My weeping cherry tree has no sign of any flowers or leaves. However, there spouts of leafs coming out of the trunk. why?
I suspect that the cherry tree may be a grafted tree (a desireable tree attached to the trunk of a stronger tree) and that the graft may have failed. The sprouts along the trunk are from below the graft. That part of the tree is alive. The upper part of the tree is the grafted part which is what you want. It may simply be late in leafing out. Give it a little more time. If it does not leaf out, I would go back to the nursery where you bought it and have them evaluate the tree. Since the lower part of the tree is leafing out, the problem was not lack of care or water.
