Chapter III: Part I: Fruit Growing (3)

It was fully demonstrated by experiment about 25 years ago that herbage under trees sprayed with paris green at the rate of 1 pound to 160 gallons of water was not injurious to animals pasturing upon it. We are not aware that such an experiment has been made with the more recently used arsenates - which can be used with a much higher amount of arsenic to the gallon because they do not injure the foliage - to determine whether the herbage below would be poisonous or not. Presumably not, because modern spraying does not admit as much loss from run-off as was the case with old Spraying methods.

Pears on Quince.

I saw some time ago a report of some French experiments in grafting the pear onto quince root. The report said the fruit produced was much larger than on any other root.

Most of our common pears will take readily when grafted on the quince, but the quince transforms them into dwarfed trees. Such trees do produce, with proper care, very fine fruit. The remark about their being better than on standard trees refers, however, to other climates than ours, for California grows just as large pears on standard trees as can possibly be grown, while where conditions are harder the higher culture of the dwarf tree and the protection which it requires from climatic hardships, gives the dwarf tree the advantage. You can get pears on quince roots from most of our California nurseries.

Pollination of Pears.

Is it necessary in growing the Comice pear successfully, to put some other pear near for the purpose of pollination in order to make it successful? Will the ordinary Bartlett pear do for pollination?

The Comice pear blooms with the Bartlett, and would therefore presumably be of pollinizing benefit to the Bartlett if the latter should require such treatment. Common experience in California, however, is that the Bartlett is self-fertile and not self-sterile as it is commonly reported in Eastern publications. California practice is, then, to plant Bartletts solidly without reference to preparation for pollination. Taking the matter the other way around, the Bartlett will do for pollination of the Comice probably, if that should be necessary.

Lye-Peeling Peaches.

Please give the formula for peeling peaches by dipping them in caustic soda or lye.

Lye for peeling peaches is used at the rate of half to one pound to the gallon of water, according to the strength of the lye, which you can determine by the quickness with which it acts. The lye water is kept boiling, and the fruit is dipped in wire baskets, only being allowed to remain in the lye a few seconds, and is then plunged at once into fresh water. You must be careful to keep the lye boiling hot, also either to use running water for rinsing or change it very frequently, for you have to rely on fresh water to remove the lye, or the fruit is likely to be stained.

Aged Peach Trees.

What should be done with peach trees 35 years old which are becoming unthrifty, bearing only at the ends of the limbs, etc.?

Old peach trees become bark-bound and need to be cut back to just above the crotch for the forcing out of new branches, this being facilitated, of course, by application of manure, good cultivation of the soil, use of water during the dry season, etc. The peach is, under most conditions, not a long-lived tree, and if your trees are 35 years of age, it is probable that best results could be obtained by grubbing them out and replanting with young trees on new soil if possible. The profitable life of the Eastern peach tree is put down at five or six years. In California the profitable life of the peach sometimes reaches twenty or more years, if growing under exceptionally good conditions; but 35 years would seem to be at least on the borders of decrepitude. Growing at the tips shows that you have not pruned annually to induce the growth of new wood lower down.

Renewing Peach Orchard.

Which is the best way to renew an old peach orchard? The trees are about 18 years old, Muirs and Fosters, and are yielding good crops, but some of the trees show decline. Is it best to replace the old ones with new trees or to plant a new orchard in between the old trees and cut out old ones when new trees are three or four years old?

If the trees have sound bodies and are not badly injured by sunburn borers, do none of the things you mention, but would cut back for a new head. Cutting back should be done during the latter half of the dormant period and thinning of shoots to proper balance a new head should be carefully done the following winter. It is a hard job to get young trees to start among old trees and you are apt to get a mixed lot of trees which you will not be proud of. Cut back as suggested or rip out, plow deeply and start anew, placing the rows midway between the old rows.

Will He Have Peaches?

I have a young orchard between five and six years old, mostly of the Lovell variety. I didn't have much of a crop this year. Should I have a good crop next year?

You ought to be able to tell now how full a set of fruit buds you have. If you do not know what the fruit buds are, ask some neighbor who knows peaches to point them out. If you have a good show of fruit buds, the question in California is not whether they will winter-kill or not, but whether the leaves held late enough the preceding summer and therefore the tree had strength enough to make good strong fruit buds. The late action of the leaves shows that the trees had enough autumn moisture. You will soon learn to recognize the condition also from the plumpness of the wood which carries the fruit buds. If all has gone well so far, the next point is to spray with the bordeaux mixture in November or December so that the new wood shall not be attacked by the peach blight or shothole fungus. This disease comes on early in the winter, sets the the new bark to gumming and endangers the crop. Then if you have San Jose scale, or if your trees showed much curl-leaf last spring, you ought to spray before the blossom buds show color with the lime-sulphur wash. Supposing that you have good buds now and are willing to protect them as suggested, your trees may be expected to come through with a good crop if seasonal moisture conditions are right.

