Everyone is urged NOT to do any outdoor burning. In fact, many Texas counties have burn bans currently in effect. Water deficits in trees have an adverse effect on many of the tree's growth processes. Severe water stress will injure trees and may kill them. In addition, stressed trees are more vulnerable to insect and disease pests when compared to a healthy tree.
Hardwood trees display numerous symptoms related to water stress.
Wilting of leaves is a common indication of water stress. Wilting can be classified as incipient, temporary, or permanent. Incipient wilting is not readily noticeable, but it can change to temporary wilting which is characterized by visible drooping of the leaves during the day. At night the plant will rehydrate and recover from temporary wilting. During prolonged dry periods, temporary wilting can change to permanent wilting where the plant does not recover during the overnight period.
