Even though the stresses are described on maples, they do occur on other trees. The procedure for prevention or care would be the same for other shade trees. This may lead to scorch caused when leaves lose water more rapidly than moisture can be replaced from the soil. This can be caused by too little water in the soil or a physical restriction of the root. Usually the symptoms appear during hot, dry, windy weather.
Trees growing along streets or in areas where the roots are restricted seem to suffer most.
Scorch itself seldom kills a tree, but may weaken it to the point where insects or disease can further injure it. Leaf scorch is best controlled by deep watering during dry periods. Also, an early spring application of fertilizer containing large quantities of potash, which stimulates root development, has been found to be helpful. If scorch is severe early in the season, a judicious pruning will help increase the supply of water to remaining leaves. This problem occurs when a root entwines around another large root or the base of the tree and prevents or hinders water and nutrient movement.