Peach Fillers in Apple Orchard.

I have heard some talk against planting peach fillers in an apple orchard. What is your opinion on the subject?

There is no objection providing the peach is profitable in the locality; and that point you must look into. The peach trees will not injure the apples unless they are allowed to stand too long. In that case they would interfere with the development of the apple.

Grafting Peach on Almond.

May I expect to get good results by grafting some kind of peach to 19-year-old almond tree? If so, what kind of peach will be best? When shall I do grafting?

Peaches take to the almond all right. Cut off and graft in the branches above the main forking of the tree; leaving at least one large branch to be grafted later or to be cut out entirely if you have peach growth enough to fill the top sufficiently. Graft in any kind of peach you find to be worth growing. Graft toward the latter part of the dormant season, say when the buds are swelling for a new start.

Peaches on Apricot.

I have a three-year-old peach orchard grafted or budded on apricot roots, and interspersed through the orchard are young apricot trees, from half-inch to inch and a half in diameter, which sprang from the root, the peach bud or graft having died. I budded these over to peaches in summer, but the buds all died for some cause. What is now the best course to transform them into peach trees? If a graft, what form of graft, and approximately when should it be made?

You can graft peach scions into the apricot sprouts by taking the peach scions of the varieties you desire while the tree is perfectly dormant, keeping them in a cool place and putting in the grafts just as the buds are beginning to swell on the apricot stock. The scions can be buried in the earth in the shade of a fence or building, selecting a place, however, which is moist enough and yet where the water does not gather. The ordinary form of top grafting in stems an inch or more in diameter will work well. The half-inch stems can be whip-grafted successfully. You will have to wax well and see that the wax coating is kept sound until the growth starts.

Replanting After Root-knots.

In digging out some old peach trees, I find now and then a tree affected with root knot. I am burning the root, of course, but as these trees are scattered in the orchard, I wish to plant young trees in same locations, thus preserving the rows. Can new stock be safely put in the earth from which the old tree is removed? If treatment of the soil is essential, what is recommended?

Dig a good large hole, removing the earth, and fill with new earth from between the rows, and in this way healthy growth ought to be obtained, although there is always a disposition in some trees to put on knots. They should be looked at from time to time and all those affecting the larger stem should be removed and the wound painted with bordeaux mixture.

Buds in Bearing Trees.

In budding over some old peach trees, should I cut away the branch above the bud when the latter seems to have taken?

The sap flow to the upper part of the branch should be checked by part girdling or by part breaking or bending the top above the bud, after the bud is seen to have set or taken. Do not remove the whole top until the growth on the bud has started out well or else you will "drown it" with excessive sap flow.

Pollen Must Be of the Same Kind.

Do peaches, nectarines and apricots set fruit with the pollen of one another, and are the various peaches, nectarines and apricots self-sterile, or will most kinds set fruit with their own pollen?

We do not count upon pollination between different kinds of fruit. Most fruits are self-fertile, else we could not attain the practical results we do, because it is only in the planting of almonds, cherries, pears and apples that any regard is paid to the association of varieties for that cross-fertilization. Some fruits are more apt to be self-fertile in this State than in other States where the growing conditions are not so favorable.

Peach Budding.

Which is easier with the peach, grafting or budding?

The peach is rather a difficult tree to graft, and budding, on the other hand, is quite easy. You can bud into new shoots of this season's growth in July, and, if necessary, you can improve the slipping of the bark by irrigation a few days before budding. Buds can also be successfully placed in June in the old bark of the peach, providing it is not too old. For this select well-matured buds from the larger shoots and use rather a larger shield than in working into new shoots. When the buds are seen to have taken, the top growth beyond it can be reduced gradually and some new growth forced on the buds the same season, if the sap flow continues as it might be expected to do on young trees well cared for.

Grafting on the Peach.

Will pears do to graft on the peach, or will plums do well on the peach? How soon ought they to bear when grafted on the peach which is past three years old?

Pears cannot be grafted on peaches. Plums generally do well on the peach, and if the grafts are taken from bearing trees, should come into fruit the second season. The peach is more difficult to graft than other fruit trees, because of the drying back of the bark. Be extra careful in the waxing and be sure that the waxing remains good until the growth starts out well the following summer.

Young Trees Failing to Start.

Some peach and almond trees set out last spring lived, but made no growth. Should they be replaced with new stock? If not, what may be expected of them?

If your inactive trees have good plump dormant buds (though they may not be large buds), they may make good growth the coming summer, if the land is good and the moisture right for free growth.

Peach Planting in Alfalfa Sod.

