If trees have to be removed, the tree should be cut and removed from the site without delay. Grind stumps after the tree is removed or cut the stump very low to the ground. Do not damage the trunks of trees during lawn maintenance operations. If additions are made to a home, protect the root system of pines during the construction. Do not allow cement trucks or other heavy equipment to run repeatedly over the root zone of the tree.
Water is especially important during periods of drought.
