RE: Purchasing trees
Those guys are right on the money about covering trees. My buddy planted 20 apple trees and did'nt cover them and the deer had a expensive snack on him. Another thing I did was to paint the bottom few feet with white paint. It's suppose to keep the trees from splitting in the winter due to the freezing and sun. I also wrap the bottom to keep mice and other critters from griddling them.
Good luck......marty
