How can you tell if a tree is water stressed?

Trees signal their water deficit through a number of symptoms. The most common changes in appearance are lighter green to yellow-green foliage, leaf scorch around the margins, wilting
wilting
Wilting is the loss of rigidity of non-woody parts of plants. This occurs when the turgor pressure in non-lignified plant cells falls towards zero, as a result of diminished water in the cells. Wilting also serves to reduce water loss, as it makes the leaves expose less surface area.
