If a plant dies within the first year or two after being transplanted, the cause is almost always “transplant shock.” It would be extremely unusual for an insect or disease to cause an otherwise healthy transplant to die that quickly. So, the question becomes, “What is transplant shock and how do I prevent it from killing my plants?”
Roots, of course, are the lifeline of the plant. They transport water and nutrients up to the leaves as part of the photosynthesis process. Without these inputs, the plant cannot produce its own food and energy supply. Plants establish a natural balance between the size of the root system and the size of the above ground part of the plant. This assures the proper flow of water and nutrients up to the leaves. If stems are cut off, part of the root system dies back. If some of the root system is removed, parts stems and leaves will suffer damage or death.
