Leaf scorch on maple has many possible causes. Plants that are under stress, such as drought or heat stress, may not provide sufficient water to the leaf margins, causing the edges of the leaves to turn brown and dry. In some cases, scorch may spread to areas between veins or entire twigs may die back. Trees placed near heat-reflecting surfaces, such as buildings or pavement, often suffer from heat stress. Excessive salts from overuse of chemical fertilizers may cause leaf scorch. Scorch may also be a symptom of damage to the roots or stem.

Management Options

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

Non-chemical Management

Select non-chemical management options as your first choice!

  • Irrigate during dry periods. Wet the entire root zone, but do not overwater.
  • Do not overfertilize.
  • Avoid injury to roots and trunk.
  • Soil compaction, which may be caused by heavy foot traffic or construction equipment, can prevent roots from taking up water, resulting in scorch symptoms.
  • Do not plant trees against the sunny sides of buildings or pave over the roots of established trees.

Chemical Management
