Based on their growth to date, Ill have a double handfull to sell in about 25 years.
Ha ha! I'm doing the same with some apple trees. The only ones benefitting so far are the deer, who have killed 3 trees and nibbled all the lower branches off!
Try planting “Rosemary” around your trees. The deer hate it, won’t eat it, and supposedly won’t go through it. Additionally, you’ll have a supply of an fragrant herb for culinary use.