Is it advisable to plant canning peaches in April, and will I gain time in growth and development? I want to set out eight acres in Tuscans or Phillips on deep rich soil near Yuba City. I have a pumping plant and can irrigate. The land has been in alfalfa for several years. I have in mind setting out trees without disturbing the alfalfa - until next plowing season. Do you think it advisable to use commercial fertilizer on ten-year-old Muirs?

Planting the best canning peaches on good peach soil near Yuba City seems to be about the safest line of fruit investment which can be undertaken. We doubt that you can get much growth from trees planted in an old stand of alfalfa without some effort to kill out the plant which now occupies the ground. Still, by deep digging, throwing out all the alfalfa roots and thorough hoeing during the growing season and keeping the alfalfa mowers from sawing off the tops of them, the trees may make a good start. As the alfalfa will have to be irrigated, April may not be too late to start the trees, providing you can find nursery stock which is still quite dormant. Probably ten-year-old peach trees will be very much improved by commercial fertilizers.

Prune on Almond.

What root is considered best for prune trees? The ranch lies above the creek. A friend is very partial to the almond root instead of the myrobalan, but I understand that the prune tree sometimes outgrows the almond root.

If you have a deep rather light soil which drains well and which there is, therefore, no danger of water standing during the rainy season, the almond root is perfectly satisfactory for the prune. It is a strong-growing root and keeps pace with the top growth well. The prune, in fact, is more apt to overgrow the myrobalan than the almond, and the myrobalan will not do well on light soils likely to dry out as the almond will.

Re-grafting Silver Prunes.

I have five acres of Silver prunes which produce very little fruit. The trees are strong and healthy. French prune trees adjoining bear regularly and heavily. Can I graft French prunes on the Silver trees? Will Silver prune trees take other grafts, such as apricots or apples?

The Silver prune is often unsatisfactory for reason of shy bearing. It is perfectly feasible to graft over the tree to the French prune and this has been done for years by different growers. Apricots will usually take on the plum stock, but are apt to over-grow it or else be dwarfed themselves, but the apricot is often worked upon a plum stock. Apples have no grafting affinity whatever for the plum.

French or Italian.

In the prune-growing district around Salem, Oregon, Italian prunes are grown exclusively for drying purposes. French prunes were considered worthless. Here in Sutter county, California, a great many French prunes are grown and we are advised to plant them, but would rather plant the Italian prune. Which would you advise us to set out in this part of the State?

The Italian or Fellenberg prune was grown to some extent in California 40 years and abandoned; it was not so sure in bearing as the French, and it was not the type of prune which we had ambition to excel with. The prune which we grow as the French is the true prune or plum of Agen. We should plant it and let the Oregon people have the Italian.

Myrobalan Seedlings.

I am sending two small plums which I am told are Myrobalan plum. I desire to grow seedlings on which later to bud and graft French prunes. If these are Myrobalan plums, will trees from them be as good as trees from pits that were imported?

The fruits are Myrobalan plums, and their seedlings would be suitable for the French prune, providing the trees which bear them are strong, thrifty growing trees. There is great variation in the colors of the Myrobalan seedlings, from light yellow to dark red, and it is the satisfactory growth of the tree rather than the character of the fruit which one has to bear in mind when growing seedlings from selected trees instead of depending so largely on imported seedlings.

Drying Plums and Prunes.

I have plum trees of various kinds that are loaded with fruit. I do not know if any are of the variety used for drying as prunes: I know nothing of the process of making or drying prunes. One man suggests that I dip them for four or live minutes in a 3 or 4 per cent solution of lye and then place them in the sun.

Dipping your plums is right providing they are very sweet, as they will dry like prunes without removing the pit. If they are plums that are commercially used for shipping, without enough sugar to dry as prunes, the pit must be removed. Drying in this way, you do not need to use lye, which is simply for the purpose of cracking the skin so that the moisture can be more readily evaporated. There is no danger in using the necessary amount of lye. Less is used than in making hominy.

The Sugar Prune.

What is the commercial value of the Sugar prune? Is there any other early ripening variety better than the Sugar?

It is selling very well as a cured prune, and growers in the northern bay counties especially have done so well that they are extending their plantings. It is coarser in flesh than the French and generally flatter in flavor when cooked and thus falls below the ideal of a cured prune, but it has compensating characters, such as early ripening, with which no other prune compares. The Sugar is also valuable as a shipping plum to Eastern markets.

Glossing Dried Prunes.

Will you give the method for giving the gloss to dried French prunes?

There are various methods. One pound of glycerine to 20 gallons of water; a quick dip in the mixture very hot gives a good finish. Where a clear bloom rather than a shine, is desired, five pounds of common salt to 100 gallons of water, also dipped hot, gives a good effect. Some use a thin syrup made by boiling small prunes in water (by stove or steam) and thinning with water to produce the result desired. Steam cooking avoids bad flavor by burning. The salt dip is probably the most widely used.

Price of Prunes on a Size Basis.

