In a previous chapter, reference has been made to the necessity of thorough cultivation of the soil among young trees; but the importance of the proper attention to orchard culture is so great, that it deserves separate consideration. The thorough preparation of the soil before committing the roots of our trees to its embraces, which was fully impressed upon the orchardist, might have induced some to think that this was to be sufficient for them; but it ought rather to be inferred that any crop for which these preliminary labors were recommended, should receive continuous attentions of a similar character. It is with the desire that these views should obtain, and to indicate and specify, some of the most suitable modes of procedure, that the following remarks are presented in this place.
If the ground, which has been appropriated to the orchard, be also occupied as farming land, as is usually done for a few years after planting, while the trees are small, it should be exclusively devoted to hoed crops; by which is meant those that require constant cultivation and stirring of the soil. Indian corn is a favorite on account of the thorough culture which is bestowed upon it, but there are some objectors to its use; by such it is considered too rank a grower; it is thought to absorb too much of the moisture of the soil, and too greatly to over-shadow the young trees if they be so small as has been recommended under the head of Selection and Planting. To this objection, however, it is urged by others that the partial shade during the latter part of summer is a benefit rather than an injury. If the stalks be left standing upon the ground during the winter, they modify the force of the winds, and may even be of benefit, by the protection they furnish to the stems of the young trees; and when they fall to the ground, with their abundant foliage, these materials constitute a winter mulching of considerable value. Even if the fodder has been cut up, as is usually done by prudent farmers, the shocks scattered through the fields must exercise a considerable protecting influence.
Melons, cucumbers, cabbages, potatoes, turnips, and other root crops, which require frequent cultivation, are preferred by some orchardists, because of their being lower, and thus they will shade only the surface of the ground, without affecting the trees themselves. Let it ever be remembered, particularly in respect to soils that are of poor or of moderate fertility, that all these crops will remove their full share of plant-food from the land that we have already appropriated to another object, and that the main crop which we desire to draw its sustenance from the earth for a long series of years may thus be robbed of its proper nourishment. Under such circumstances we must meet the emergency by applications of fertilizing materials. I am aware that it may be urged by the theorists of agriculture, that these crops call upon the soil for different elements, and that, according to the customary views of the objects attained by a rotation, they may even be of advantage to those which are to follow. Others will make the practical observation that the fertilizing materials of common use in modern agriculture, may so readily be applied to compensate for these abstractions from the soil, that this is a matter of little moment, and not worthy of serious consideration. But it should be observed that, while men will often be induced to apply fertilizers to the temporary crop, counting upon an immediate return for their outlay, they seldom feel willing to make any return to the soil in compensation for what they have already removed from it, and rather wait until the necessity for such enrichment becomes painfully apparent in the diminished productiveness of their fields.
Hoed crops, such as those above mentioned, should alone be allowed to occupy the space between the young trees, and on no account should any white straw crops, or grasses be introduced, at least for several years, nor until the orchard shall have become well established. In many species of fruits, it is undoubtedly better to keep up the surface cultivation continuously, at least wherever the characters of the site and soil will permit it; but there are many situations where the abruptness of the declivities appropriated to fruit-growing, and often admirably adapted to such purpose, absolutely forbid continued cultivation. In such places it will be necessary soon to withdraw the plow, and to depend upon loosening the soil about the trees with the spade or fork, and upon the mellowing and meliorating effects of mulching. The expense of all the operations that are performed by human labor renders them inapplicable, except in small orchards and gardens; and in all large plantations we must depend upon the common earth-workers that are drawn by horses. Among these, a preference should be given to such as stir and pulverize the soil near the surface only; shallow culture of the upper layers of earth effects the objects in view better than that which is deeper. The intruding weeds are subdued and a mellow condition of the earth is the result, while the roots are not torn and bruised, but are encouraged to turn their feeding fibres into the stratum of mellow soil above them. When the trees have become well established, or when the nature of the soil and the broken character of the surface of the orchard require it, we may seed down the ground with clover, which is preferred to any of the grasses: the broad foliage will shade the ground, and may remain on the surface as a mulch, or be moderately pastured by suitable stock.
