SOME HINTS ON RENOVATING OLD ORCHARDS
Nearly every general farm in the humid part of the United States has its small, old apple orchard. For the most part these orchards were planted in order to have a home source of supply of this popular fruit. In fact, but few orchards have been planted on a commercial scale with a view of selling the fruit, until recently and outside of a few sections. Therefore, as a rule we find these old farm orchards to consist of a few acres containing from twenty-five to two hundred trees. These trees are usually good standard varieties which have been the source of much apple "sass," many an apple pie, and many a barrel of cider-vinegar.
Not having been set for profit, these trees received little care. Orchards were cropped in the regular rotation, or with hay, or pastured. Farmers then knew little of modern methods of orchard management. The orchard was regarded as an incumbrance to the land, which had to be farmed to as good advantage as possible under the circumstances, and if the apple trees by any chance yielded a crop, the owner regarded himself as fortunate indeed.
But conditions have now changed. Both local and foreign markets have been opened up and developed so that the demand for good fruit is great. It will be some time before the thousands of acres of orchards which have been and are being planted to meet this demand will be able to do so in any adequate way. It has been shown in Chapter I how heavy has been the falling off in the supply, even in the face of these heavy plantings. Meanwhile we must turn to the old neglected farm orchards for our supply of apples. Just at this particular time the renovation of these old orchards offers a splendid opportunity to increase the farm income.
The question is a live one on nearly every general farm in the East. Will it pay to try to renovate my old apple trees? If so, what should I do to make them profitable? What will it cost and what returns may be expected? The latter question will be taken up in the following chapter, but here we must try to indicate under what conditions it may pay to renovate an old orchard, as well as those under which it may not pay, and also how to go about the problem.
NECESSARY QUALITIES.--An apple orchard must have certain qualifications in order to make it worth while to spend the time and money necessary to accomplish the desired results. These we may take up briefly under five heads: (1) varieties, (2) age, (3) number or "stand" of trees, (4) vigor and health of the trees, and (5) soil, site, and location. The discussion of these subjects in Chapters II and III has equal application here, but we may perhaps point out their specific application more definitely in the case of the old neglected farm orchard.
(1) Varieties should be desirable sorts. If they are the best standard market varieties, as is often the case, so much the better. Otherwise little is gained by improving the tree and fruit. Poor or unknown varieties have little or no market value, except perhaps a very local one. If the trees are not too old and are fairly vigorous, poor varieties may sometimes be worked over by top grafting to better varieties. Characteristics which may make, a variety undesirable are: inferior quality; unattractiveness in color, shape, or size; lack of hardiness in the tree or keeping quality in the fruit; low yield; or being unknown in the market with its consequent small demand. Summer varieties are worth renovating only when they are in good demand in a nearby local market.
(2) Vigor is more important than age in the tree, but is closely correlated with it. Ordinarily one should hesitate to try to renovate a tree more than forty or fifty years old, but this must always depend almost wholly on its condition and other characteristics.
(3) In order to make a business of renovation and to do thorough work which means expense, there must be enough of the orchard to justify the expenditure of the time and money. This affects the results not only in expense, but in economy in management, equipment, and marketing. There should be at least an acre of say thirty trees, and better, more than that number to justify the expense of time and money necessary for renovation. One hundred trees would certainly justify it, other conditions being favorable. Then, too, the trees should be in such shape that they can be properly treated without too great trouble and expense, i.e., not too scattered or isolated or in the midst of regular fields better adapted for other crops.
(4) Vigor and good general health are of great importance. Many old trees are too far gone with neglect, having been too long starved or having their vitality too much weakened by disease to make an effort for their rehabilitation worth while. Good vigor, even though it be dormant, is absolutely essential. Disease weakens the tree, making the expense of renovation greater. Moreover, all diseased branches must be removed, requiring severe cutting and often seriously injuring the tree. Disease too often stunts the tree to such an extent as to make stimulation practically impossible. Such matters should be carefully looked into before attempting renovation.
(5) If the soil, site, and location are all unfavorable or even if two of these are not good, time and money are likely to be wasted on renovation. What constitutes unfavorable conditions in these respects has already been pointed out in Chapter III.
Practically the same principles of pruning, cultivation, fertilization and spraying apply in the management of the old orchard as in any other orchard. It may be well, however, to restate these, briefly pointing out their special value and application to the old neglected orchard together with the few modifications of practice necessary. The steps to be taken are four: (1) pruning, (2) fertilizing, (3) cultivating, and (4) spraying.