Explain the grading in price of prunes. For instance, if the base price is, say, five and three-fourths cents, what size does this refer to, and how is the price for other sizes calculated? Also, what is the meaning of the phrase "four-size basis"?

Prunes, after being sold to the packer, are graded into different sizes, according to the number required to make a pound, and paid for on that basis. The four regular sizes are 60-70s, 70-80s, 80-90s, and 90-100s, which means that from 60 to 70 prunes are required to make a pound, and so on. The basis price is for prunes that weigh 80 to the pound. When the basis price is 5 3/4 cents, 80-90s are worth 1/4 cent less than this amount, or 5 1/2 cents. The next smaller size, 90-100s, are worth 1/2 cent less, or 5 cents, while prunes under this size are little but skin and pit and bring much less to the grower. For each next larger size there is a difference of 1/2 cent in favor of the grower, so that on the 5 3/4-cent basis 70-80s are worth 6 cents, and 60-70s 6 1/2 cents. This advance continues for the larger sizes, 30-40s, 40-50s, etc., but these quite often command a premium besides, which is fixed according to the supplies available and the demand for the various sizes. The sizes for which no premium or penalty is generally fixed are those from 60 to 100, four sizes, so that this basis of making contracts and sales is called the "four-size basis." The advantage that results in having this method of selling prunes can be seen by the fact that on a 5 3/4-cent basis the smallest of the four sizes will bring but 5 cents a pound, while 30-40s would bring, without any premium, 8 1/2 cents, and with 1 cent premium, 9 1/2 cents. This size has this season brought as high as 10 and 11 cents a pound. It may be noted here that no prunes are actually sold at just the basis price, as they are worth either less or more than this as they are smaller or larger than 80 to the pound. No matter what the basis price is, there is a difference of one-half cent between each size and the sizes nearest to it.

Pollinizing Plums.

How many rows of Robe de Sergeant prune trees should be alternated with the French prune (the common dried prune of commerce) to insure perfect fertilization of the blossoms?

The French prune is self-fertile; that is, it does not require the presence of other plum species for pollination of the blossoms. It is the Robe de Sergeant prune which is defective in pollination and which is presumably assisted by proximity to the French prune. If you wish to grow Robe de Sergeant prunes your question of interplanting would be pertinent, but if you desire only to grow French prunes you need not plant the Robe de Sergeant at all.

Cultivating Olives.

How deep should an olive orchard be plowed? I was told that by plowing deep I would injure my trees, in cutting up small rootlets and fibres which the olive extends through the surface soil. Is this so or not?

Plowing olives is like plowing other trees, the purpose being to get a workable soil deep enough to stand five or six inches of summer cultivation, usually. If you have old trees which have never been deeply plowed, you would destroy a lot of roots by deep plowing, and you should not start in and rip up all the land at once. You can gradually deepen the plowing, sacrificing fewer roots at a time, without injuring the trees if they are otherwise well circumstanced. Small rootlets and fibres in the surface soil do not count; they are quickly replaced, and if you do not destroy them, the whole surface soil, if moist enough, will be filled with a network of roots which will subsequently make decent working of the soil impossible.

Moving Old Olive Trees.

Would there be anything gained by transplanting old olive trees 6 to 8 inches in diameter over nursery stock? They would have to be shipped from Santa Clara to Butte county and grafted. Would they come into bearing any sooner and be as good trees? Could the large limbs be used to advantage? Would the fact that they are covered with smut cause any trouble?

Old olive trees can be successfully moved a long distance by cutting back, taking up a ball of earth, and possibly a short distance with bare roots if everything is favorable. But do not for a moment think them worth such an outlay for labor, freight and hauling which such a movement as you mention involves. The trees on arrival would probably only be firewood, and if they lived, the time required in getting a good growth and grafting, etc., would perhaps be as great as in bringing a young tree of the right kind to bearing, and the latter would be a better tree in every way. Large limbs can be split and used as cuttings, but the tree would be growth on one side and decay on the other. Use the smaller limbs for hard-wood cuttings and the balance for firewood. The smut shows that the trees are covered with scale insects and might indicate that it is better to burn up the whole outfit unless you learn to fight them.

Darkening Pickled Olives.

Is there anything that will make olives keep their black color when put into lye? When I put my first picking of ripe olives in lye, a large part of them turn green, the black leaving the fruit. My formula is one pound of lye to five gallons of water. Have you any better formula?

By exposing the olives to the light and air, either during the salting or immediately after, ripe olives may be given a uniformly black color. Also, fruit which is less ripe and which shows red and green patches after processing with lye, becomes an almost uniform dark brown color. To do this, the olives are removed from the brine and exposed to light and air freely for one or two days. Your lye was stronger than necessary. With ripe olives it is desirable to use salt and lye together to prevent softening, and the common prescription is two ounces of potash lye and four ounces of salt to the gallon of water after the bitterness is largely removed by using one or two treatments with two ounces of lye to the gallon without the salt. It is necessary to draw off the solution, rinse well, and put on fresh solution several times during the process to get the best results.

