Use IPM (Integrated Pest Management) for successful plant problem management.

Biology Leaf scorch and leaf roll are results of stress. Leaf scorch is characterized by browning of the tips and margins of the leaves. Leaf roll is a puckering and upward rolling of the leaf along the midvein. The undersides of rolled leaves are often pinkish or purplish. Drought, heat stress, overwatering, and construction damage are possible causes of both problems. Leaf scorch can also be caused by over-fertilization. Similar symptoms can be caused by herbicide damage.

Management Options

• Avoid compacting soil, which inhibits water penetration into the soil and reduces drainage.
• For more information see EB 1422, Leaf Scorch of Shade Trees.
• Overfertilization can lead to salt injury on leaf tips and margins.
• Overwatering and underwatering can both cause leaf scorch.
• Provide proper irrigation and fertilization for your plants, especially during dry weather.
• Try to prevent injury to the roots and trunk, especially during construction or soil excavation.
