This "King of the Tree Fruits" will grow and, with proper care and cultivation, give good results on a variety of soils and in various climates. Most any kind of farm land that will produce a good crop of corn, wheat or potatoes is well suited and adapted to the growing of the Apple. Its favorite soils are a strong, rich loam of a limestone nature, or a deep strong, gravelly, many loam. Perhaps the best flavored and highest colored fruit is produced from a strong, rich sandy loam, with a gravelly sub-soil. It must be understood, however, that land with the gravelly sub-soil as above described is leechy, more or less depending on its general characteristics, consequently much more difficult to keep in a high state of fertility than ground with a clay sub-soil, it is a well-recognized fact that on the banks and interior sections of the Hudson River Valley, between New York City suburbs and Albany, there is produced in large variety a high standard of large, choice, fine appearing apples of the best flavor. The top soil along the Hudson River section varies from a light sandy loam to a dark loam, with a limestone mixture. This top soil has a body of itself from ten to twenty inches and is almost invariably underlaid with a clay sub-soil. This seems to be indisputable evidence that such land is especially adaptable to the successful production of the Apple; moreover it is a noticeable fact that the trees grow larger and live longer on this character of land than on any other.
Don't Plant Apple Trees on an excessive dry, warm soil; they may exist there for a while, but in the end it will be an all-round disappointment with money, and what is more important, valuable loss of time. Don't plant on excessively wet land, that is, land that is low and too moist to cultivate when the ordinary farm crops can be tilled to advantage. We want to warn all against planting the Apple on very low ground, even when the land is of an average dry nature; the trees never thrive well on these low lands. It is only occasionally that the blossoms escape the late Spring frosts and bear a crop of fruit. We have in this country such a varied list of soils and exposures suitable to the best cultivation of the apple that it seems like careless and suicidal indifference to select any of these uncongenial situations and destroy our chances of success in the beginning. The apple should not be planted on land underlaid with solid rock -- unless the rock is five feet below the ground surface.
