Hi. Some trees that I transplant suffer a near death experience, turning brown and losing all foliage. I don't give up trying to bring them back, though, and I am often rewarded with a tree that comes back to life. The new growth, however, is at the very bottom. Attached are pics of a laurel schipp and a rose of sharon. I'm wondering if I must cut down to the live growth and let the trees start anew, or if with patience the rest will come back? It took 2 1/2 months to obtain this new growth. Any advice would be greatly appreciated. Thanks!
