Poor tree growth and the appearance of stump strouts
At the base of the tree, the bark on the main stem is sloughing off (photo at right). To me, this indicates that the conductive tissues (xylem and phloem) in the stem have been damaged, interrupting the normal flow of water and nutrients. Its no wonder the top growth on this tree is so anemic.
The growth of stump sprouts is the tree's way of replacing the damaged portion of the tree with healthy stems that support large, healthy leaves.
This tree is a seedling growing in our pecan breeding plots and will remain a seedling in the future. If you need to coppice a grafted tree, plan to re-graft the tree in a year or two.
