is illustrated by the practice of growing them inside the turf walls of cool pits. In the country turf walls are common, and they offer the advantage of growing Mushrooms in addition to the purpose they usually serve. After determining the size of the pit, and accurately marking it on the ground, cut the turf into narrow strips, say three or four inches wide, and of exactly eighteen inches length. The strips should be closely laid, grass side downwards, across the width of the walls—not longitudinally—except at the corners, where the layers should cross each other. The front and back walls to be rather above the required height, because the turf always scales down a little, and the two ends must gradually rise from front to back. The top layer may be right side up, when it will keep green for a long time. As the work proceeds insert lumps of spawn at intervals in every layer, about three or four inches from the inside edge. A wooden frame will be requisite on the top to carry the glass lights. This structure makes a useful cool pit and a Mushroom bed from which supplies may sometimes be gathered for years. In the summer it will be necessary to keep the walls moist by means of the syringe, or they will cease bearing.

Indoor Beds.—Mushrooms may be grown almost anywhere, evenly in a cellar, or on the wall of a warm stable, provided only that the mode of procedure is in a reasonable degree adapted to the requirements of the fungus. Ordinary pits and frames are also serviceable, and many gardeners obtain good crops in autumn by the simple process of inserting a few lumps of spawn in a Cucumber or Melon bed while the plants are still in bearing. Between spawning and cropping a period of six or eight weeks usually elapses, so that if the plan just mentioned be adopted, the spawn should be introduced in the height of summer, both to insure it a warm bed and to allow time for the crop to mature before the season runs out. Sheds and outhouses not only afford shelter and space for beds on the floor, but the walls can be fitted with shelves on which Mushrooms may be plentifully grown. In all cases the shelves should be two feet apart vertically, and each shelf should have a ledge nine inches deep. The walls of a house may be quickly and cheaply fitted with woodwork for the purpose, but brick is so much better than wood that whenever it is possible to employ brick it should have the preference. As regards the ledges, they should be of stout planking in any case, and should not be fixed, because of the necessity for clearing the shelves and renewing the soil periodically. The details of cultivation are the same within doors as without, but the roof gives valuable protection, and helps to maintain the beds at a suitable temperature.

A proper Mushroom-house for production during winter should be heated with hot water, and have an opaque roof. There is nothing so good for the crop as a roof of thatch, but there are many objections to it, and usually slate is employed. A double roof will pay for its extra cost by promoting an equable temperature. A few side lights fitted with shutters are necessary, as there should be a good light for working purposes; but the crop does not need light, and a more steady temperature can be maintained in a dark house than in one which has several windows. The most convenient dimensions for a Mushroom-house are: length, twenty-five feet; width, twelve feet; height at sides, six feet, to allow of a bed on the floor, and a shelf four feet above it; the ridge rising sufficiently for head room, and to shoot off water. There will be room for a central path of four feet, and a bed of four feet on each side. An earth or tile floor and a slate or stone shelf will, with one four-inch flow and return pipe, complete the arrangements. The less wood and the less concrete the better; there is nothing like porous red tiles for the floor and stone for the shelves, with loose planks on edge to keep up the soil, a few uprights being sufficient to hold them in their places.

Temperatures at every point are of great importance. The bed should be near 80° when the spawn is inserted. The air temperature requisite to the rising crop is 60° to 65°, which is the usual temperature of the season when Mushrooms appear in pastures. While the bed is bearing a temperature of 55° will suffice, but at any point below this minimum production will be slow and may come to a stop. When giving water, take care that it is at a temperature rather above than below that of the bed.

MUSTARD

Sinapis alba, and S. nigra

Mustard is much valued as a pungent salad, and for mixing in the bowl it may take the place of Water Cress when the latter is not at command. Mustard is often sown with Cress, but it is bad practice, for the two plants do not grow at the same pace, and there is nothing gained by mixing them. The proper sort for salading is the common White Mustard, but Brown Mustard may be used for the purpose. Rape is employed for market work, but should be shunned in the garden. As the crop is cut in the seed leaf, it is necessary to sow often, but the frequency must be regulated by the demand. Supplies may be kept up through the winter by sowing in shallow boxes, which can be put into vineries, forcing pits, and other odd places. Boxes answer admirably, as they can be placed on the pipes if needful; they favour the complete cutting of a crop without remainders, and this is of importance in the case of a salad that runs out of use quickly and is so easily produced. From Lady Day to Michaelmas Mustard may be sown on the open border with other saladings, but as the summer advances a shady place must be found for it.

