Layout of the area for the orchard
The degree of threat to the existence of fruit trees and shrubs by frosts in winter, and their buds or flowers by spring frosts depend very much on the site, in which the orchard grows. Air, As you know, the colder it is, the heavier it is. The coldest air is just above the ground. In uneven terrain, the valley bottoms and all closed depressions are in fact reservoirs, where the coldest air flows from the area. It's easy to see that in winter, during frosts, and also in spring during frosts, the air temperature on the slopes of the hills is 3-5 ° C higher than in the adjacent valleys. Such a difference, in the temperature range below -25 ° C, in severe winters, it often determines survival without major damage or even death of trees. Likewise, in spring, flowers of trees and shrubs can most often survive a temperature drop of -1 ° C to -3 ° C, but, as a rule, they die, when the temperature drops to -5 ° C and still less to -7 ° .
Temperature differences, during critical periods for trees and shrubs, depending on the terrain, they make, that the best positions for orchards and berries are slight slopes.
