Whether the orchard is planted in a crop or not, cultivation should begin about the time growth starts in spring. The ground should be plowed and leveled with a cultivator. After that, frequent shallow cultivation should be given with a light harrow or weeder. Once every week or ten days, if the weather is dry, will result in much good to the trees. If a shower should fall during one of these dry periods, the ground should be cultivated just as soon as it can be worked. A light harrow, which will break up the surface crust formed by the rain and leave instead a shallow mulch of pulverized soil, will go a long way toward conserving and holding the water which has been added by the recent rainfall. The cultivation of old orchards may vary somewhat from that given younger ones. Some recommend that the old orchard be seeded to grass (Bermuda or Johnson grass) and used as a pasture. This may answer in some cases, particularly on very rich, alluvial soils, but, in general, it will not do as a definite policy year in and year out. Those orchards planted in grass which the author has had an opportunity to examine, have usually shown a large percentage of trees with branches dead at the tips, "stagheaded," with yellow leaves and a general appearance of unthriftiness. It may have been that these orchards were planted in grass while the trees were too young. The better treatment, and the safer one to follow in old orchards, is to cultivate the ground in spring and sow down in cowpeas or some other legume. Beggarweed, velvet beans or soja beans will answer well in many localities. Allow these to make what growth they will, and, when dead and dry, plow them back into the soil. It may seem strange to cultivate a forest tree, but it is the plan to follow to get results. Good results could doubtless be secured by seeding the pecan orchard in alfalfa and using it for a hog pasture up to the ripening season. Cultivation should not be prolonged too late. If it be, the trees will continue to grow later than they should. Enough time will not be left in many sections before the coming of the first frosts. If the immature, sappy wood is caught by an early frost, severe injury may result. In the more southern extension of the pecan area cultivation can be carried on later than toward the northern limits of the region. Ordinarily, it is safest to cease cultivation not later than July the first to July the fifteenth. FERTILIZATION. On deep rich, alluvial soils the trees may not need to be fertilized, but many of the soils on which pecans have been set in orchard form, require to be fertilized to secure the best results. The three important plant foods required by plants and most frequently deficient in soils are nitrogen, phosphorus and potash. One or two or all three of these substances may have to be supplied.