ONION

Allium Cepa

The onion has the good fortune to be generally appreciated and well grown almost everywhere. It enhances the flavour and digestibility of many important articles of food that would fail to nourish us without its aid, while to others it adds a zest that contributes alike to enjoyment and health. Although there are but few difficulties to be encountered in the cultivation of the Onion, there is a marked difference between a well-grown crop and one under poor management. There is, moreover, what may be termed a fine art department in Onion culture, one result being special exhibitions, in which handsome bulbs of great weight are brought forward in competition for the amusement and edification of the sight-seeing public. Thus, when the first principles have been mastered, there may be, for the earnest cultivator of this useful root, many more things to be learned, and that may be worth learning, alike for their interest and utility.

Treatment of Soil.—The Onion can be grown on any kind of soil, but poor land must be assisted by liberal manuring. A soil that will not produce large Onions may produce small ones, and the smallest are acceptable when no others are to be had. But for handsome bulbs and a heavy crop a deep rich loam of a somewhat light texture is required, although an adhesive loam, or even a clay, may be improved for the purpose; while on a sandy soil excellent results may be obtained by good management, especially in a wet season. In any case the soil must be well prepared by deep digging, breaking the lumps, and laying up in ridges to be disintegrated by the weather, and if needful its texture should be amended, as far as possible, at the same time. A coat of clay may be spread over a piece of sand, to be thoroughly incorporated with it; on the other hand, where the staple is clay, the addition of sand will be advantageous. All such corrective measures yield an adequate return if prudently carried out, because it is possible to grow Onions from year to year on the same ground; and thus in places where the soil is decidedly unsuitable a plot may be specially prepared for Onions, and if the first crop does not fully pay the cost, those that follow will do so. But the plant is not fastidious, and it is easy work almost anywhere to grow useful Onions. The first step in preparing land is to make it loose and fine throughout, and as far as possible to do this some time before the seed is sown. For sowing in spring, the beds should be prepared in the rough before winter, and when the time comes for levelling down and finishing, the top crust will be found well pulverised, and in a kindly state to receive the seed. Stagnant moisture is deadly to Onions, therefore swampy ground is most unfit; but a sufficient degree of dryness for a summer crop may often be secured by trenching, and leaving rather deep alleys between the beds to carry off surface water during heavy rains.

Manures.—As almost any soil will suit the Onion, so also will almost any kind of manure, provided that it be not rank or offensive. This strongly flavoured plant likes good but sweet living, and it is sheer folly to load the ground for it with coarse and stimulating manures. Yet it is often done, and the result is a stiff-necked generation of bulbs that refuse to ripen, or there may be complete failure of the crop through disease or plethora. But any fertiliser that is at hand, whether from the pigstye, or the sweepings of poultry yards or pigeon lofts, may be turned to account by the simple process of first making it into a compost with fresh soil, and then digging it in some time in advance of the season for sowing, and in reasonable but not excessive quantity. All such aids to plant growth as guano, charcoal, and well-rotted farmyard manure, may be used advantageously for the Onion crop; but there are two materials of especial value, and costing least of any, that are universally employed by large growers, both to help the growth and prevent maggot and canker. These are lime and soot, which are sown together when the ground is finally prepared for the seed, and in quantity only sufficient to colour the ground. They exercise a magical influence, and those who make money by growing Onions take care to employ them as a necessary part of their business routine.

Spring-sown Onions require to be put on rich, mellow ground, the top spit of which is of a somewhat fine texture, and at the time of sowing almost dry. Having been well dug and manured in good time, the top spit only should be dug over when it is finally made ready for the seed. The work must be done with care, and the beds should be marked off in breadths of four feet, with one-foot alleys between. Break all lumps with the spade, and work the surface to a regular and finely crumbled texture. Light soil should be trodden over to consolidate it, and then the surface may be carefully touched with the rake to prepare it for the seed. March and April are the usual months for spring sowing, although in mild districts seed is sometimes put in as early as January. Space the rows from nine to twelve inches apart, according to the character of the sort and the size of bulbs required. The drills must be drawn across the bed, at right angles to the alleys, for when drawn the other way it is difficult to keep the ground properly weeded. For a crop of Onions intended for storing, the seed should be only just covered with fine earth taken from the alleys and thrown over, after which the drills must be lightly trodden, the surface again touched over with the rake, and if the soil is dry and works nicely, the business may be finished by gently patting the bed all over with the back of the spade. If the ground is damp or heavy, this final touch may be omitted, as the Onion makes a weak grass that cannot easily push through earth that is caked over it. But speaking generally, an Onion bed newly sown should be quite smooth as if finished with a roller. To the beginner this will appear a protracted and complicated story, but the expert will attest that Onions require and will abundantly pay for special management.