(1) PRUNING.--Old and long-neglected apple orchards usually have a large amount of dead wood in them. This may be removed at any time of the year, but fall and winter are good times to begin the work. If the trees are high and the limbs scattered and sprawling so that the middle of the trees is not well filled out, the trees should be headed back rather severely. Such trees may safely have their highest limbs cut back from five to ten feet. It is best not to remove too many branches in one year, but to spread severe cutting back over at least two years, as so much pruning at one time weakens the tree and causes an excessive growth of "suckers." Each limb should be cut back to a rather strong and vigorous lateral branch which may then take up the growth of the upright one. The effect of such heading back will be to stimulate the branches lower down and probably to bring in more or less "suckers." The following year the best of these suckers should be selected at proper points about the tree, headed in so as to develop their lateral buds, and encouraged by the removal of all other suckers to fill in the top and center of the tree in the way desired. All such severe heading in should best be done in the early spring.
(2) FERTILIZING.--At some time during the late fall or winter twelve to fifteen loads of stable manure should be applied broadcast on each acre, scattering it well out under the ends of the branches. This will amount to a load to from three to five trees. In case manure is not available, or sometimes even supplementary to it in cases where quick results are wanted 100 to 200 pounds of nitrate of soda, 300 to 500 pounds of acid phosphate, and 150 to 200 pounds of sulphate or muriate of potash should be applied in two applications as a top dressing in spring, as soon as growth starts, and thoroughly worked into the soil. This will give the trees an abundance of available plant food, which is usually badly needed, and help to stimulate them to a vigorous growth. Such heavy feeding may easily be overdone and should be adjusted according to conditions and the needs of the orchard.
(3) CULTIVATING.--If the orchard has been in sod for a number of years, as is often the case, it is usually best to plow it in the fall about four inches deep, just deep enough to turn under the sod. By so doing a large number of roots will probably be broken, but such injury will be much more than offset by the stimulus to the trees the next season. It is a good plan to apply the stable manure on the top of this plowed ground early in the winter. Fall plowing gives a better opportunity for rotting the sod and exposes to the winter action of the elements the soil, which is usually stale and inactive after lying so long unturned. In the spring the regular treatment with springtooth and spiketooth harrows should be followed as outlined in Chapter V.
(4) SPRAYING in the old orchard is essentially the same as elsewhere. It is necessary, however, to emphasize the first spray, the dormant one, winter strength on the wood. This is the most important spray for a neglected orchard and it should be very thoroughly applied. It is a sort of cleaning-up spray for scale, fungus, and insects which winter on the bark. In orchards where the San Jose scale is bad a strong lime-sulphur spray should also be used in the late fall in order to make doubly sure a thorough cleaning up. It is usually a pretty good plan to scrape old trees as high up as the rough, shaggy bark extends, destroying the scrapings. For this purpose an old and dull hoe does very well. This treatment will get rid of many insects by destroying them and their winter quarters.
PATCHING OLD TREES.--A few suggestions on patching up the weak places in an old tree may not be entirely out of place. The question is often asked, will it pay to fill up the decayed centers or sides of old trees? If the tree is otherwise desirable to save, it usually will. Scrape out all the dead and rotten material, cleaning down to the sound heart wood. Then fill up the cavity with a rough cement, being careful to exclude all air and finishing with a smooth, sloping surface so as to drain away all moisture. This treatment will probably prevent further decay and often acts as a substantial mechanical support.
Trees which are badly split or which have so grown that a heavy crop is likely to break them over should be braced with wires or bolts. Where the limbs are close together a bolt driven right through them with wide, strong washers at the ends is very effective in strengthening the tree. Where limbs must be braced from one side of the tree across to the other wires are the best to use. They may be fastened to bolts through the limbs with wide washers on the outside hooks on the inside, or by passing the wire around the branches. In the latter case some wide, fairly rigid material such as tin, pieces of wood, or heavy leather should be used to protect the tree from the wire which would otherwise cut into the bark and perhaps girdle the limb.
COST.--For the benefit of those who would like to get some idea of the probable cost of renovating old apple orchards, the following estimate made by the writer in a recent government publication on this subject is given. This estimate has been carefully made up from actual records kept on several New York farms. Because these costs are very variable according to the condition of the orchard, both maximum and minimum amounts are given per acre for the first year only.
Minimum Maximum cost cost
Plowing $2.00 $3.00 Manure, 10 to 20 loads at $1, or their equivalent in commercial fertilizer 10.00 20.00 Hauling manure 5.00 10.00 Pruning and hauling brush 5.00 10.00 Disking or harrowing twice 1.00 1.50 Disking or harrowing 3d or 4th time .50 1.00 Cultivating two to four times .50 1.00 Spraying once with L.S. dilution 1 to 9--material 2.00 4.00 Spraying once, L.S., labor 1.00 1.50 Spraying second time with L.S. dilution 1 to 40, labor and material 1.50 2.50 Spraying third time with same 1.50 2.50 ------ ------ Total cost $30.00 $57.00
