Leaf Spot

Leaf Spot is a common term used for a number of fungal and bacteria-derived diseases that affect the foliage of shade and ornamental trees as well as other plants.

Leaf Spot is identifiable by brownish, but sometimes tan or black, spots that appear on tree leaves. Some spots are raised, shiny, and coal black; others may drop out, leaving ragged holes. Concentric rings could also be present around the spots, and some defoliation may occur. Also see Anthracnose and Black Spot Anthracnose and Black Spot for similar diseases.

Cultural Solutions

  • Leave enough space between plants to allow for proper circulation.
  • Keep foliage dry. Water early in the morning so moisture will evaporate from leaves by nightfall.
  • Remove infected plant parts.
