| + | The best results in apple-growing are to be expected in general when the land is tilled. The reasons for tilling the orchard are those that apply to other crops,— to make plant-food available, to extend the area in which the roots can grow, to conserve moisture. It is especially important, in our hot and sunny country, that the roots extend deep enough to escape the disastrous effects of drought. 1 he ideal treatment of orchard land is to fit the ground deep before the trees are planted, to plow deep for a year or two or three in order to force the roots down and thoroughly to ameliorate the soil, and to practise shallow tillage to conserve moisture. Since trees make most of their growth early in the season, the tillage should be begun as soon as the land is fit in spring; and it may be discontinued by midsummer or August. This cessation of the tillage allows of the growing of some cover-crop or catch-crop late in the season, in order to provide humus and to improve the physical texture of the soil. If the land is well handled in the first few years, it will not be necessary to turn a furrow in the orchard frequently thereafter, but merely to loosen the surface in the spring with a spading-harrow, spring-tooth harrow, or other tool, to reestablish the surface mulch. The only reasons for turning a furrow will occur when the land is so hard that the surface tools cannot mellow the surface, or when it is desirable to turn under a green-manure crop. Even hard lands may be got in such condition, by means of tillage and green-manures, that they may be worked up with harrow tools when the orchard comes into bearing. Plowing the orchard, therefore, has two legitimate objects: to mellow and ameliorate the land to a considerable depth, so that the roots may forage deep; to turn under a cover-crop. The former purpose should not be necessary after the first few plowings. An incidental object of plowing is to facilitate the making of the annual surface mulch; and this mulch is to save the moisture. | ||
| − | + | On good lands in which there is a sufficient natural supply of moisture, the sod-mulch treatment may take the place of tillage. This procedure keeps the land in sod, and the grass is mown and allowed to remain on the ground or is spread under the trees. | |

Forty feet apart each way is the standard distance for apple trees; but some varieties, as the Wagener and the crabs, may be set closer. In the South and on the plains, trees may be set closer, as they do not attain such great size as in the northeastern states. In general, it is best to devote the land to apples alone; but persons who are willing to give the plantation the best of care may plant other trees between the apples as fillers.

Two to three hundred pounds to the acre of the nitrate of soda or sulfate of ammonia are liberal applications on well-tilled lands. If the trees are making vigorous growth, the probability is that they are not in need of more nitrogen. Potash and phosphoric acid may then be applied. Three hundred pounds of muriate of potash, or other concentrated material, should be sufficient for an acre, under ordinary conditions. As a rule, all orchards in full bearing should have a liberal annual application of fertilizing materials.

Spraying for the worm should be performed as soon as the last petals fall; for the scab as soon as the buds are well burst. In badly infected regions and on very susceptible varieties, it may be necessary to spray first for the scab before the buds swell.
