In our section we have very good Persian walnut varieties of Carpathian and other European sources. I have planted some of all strains and varieties. My place faces northwest on a good elevation. My experience with trees there is that we have no winter injury. We can grow trees there that cannot be grown on some place which is situated low, and therefore does not have enough air circulation. Damage is done after heavy frosts when the sun comes out suddenly. That is what damages the trees—not the cold.
If you take trees and put them in a temperature of 35 to 40 degrees below zero and bring them out to thaw gradually no harm is done. Most people buy trees and plant them in low places; that is the error. We have planted trees where the wind is very heavy throughout the winter and in the spring I found that these trees stood up wonderfully well; whereas, we have European walnut trees with a trunk diameter of about 12 to 14 inches that in one year froze two to six feet—about three to four years growth. If you plant your trees on a fairly good elevation you can be assured of a good nut crop. In planting nut trees I do not know what kind of fertilizer you use, but I always use well decayed cow manure and put a little right around the root system. I never use fresh manure and never use poultry, sheep, or horse manure. They are bad for trees as they are very high in ammonia and this does damage to the trees.
