Reduce other stresses to the plants that can further weaken them, such as dryness or pests. A tree that is weakened by lightning is very susceptible to pests. Lightning that completely destroys plant tissue around the circumference of the tree will prevent translocation of water by girdling it. Valuable old trees can be protected with lightning conductors installed by a professional arborist. Branches may break, and high winds can make the situation worse.
Evergreen plants are particularily susceptible.
Tissues inside the plant that carry water and nutrients throughout the plant may become damaged and remain unnoticed until dieback is evident in the spring. Do not be in a hurry to start pruning a branch which is bent out of shape, since in a few days it will may straighten on its own. Do not remove ice from a plant, since additional damage due to breakage may occur. Cankers may form in these areas. Wrap the trunks of newly planted trees with tree-wrapping paper for the first two winters, or paint with whitewash or white interior latex.