As soon as possible after the crop is visible the ground between should be delicately chopped over with the hoe to check the weeds that will then be rising. Immediately the rows are defined a first thinning should be made with a small hoe, care being taken to leave a good plant on the ground. The next thinning will produce young Onions for saladings, and this kind of thinning may be continued by removing plants equally all over the bed to insure an even crop, the final distance for bulbing being about six inches. Keep the hoe at work, for if weeds are allowed to make way, the crop will be seriously injured. When Onions are doing well they lift themselves up and _sit_ on the earth, needing light and air upon their bulbs to the very axis whence the roots diverge. If weeds spread amongst them the bulbs are robbed of air and light, and their keeping properties are impaired. But in the use of the hoe it is important not to loosen the ground or to draw any earth towards the bulbs. When all the thinning has been done, and the weeds are kept down, it will perhaps be observed that in places there are clusters of bulbs fighting for a place and rising out of the ground together as though enjoying the conflict. With almost any other kind of plant this crowding would bode mischief, but with Onions it is not so. Bulbs that grow in crowds and rise out of the ground will never be so large as those that have plenty of room, but they will be of excellent quality, and will keep better than any that have had ample space for high development. It is almost a pity to touch these accidental clusters, for the removal of a portion will perhaps loosen the ground, and so spoil the character of those that are left. Really fine Onions are rarely produced in loose ground, hence the necessity for care in the use of the hoe. Watering is not often needed, and we may go so far as to say that, in a general way, it is objectionable. But a long drought on light land may put the crop in jeopardy, unless watering is resorted to, in which case weak manure water will be beneficial. Still, watering must be discontinued in good time, or it will prevent the ripening of the bulbs, and if a sign is wanted the growth will afford it, for from the time the bulbs have attained to a reasonable size the water will do more harm than good.

The harvesting of the crop requires as much care as the growing of it. If all goes well, the bulbs will ripen naturally, and being drawn and dried on the ground for a few days with their roots looking southward, may be gathered up and topped and tailed or bunched as may be most convenient. But there may be a little hesitation of the plant in finishing growth, the result, perhaps, of cool moist weather, when dry hot weather would be better. In this case the growth may be checked by passing a rod (as the handle of a rake for example) over the bed to bend down the tops. After this the tops will turn yellow, and the necks will shrink, and advantage must be taken of fine weather to draw the Onions and lay them out to dry. A gravel path or a dry shed fully open to the sun will ripen them more completely than the bed on which they have been grown; but large breadths of Onions must be ripened where they grew, and experience teaches when they may be drawn with safety.

As to keeping Onions, any dry, cool, airy place will answer. But if a difficulty arises there is an easy way out of it, for Onions may be hung in bunches on an open wall under the shelter of the eaves of any building, and thus the outsides of barns and stables and cottages may be converted into Onion stores, leaving the inside free for things that are less able to take care of themselves. During severe frost they must be taken down and piled up anywhere in a safe place, but may be put on their hooks again when the weather softens, for a slight frost will not harm them in the least, and the wall will keep them comparatively warm and dry. When the best part of the crop has been bunched or roped, the remainder may be thrown into a heap in a cool dry shed, and a few mats put over them will prevent sprouting for at least three months. But damp will start them into growth, and the only way to save them then is to top and tail them again, and store as dry as possible in shallow baskets or boxes.

To grow large Onions the principles already explained must be carried into practice in a more intense degree. It will be necessary to devote extreme care to the preparation of the ground, and to give the plants more time to mature; much greater space must also be allowed than is usual for an ordinary crop. A good open position is imperative, and where the soil is sufficiently deep, trenching is desirable. Shallow soil ought to be thoroughly dug down to the last inch, and it will be an advantage to break up the subsoil by pickaxe and fork. Cover the subsoil with a thick layer of rotten manure before restoring the top soil. For light land farmyard manure is excellent, but stable manure is preferable for stiff cold soil. The usual time for trenching is October or November, leaving the surface rough for disintegration during winter. Nothing more need be done until the following March. Early in that month break the soil down to a fine tilth and make it quite firm by treading, or by rolling. Then broadcast over the plot a liberal dressing of ground lime and soot, using about three pounds of each per pole. Rake both in and leave the bed until the time arrives for planting out: this will depend on the weather.

Those who are accustomed to exhibit Onions at horticultural shows almost invariably sow very early in the year under glass and in due time transplant either from seed-pans or boxes. Of the two, properly prepared boxes are usually found most convenient. The dimensions are optional, but boxes about two feet long, one foot wide, and five inches deep answer admirably. Several holes are perforated in the bottom to insure efficient drainage. In every box place a thick layer of rotten manure and then fill with thoroughly rich soil firmly pressed down, leaving the surface quite smooth. One of the most successful growers sows seed in rather small boxes early in January, and about the middle of February the young Onions are pricked into boxes of the size we have named. Only the finest and most promising seedlings are used. When transferred, each Onion is allowed a space of three inches. The boxes are kept in a greenhouse, as near the glass as possible, in a temperature of about 50°. After sowing, very little water is given; but when transplanted, finish with a sprinkling from a fine rose. Every morning the plants will require spraying, but this must never be done at night or damping off may follow. All through their time in the greenhouse it is important to keep the boxes near the glass. Towards the end of March remove to cold frames, keeping the lights rather close for a few days, but gradually giving more air until the lights can be taken off for a short time daily.

