Signs of Ash Tree Infestation or Disease

Identifying signs of infestation or disease in your ash tree is crucial to maintaining its health. Here are common indicators to watch out for:

  • Sparse Canopy: If you notice thinning leaves or dead branches in your ash tree’s canopy, it could be a sign of infestation or disease. This can indicate stress affecting the tree’s overall health.
  • Unusual Bark Changes: Look for cracks, splits, or unusual patterns on the bark of your ash tree. Changes in bark texture or color may signify the presence of pests or diseases.
