FIG. 1. A CALIFORNIA ALMOND ORCHARD.
That almond culture in California is rapidly becoming an important and successful industry, we have an ocular demonstration in the tons of these valuable nuts received from there in the past few years, and placed on sale in Eastern markets. If one man, by his individual efforts, can revolutionize or establish a great industry in a region as large as the State of California, it is not too much to expect that something of the kind could be done elsewhere, with the combined efforts of several men. If the varieties heretofore tried in the East are unsuited to the climate, it is certainly within the range of probabilities that others better adapted to surrounding conditions can be produced. The native grape, raspberry and strawberry have had a history similar to the almond, but now all are extensively and successfully cultivated.
Propagation of the Almond.-The propagation of the almond is identical with that of the peach: that is, from seed to procure new varieties, or by budding the more desirable ones, when obtained, upon seedling almond, peach or plum stocks. The half-wild hard-shelled almond is probably the most congenial and best stock for this purpose, but seedlings of the peach are most generally employed because the most abundant and cheapest. Under certain conditions, such as cold, heavy, moist soils, and where rather dwarfish trees are desired, the plum may be employed with advantage as a stock, but it is not to be recommended for general orchard culture. In mild climates seedlings of the best of the soft-shelled varieties may be raised and planted in orchards without budding, but the nuts from such trees are likely to be somewhat variable in size and quality, although the trees will usually prove to be as healthy and productive as those subjected to artificial modes of propagation. If, however, the grower desires a uniform product, he must resort to the usual means of obtaining it; that is, multiplying superior or distinct varieties by budding, either upon peach, almond or other stocks. It is advisable, as well as exceedingly important, for all who intend or feel inclined to cultivate almonds in regions where the adaptation of this nut has not been fully established by years of practical experience, that seedlings should be raised in large numbers, and from these a selection be made to meet the requirements of the climate and other conditions under which they are to be propagated and grown. If spring frosts have been heretofore inimical to the cultivation of the almond, then the production of late-blooming varieties would be a remedy. There will also be variations in the season of ripening; some may come on too early, others far too late for special localities, but all these faults or variations may be readily overcome by raising seedlings, and then selecting for propagation those coming nearest fulfilling the requirements of local conditions or circumstances. It is by such experiments and means that fruit culture has reached its present position in this and all other countries, where it is practiced as an art or industrial pursuit. Varieties that have become exceedingly popular and profitable in one locality or country, may not have succeeded elsewhere, and this holds good with all cultivated plants.
In making experiments with the almond in regions where it has not been cultivated, but under conditions which appear to be favorable, I would certainly advise testing the well-known varieties first, and if these fail, then see what can be done in the way of producing new ones adapted to the locality and climate.
Raising Seedlings for Stocks.-In warm or moderately mild climates the nuts, whether peach or almond, may be planted soon after they are gathered in the fall, but should the weather continue warm and moist the nuts will sometimes sprout prematurely and the young sprouts get frosted later in the season, and for this reason it is better to store them in a cool room, packed in dry sand or soil, until the approach of steady cold weather, and then plant. Having lost choice kinds of nuts from being in too great haste in getting them into the ground in the fall, I am prompted to give this warning to those who have had no experience in raising nut trees. If not convenient to plant in the fall, nuts of all kinds may be packed in barrels, boxes, or similar vessels, mixed with or stratified with sharp sand or light soil, then stored in a dry, cool place,-a very cool cellar will answer, but in my experience, out of doors is preferable,-and in the shade of some evergreen tree or on the north side of a building, and there banked over with earth just sufficient to keep the nuts at an equably low temperature. It is advisable to have a few small holes in the bottom of the barrels or boxes, to insure proper drainage, should any considerable amount of water get in at the top; but this will not occur if the vessels are properly covered with boards when placed in position for winter.
It must also be kept in mind that mice, squirrels and chipmunks are fond of almonds and other kinds of edible nuts, and if placed where these little rodents can find them, they are sure to take a share, or perhaps the entire store, before their visits are discovered. I have known field mice to dig down under boxes of nuts, enlarge the holes left for drainage, and spend the winter among the chestnuts which I had put away for planting in spring. The safest way is to place fine wire netting on the bottom of the box, and then cover it with the same. Owing to the abundance of mice and other little nut-eating animals, I have never dared to plant out nuts in the fall, and so have always stored them in sand, but out of doors during the winter, and well covered with earth. In other localities it may be safe to sow in autumn, and if protection from vermin is required, coat the nuts with gas tar, the same as practiced by farmers in protecting seed corn against the attacks of crows and other corn-pulling birds. One pint of warm tar will be sufficient for a bushel of nuts, and the application is readily made by placing the nuts in a barrel, pouring the tar on them, and stirring with a stick until every nut is coated. To prevent the tar sticking to the hands in planting, dust the nuts with dry wood ashes, land plaster, or fine dry sand.
If peach stones are to be planted for stocks they may be put into the ground as soon as ready in autumn, because they are rarely disturbed by vermin; or if more convenient, mix with common soil, and in heaps, in the open ground, and leave in this position until spring, then pick out as they begin to sprout, and plant. The hard-shelled almond may be treated in the same way, only they are not to be handled quite as roughly as peach stones, and for protection it is best to put them in barrels or boxes, as described above.
When ready for planting take out the nuts and drop them in shallow drills, one every ten or twelve inches, then cover with about two inches of soil. It is to be supposed, of course, that a seed bed has been prepared, by thorough working over and enriching, if necessary, in advance of planting. The distance between the drills or rows should be sufficient to admit of cultivating the plants with a horse or mule, and cultivator, during the summer, and if this is done and the soil stirred often enough to keep down all weeds, the stocks should become large enough to admit of budding the first season; if not, then this operation must be deferred until the following year. But in case the seedlings are raised from choice varieties and to be left in their natural condition for fruiting, they may be lifted when one or two seasons old and set where they are to remain permanently.
The Season for Budding.-So much depends upon climate, location, and variation of seasons, that no special date or time can be given for budding trees of any kind, but it is always to be done while the stocks are in active growth, because the bark must part freely from the wood underneath, in order to admit of inserting the bud under it. If the buds are set too early in the season there is danger of a premature growth; that is, of pushing out a shoot in the fall instead of remaining dormant until the following spring. Under certain conditions, however, and for special purposes, it may be advisable to force the buds as soon as they have formed a union with the stock, but as a rule, in the propagation of hardy and half-hardy trees, it is better to keep the buds dormant during the cool or cold winter months.
Here in the Northern States we usually begin to look over our stocks during the latter part of July or first week in August, and note their progress and condition. Should they show the least signs of cessation of growth, we begin budding them, and push the work as rapidly as possible. If the season is a wet one the stocks may continue to grow and remain in good condition for budding until the middle of September; but in a dry season they may cease to grow in August, and it is these variable conditions which gives to the close observer and man of experience such an advantage over the novice in the propagation of plants. It is better to begin budding too early than to be a few days too late.
The operation called budding consists in taking a bud, with a small portion of the bark adjoining, from one plant, and inserting it in another, or in some other part of the same plant from which it was taken. The physiological principles which govern the operation are, that there must exist an affinity between the plant from which the bud is taken and the one upon which it is to be placed, and the nearer the relationship the more readily will it unite and the more perfect the union. For instance, the cultivated peach and almond are...