Seedling Olives Must Be Grafted.

Will olive trees grown from the olive seed be the right thing to plant? Will they be true to the parent tree or will they have to be grafted?

Olives which a seedling olive tree will bear will be, as a rule, very inferior and generally of the type of the wild olive. All such trees must be grafted in order to produce any particular variety which you desire.

Olives, Oranges and Peppers.

We have been told that olive trees easily become infested with a fungus disease which they then impart to the orange tree. The same objection is raised to the planting of pepper trees. May this be true in some parts of the State and not in others?

The fungus of which you have heard is the "black smut." It is a result, not a cause. It grows on the honey dew exuded from scale insects and if your trees have no scale they have no fungus. The olive trees and pepper trees may communicate this trouble to citrus trees, or vice versa - whichever gets it first gives it away to the other. If you will work hard enough to kill the scale wherever it appears you can have all these trees, but, of course, it costs a lot to fight scale on big pepper trees, and it is, therefore, wisest usually to choose an ornamental tree not likely to accept the scale.

Budding Olive Seedlings.

I have planted olive seeds which are just sprouting now. Can these be budded next June or July in the nursery row, or can they be bench-grafted the following winter?

Your seedlings may make growth enough to spur-bud this summer. The ordinary plate-bud does not take freely with the olive. Some of them may do this; other seedlings may be slow and have to be budded in the second summer. Watch the size and the sap flow so that the bark will lift well - which may not be at just the time that deciduous trees are budded. It may be both earlier or later in the season. Graft evergreens like the olive in the nursery row; not by bench grafting.

Budding Old Olives.

I have seedling olive trees, set out in 1904, which I wish to change over to the Ascolano variety. Which is the best way to do it, by budding or grafting, and what is the proper time?

Twig-budding brings the sap of the stock to bear upon a young lateral or tip bud, which is much easier to start than dormant buds used either as buds or grafts. A short twig about an inch and a half in length is taken with some of the bark of the small branch from which it starts, and both twig and bark at its base are put in a bark slit like an ordinary shield bud and tied closely with a waxed band, although if the sap is moving freely it would probably do with a string or raffia tie. Put in such buds as growth is starting in the spring.

Olives from Small Cuttings.

In the rooting of small soft-wood olive cuttings is it necessary to cover same with glass - say perhaps prepare a cold-frame and put stable manure in the bottom with about eight inches of sand on top?

It ceases to be a cold-frame when you cover in manure for bottom heat; it becomes a hotbed. Varieties of olives differ greatly in the readiness with which they start from small cuttings. Some start freely and grow well in boxes of sand under partial shade - like a lath house or cover. Some need bottom heat in such a hotbed as you describe with a cloth over; some start well in a cold-frame with a lath cover. To get the best results with all kinds, it is safer to use some more heat than comes from exposure to ordinary temperatures - either by concentration, as in a covered frame, or by a mild bottom heat. If you have glass frames or greenhouse, they are, of course, desirable, but much can be done without that expense.

Olives from Large Cuttings.

I am about to take olive cuttings from one-half to one inch thick and 54 to 20 inches long, and wish to root them in nursery rows. Please advise me if it is necessary to plant under half shade? Also, can same be planted out right away, or should they be buried in trenches for a while before setting out? Would it be best to strip all leaves or branches off, or leave one on? How many buds should be left above ground?

Plant in open ground in the coast district generally; in the interior a lath (or litter shade not too dense) is desirable in places where high dry heat is expected and where sprinkling under the cover may be desirable. Plant out when the soil is right as to warmth and moisture, which is usually a little later than this in the central and northern parts of the State. Remove all leaves and twigs and plant about three-quarters of the length in the soil, which should be a well-drained sandy loam. The cuttings can be taken directly from the trees and need not be bedded. If the cuttings come some distance and get end-dried, make a fresh cut at planting. If shriveled at all, soak a few hours in water before planting out.

Trimming Up Olives.

Limbs are shooting out too low on my olive trees. Would it be right to trim them up while dormant this winter, or should I let them grow another year before doing so? I think I want the first limbs to start at 18 to 20 inches above the ground.

Take off the lower shoots whenever your knife is sharp. Do not let them grow another year. Theoretically, the best time to remove them is toward the end of the dormant season, but if they are not large as compared with the whole growth of the tree, go to it any time.

Canning Olives.

What is the recipe for preserving olives by heat, and how long do they have to remain in the heated state?

Canning olives is a process, not a recipe, and it has to be operated with judgment. It resembles, of course, the common process of canning other fruits and vegetables. It has been demonstrated that heating up to 175° Fahrenheit is effective to keep olives in sealed containers for over two years. The heating was done in the jars in the usual canning way for several minutes after 175° was reached, to be sure the contents were heated through.

