I bought 4 pecan trees from the nursery. I didn't mail order them but went to the nursery to get them. Nice nursery but no customer service. When the nursery guy helped me pick the trees, I asked if those were healthy because the bark looked damaged. They were grafted in 3-4 places up the trunk and some of the bark looked like it was peeling off. He said that it was normal and once the tree matures, you won't ever notice it so I took his word for it. I planted them all in the same area with the same soil type, kept them watered at the same rate, same planting method....3 of them were rotten way before the growing season was over. A tree cannot rot that fast and I did not over water or under water them hence one still living and doing fine. They don't have a guarantee on their trees and that is ok if you receive a healthy tree that at least leaves out but not ok if I ask about the health of the tree and he assures me they are fine when they are not. I emailed my complaint to them and did not receive a reply.
