My father had such a beautiful sorrel tree in his yard that turned scarlet each fall. Now he is gone and the people that bought the house let the sorrel tree die of thirst. I have tried twice to grow a sorrel tree here in Middle Tennessee (zone 6) in my father's honor. The first time, the tree was doing well but then we had a 1,000 year flood. I kept trying to trench out the tree to save it, but it drowned. The second time I planted a smaller tree in a raised bed, but I think I must have put it in too much shade. I am going to try again. Does anyone have any suggestions to give the tree the best chance possible?