Renewing Olive Trees.

I have olive trees on first-class land; no pest of any kind is apparent. The trees look healthy in every way, and average about 12 inches at the butt and 30 feet high. They have borne fruit, but for the last three years have not borne. I am advised to cut back to stumps, 5 or 6 feet high, and start new tops.

Unsatisfactory olive trees may be cut back, but not to such an extent as you mention. Thin out the branches if too thick and cut back or remove those which interfere, but to cut back to a stump would force out a very thick mass of brush which you would have to afterward go into and thin out desperately. The branches which you decide to retain may be cut back to twelve or fifteen feet from the ground. This would have the effect of giving you plenty of new thrifty wood, which is desirable for the fruiting of the olive, but we cannot guarantee that this treatment will make the trees satisfactory bearers. Are you sure they are receiving water enough? If not, give them more next summer. Also give the land a good coat of stable manure and plow under when the land is right for the plow.

Growing Olives from Seed.

How are seedlings grown from olive seeds?

Growing olives from seeds is promoted by assisting nature to break the hard shell. This can be done by pinching carefully with ordinary wire pliers until the shell cracks without injury to the kernel, or the shell may be cut into with a file, making a very small aperture to admit moisture. The French have specially contrived pliers with a stop which admits cracking and prevents crushing. Olive seeds in their natural condition germinate slowly and irregularly. They must be kept moist and planted about an inch deep in sandy loam, covering with chaff or litter to prevent drying of the surface. Before experimenting with olive pits, crack a few to see if they have good plump kernels. Seedling olives must be grafted, of course, to be sure of getting the variety you want. For this reason growth from cuttings is almost universal.

Neglected Olive Trees.

I have a lot of olive trees which have grown up around the old stumps. They are large trees and some of them have six or eight trunks. Should I cut away all but one trunk or let them alone? There are some of the trees with small olives; others none.

If the olive trees which were originally planted were trained at first and still have a good trunk and tree form, the suckers which have intruded from below should be removed. If, however, the trees have been allowed to grow many branches from below, so that there is really no single tree remaining, make a selection of four or five of the best shoots and grow the trees in large bush form, shortening in the higher growth so as to bring the fruit within easier reach and reduce the cost of picking. You can also develop a single shoot into a tree as you suggest. Of course, you must determine whether the trees as they now stand are of a variety which is worth growing. If they are all bearing very small fruit, it would be a question whether they were worth keeping at all, because grafting on the kind of growth which you describe would be unlikely to yield satisfactory tree forms, though you might get a good deal of fruit from them.

Olives from Cuttings.

I have two choice olive trees on my place. I am anxious to get trees from these old ones and do not know how to go about it. Can I grow the young trees by using cuttings or slips from these old trees ? If so, when is the proper time to select the cuttings, and how should they be planted?

Take cuttings of old wood, one-half or three-quarters of an inch in diameter, about ten inches long, and plant them about three-quarters of their length in a sandy loam soil in a row so water can be run alongside as may be necessary to keep the soil moist but not too wet. Such dormant cuttings can be put in when the soil begins to warm up with the spring sunshine. They can be put in the places where you desire them to grow in one or two years. Olives, like other evergreen trees, should be transplanted in the spring when there is heat enough to induce them to take hold at once in their new places, and not during the winter when dormant deciduous trees are best transplanted.

Water and Frost.

I have in mind two pieces of land well adapted to citrus culture. Both have the same elevation, soil, climate and water conditions, except that one piece is a mile of the Kaweah river, while the other is four or five miles distant. In case of a frost, all conditions being about the same, which piece would you consider to be liable to suffer the more? In the heavy frost of last December, while neither sustained any great damage, that portion of the ground nearer the river seemed to sustain the less. Is this correct in theory? The Kaweah river at this point is a good-sized stream of rapidly flowing water.

The land near the river, conditions of elevation being similar, would be less liable to frost. There are a good many instances where the presence of a considerable body of water prevents the lowering of the temperature of the air immediately adjacent. It is so at various points along the Sacramento river, and it is recognized as a general principle that bodies of water exert a warming influence upon their immediate environment even in regions with a hard winter. How much it may count for must be determined by taking other conditions into the account also.

Thinning Oranges.

Is it advisable to thin fruit on young citrus trees? Our trees have been bearing about three years, but they are still small trees. The oranges and grape fruit ripen well and are large and of excellent quality, but the trees seem overloaded.

The size of oranges on over-burdened trees can be increased by thinning, just as other fruits are enlarged, but it is not systematically undertaken as with peaches and apricots, because it is not so necessary and because it is easy to get oranges on young trees too large and to be discounted for over-sized coarse fruit. Removing part of the fruit from young trees is often done - for the good of the tree, not for the good of the fruit. It should be done after the natural drop takes place, during the summer.

