Long term drought can be devastating on landscape and woodland trees. An environmentally stressed tree must expend additional energy to survive. Extremes of drought leads to decreases in trunk diameter and height growth, declining resistance to pests and diseases, less food production via photosynthesis, and in flower and fruit production. Symptoms of drought stress include wilted […]

This practice, also called “topping”, reduces tree (or shrub) height. Over 25 years, Southern Living magazine called this “crape murder”. Crape murder is not going away. More crape […]