In the south, about the middle of April is generally a suitable time for transplanting to open beds, but in the event of a cold east wind prevailing a brief delay is advisable and it is always an advantage to plant out on a dull day or in showery weather. Space the rows twelve to eighteen inches apart, and allow about fifteen inches between plants in the rows. In the actual work of transplanting take care to insert only the fibrous roots in the soil. To bury any portion of the stem results in thickened necks. Finish with a dusting of soot over the entire bed, including the Onions, and then well spray from a fine rose to settle the soil around the roots. Until the plants are established continue the spraying daily. After the middle of May renew the dusting of the bed with soot and repeat at fortnightly intervals. About the 20th of June feeding the Onions must commence. Peruvian guano and nitrate of soda are both excellent, but these powerful artificials need using with discretion, or the crop may be scorched instead of stimulated. It is often safer to employ them in liquid form than dry, and ten ounces of either, dissolved in ten gallons of water, will suffice for thirty square yards. Use the two articles alternately at intervals of ten days and cease at the end of July. If continued longer, some of the finest bulbs will split. The use of soot can, however, be regularly maintained. Should bulbs be required for autumn exhibition carefully lift them a week or ten days in advance of the show date. This has the effect of making the bulbs firm and reducing the size of the necks.

Supposing an attack of mildew to occur, a dusting of flowers of sulphur will prove effective if applied immediately the disease appears. Sulphide of potassium, one ounce to a gallon of water, is also a reliable remedy.

July and August Sowing.—During these months seed of the quick-growing types of Onion may be sown for producing an abundant supply of salading and small bulbs during the autumn and onwards. It is important to thin the plants early in order that those left standing in the rows may have every opportunity of developing rapidly.

Autumn-sown Onions, intended for use in the following summer, may also be sown in the same way as advised for spring sowing. The time of sowing is important, as the plants should be forward enough before winter to be useful, but not so forward as to be in danger of injury from severe frost. On well-drained ground all the sorts are hardy, and the finest types, which are so much prized as household and market Onions, may be sown in autumn as safely as any others. It may be well in most places to sow a small plot: in the latter part of July, and to make a large sowing of the best keeping sorts about the middle of August—say, for the far north the first of the month, and for the far south the very last day. Thin the plants in the rows and transplant the thinnings, if required, as soon as weather permits in February. In places where spring-sown Onions do not ripen in good time in consequence of cold wet weather, autumn sowing may prove advantageous, as the ripening will take place when the summer is at its best, and the crop may be taken off before the season breaks down.

Pickling Onions may be obtained by sowing any of the white or straw-coloured varieties that are grown for keeping, but the large sorts are quite unfit; the best are the Queen and Paris Silver-skin, as they are very white when pickled and are moderately mild in flavour. A piece of poor dry ground should be selected and made fine on the surface. Sow in the month of April thickly, but evenly, cover lightly, and roll or tread to give a firm seed-bed, and make a good finish. Be careful to keep down weeds, and do not thin the crop at all. If sown very shallow the bulbs will be round: if sown an inch deep they will be oval or pear-shaped.

The Potato or Underground Onion is not much grown in this country, in consequence of occasional losses of the crop in severe winters. In the South of England the rule as to growing it is to plant on the shortest day, and take up on the longest. It requires a rich, deep soil, and to be planted in rows twelve inches apart, the bulbs nine inches apart in the row. Some cultivators earth them up like Potatoes, but we prefer to let the bulbs rise into the light, even by the removal of the earth, so as to form a basin around each, taking care, of course, not to lay bare the roots in so doing. When the planted bulbs have put forth a good head of leaves, they form clusters of bulbs around them, and the best growth is made in full daylight, the bulbs sitting on and not in the soil.

The Onion Grub (_Phorbia cepetorum_) is often very troublesome to the crop, especially in its early stages, and its presence may be known by the grass becoming yellow and falling on the ground. It will then be found that the white portion, which should become the bulb, has been pierced to the centre by a fleshy, shining maggot, a quarter of an inch in length, this being the larva of an ashy-coloured, ill-looking, two-winged fly. Where this plague has acquired such a hold as to be a serious nuisance, care should be taken to clear out all the old store of Onions instantly upon a sufficiency of young Onions becoming available in spring, and to burn them without hesitation. If left to become garden waste in the usual way, these old Onions do much to perpetuate and augment the plague. A regular use of lime and soot will be found an effectual preventive.