Wind-blown Orange Trees.

What would you do for citrus trees five years old that have been badly blown out of shape?

Such trees must be trued up by pruning into the wind; that is, cutting to outside buds on the windward side and to inside buds on the lee side; also reducing the weight by pruning away branches which have been blown too far to the leeward. Sometimes trees can be straightened by moving part of the soil and pulling into the wind and bracing there by a good prop on the leeward side, but that, of course, is not practicable if the trees have attained too much size.

Handling Balled Citrus Trees.

I have some orange and lemon trees which were sent me with their roots balled up with dirt and sacks. As we are still having frosts I have not wanted to set them out. Would it not be better to let them stay as they are and keep the sacks wet (they have a sack box over them) than to put them out while the frosts last?

Your citrus trees will not be injured for a time unless mold should set in from the wet sacks. Get them into the ground as soon as the soil comes into good condition, and cover the top for a time after they are planted to protect them against frosts. This would be better than to hold them too long in the balls, but do not plant in cold, wet soil; hold them longer as they are.

The Navel Not Thornless.

I have lately purchased some Washington navel orange trees, and upon arrival I find they have thorns upon them. I thought the Washington navels were thornless.

The navel orange tree is not thornless. It is described as a medium thorny variety, so that the finding of thorns upon the trees would not be in itself sufficient indication that they were not of the right variety.

Over-size Oranges.

I have some orange trees in a disintegrated granite with a good many small pieces of rock still remaining in the soil. What I wish to know is whether it is probably something in the soil that makes them grow too large, or is it probably the method of treatment? What treatment should be adopted to guard against this excessive growth?

Young trees have a natural disposition to produce outside sizes of fruit, and this is sometimes aggravated by excessive use of fertilizers, sometimes by over-irrigation. We would cease to fertilize for a time and to regulate irrigation so that the trees will have enough to be thrifty without undertaking excessive growth. Such soil as you describe is sometimes very rich at the beginning in available plant food, and fertilization should be delayed until this excess has been appropriated by the tree.

Budding or Grafting in Orange Orchard.

I have land now ready to be planted to oranges, but it is impossible for me to buy the necessary budded stock now or even later this year. Would you advise me to plant the "sour stock" as it comes from the nursery and have it budded or crown-budded later? Are there any real objections to this method, and, if so, what are they?

It is perfectly feasible to plant sour-stock seedlings and to graft them afterward to whatever variety of oranges you desire to grow, but it is undoubtedly better to pay a pretty good price for budded trees of the kind you desire rather than incur the delay and the irregular growth of young trees budded or grafted in the field. There is also danger of an irregular stand from accidental injuries to new growth started in the field without the protection which it finds in the nursery row.

Budding Oranges.

How late in the fall can budding of orange trees be done - plants that are two years old - and what advantage, if any, is late budding? What shall I do with some old trees that were budded about two months ago and are still green but not sprouted yet? The budding was done on young shoots.

Late budding of the orange can be done as late as the bark will slip well; usually, however, not quite so late as this. Such buds are preferred because in the experience of most people they make stronger growth than those put in in the spring. Such buds are not expected to grow until the lowest temperatures of the winter are over. The buds which you speak of as green but still dormant are doing just what they ought to do. They will start when they get ready.

Under-pruning of Orange Trees.

My Washington Navels have a very heavy crop on the lower limbs, as is usual. These branches are so low down that many of the oranges lie on the ground, and it takes a good deal of time to prop them up so that they will not touch the ground. What would be the result of pruning off these low branches, after the fruit is off? Will the same amount of fruit be produced by the fruit growing on the limbs higher up?

Certainly, raise the branches of the orange trees by removing the lowest branches or parts of branches which reach to the ground. A little later others will sag down and this under-pruning will have to be continuous. It would be better to do this than to undertake any radical removal of the lower branches. The progressive removal as becomes necessary will not appreciably reduce the fruiting and will be in many ways desirable.

Keeping Citrus Trees Low.

My tangerines last fall shot up like lemon trees - a dozen to twenty shoots two or three feet high. The trees are eight years old and are loaded with bloom and some of the shoots have buds and bloom clear to the top. Some shoots have no bloom. What should I do with these shoots? Cut them back like lemons or let them remain?

You must shorten the shoots if you desire to have a low tree. This will cause their branching and it will be necessary, therefore, to remove some of the shoots entirely, either now or later, in order that the tree will not become too compact.

Dying Back of Fruit Trees.

I have a few orange and lemon trees that are starting to die. One tree has died on the top. What kind of spray shall I use?

