Northern Spy is very exacting in its soil requirements. A medium loam, underlaid by a heavy loam or a light clay loam, is excellent. Heavy soils give the Spy a greasy skin. Light soils cause the tree to grow upright and to bear fruit of poor flavor. The King likes a soil slightly lighter than the best Greening soils, but retentive of moisture. Hubbardson will utilize the sandiest soil of any northern variety, preferring rich, fine, sandy loams. The particular location of the apple orchard is largely a matter of convenience. It should be remembered, however, that the apple requires much and constant attention, therefore the orchard should be convenient of access. The product is rather bulky, so that the haul to the highway should be as short as possible. Other conditions being equally good there, the common location near the buildings and highway is best. THE SITE OF THE ORCHARD is a more important matter. Two essentials should be kept in mind, good air drainage and a considerable elevation. Although it is not so apparent and therefore less thought about, cold air runs down hill the same as water. Being heavier, it falls to the surface of the land, flowing out through the water channels and settling in pockets and depressions. Warm air, being lighter, rises. It is desirable to avoid conditions of stagnant air or cold air pockets where frost and fogs are liable to occur. A free movement of air, especially a draining away of cold air, is best secured by an elevation. Fifty to one hundred feet, or sometimes less, is usually sufficient, especially where there is good outlet below. Frosts occur in still, clear air and these conditions occur most frequently in the lower areas. Aspect or slope requires less attention. Southern exposures are warm and hasten bud development and opening in spring. Northern exposures are cold and retard the blossoming period. It is usually advisable to plant the apple on the colder slopes which hold it back in spring until all danger of late frosts is past. Northeast exposures are best as a general rule. Choose a slope away from the prevailing wind if possible. If this is impracticable it is often advisable to plant a wind break of pine, spruce, or a quick, thick growing native tree to protect the orchard from heavy winds. A large body of water is an important modifier of climate. Warming up more slowly in the spring, it retards vegetation by slowly giving up its cold. Vice versa, cooling more slowly in the fall giving up its heat wards off the early frosts. It is therefore desirable to locate near such bodies of water if possible. Their influence varies according to their size and depth, and the distance of the orchard from them. Good examples of this influence are the Chautauqua Grape Belt on the eastern shore of Lake Erie and the Western New York Apple Belt on the south shore of Lake Ontario.