The dying back of a tree at the top indicates that the trouble is in the roots, and it is usually due to standing water in the soil, resulting either from excessive application of water or because the soil is too retentive to distribute an amount of water which might not be excessive on a lighter soil which would allow of its freer movement. Dig down near the tree and see if you have not a muddy subsoil. The same trouble would result if the subsoil is too dry, and that also you can ascertain by digging. If you find moisture ample, and yet not excessive, the injury to the root might be due to the presence of alkali, or to excessive use of fertilizers. The cause of the trouble has to be determined by local examination and cannot be prescribed on the basis of a description of the plant. It cannot be cured by spraying unless specific parasite is found which can be killed by it.

Young Trees Dropping Fruit.

I have a few citrus fruit trees about three years old. They have made a good growth and are between seven and eight feet high with a good shaped top or head. I did not expect any fruit last year and did not have any. This spring they blossomed irregularly at blooming time, but quite an amount of fruit set and grew as large as marbles, some of it the size of a walnut, but lately it has about all fallen off the trees.

There is always more or less dropping from fruit trees. Some years large numbers of oranges drop. There may be many causes, and the trouble has thus far not been found preventable. When the foliage is good and the growth satisfactory, the young tree is certainly not in need of anything. It is rather more likely that fruit is dropped by the young trees owing to their excessive vegetative vigor, for it is a general fact that fruit trees which are growing very fast are less certain in fruit-setting. It is, of course, possible that you have been forcing such action by too free use of water. You will do well to let your trees go along so long as they appear thrifty and satisfactory, and expect better fruiting when they become older.

Orange Training.

Is not a single leader in an orange tree more desirable than the much-forked tree so commonly seen! Can a single-leader tree be made from the nursery trees which have already formed their heads, by cutting off the heads below so that only a straight stick without any branches is left?

An orange tree with a central leader would not be at all satisfactory if it were carried very high. Of course, a central stem can be to advantage taken higher than it is often done, but we would not think of growing an orange tree with a central stem to the apex. The laterals would droop, crowd down upon each other badly, open the center to sunburn, and encourage also a growth of central suckers and occasion an amount of pruning altogether beyond what is necessary with a properly branched tree without a central stem.

Curing Citron.

I wish to know a way to cure citrons at home. I have a fine tree that has borne very fine-looking fruit for the past two years.

An outline for the preparation of candied citron is as follows: The fruit, before assuming a yellow color, and also when bright yellow, is picked and placed in barrels filled with brine, and left for at least a month. The brine is renewed several times, and the fruit allowed to remain in it until required for use, often for a period of four or five months. When the citrons are to be candied they are taken from the barrels and boiled in fresh water to soften them. They are then cut into halves, the seed and pulp are removed, and the fruit is again immersed in cold water, soon becoming of a greenish color. After this it is placed in large earthen jars, covered with hot syrup, and allowed to stand about three weeks. During this time the strength of the syrup is gradually increased. The fruit is then put into boilers with crystallized sugar dissolved in a small quantity of water, and cooked; then allowed to cool, and boiled again until it will take up no more sugar. It is then dried and packed in wooden boxes.

Crops Between Orange Trees.

What crop can I plant between rows of young orange trees to utilize the ground as well as pay a little something?

It depends not alone upon what will grow, but upon what can be profitably sold or used on the place, and unless sure of that, it is usually better not to undertake planting between young trees but rather to cultivate well, irrigate intelligently, and trust for the reward in a better growth and later productiveness of the trees. It is clear, California experience that planting between trees except to things which are demonstrated to be profitable should not be undertaken, and where one does not need immediate returns is, as a rule, undesirable. The growth of a strip of alfalfa, if one is careful not to submerge the trees by over-irrigation, would be the best thing one could undertake for the purpose of improving the soil by increasing the humus content, reducing the amount of reflected heat from a clean surface, and is otherwise desirable wherever moisture is available for it. You could also grow cow peas for the good of the land if not for other profit. You can, of course, grow small fruits and vegetables for home use if you will cultivate well. Common field crops, with scant cultivation, will generally cause you to lose more from the bad condition in which they leave the soil than you can gain from the use or sale of the crop.

Navels and Valencias.

Navel trees are being budded to Valencias in southern California, because of the higher price received for the late-ripening Valencias. Are the orchards in central and northern California being planted in Navels, and is there any difference in soil or climate requirements of Navels and Valencias?

There is no particular difference in the soil requirements of Valencia and Navel oranges. They are both budded on the same root. The desirability of Navel oranges in the upper citrus districts arises from the fact that the policy of those districts at the present time is to produce an early orange. This they could not accomplish by growing the Valencia. The great advantage of the Valencia in southern California, on the other hand, lies in the very fact that it is late and that it can be marketed in midsummer and early autumn when there are no Navels available from anywhere.

Orange Seedlings.

What about planting the seed from St. Michael's oranges or of grapefruit for a seed-bed to be budded to Valencias?

Good plump St. Michael's seeds would be all right if you desire to use sweet seedling stock. Grapefruit seedlings are good and quite widely used, though the general preference is for sour-stock seedlings.
