Ash Dieback - Symptoms

Affected trees show extensive dieback of shoot, twig and branches. Trees have often prolific epicormic shoots

  • Black blotches on leaves
  • Affected leaves wilt
  • Small lens-shaped lesions on stems
  • Necrotic spots appear on the bark
  • These spots enlarge forming perennial cankers
  • The infection can girdle the stem
  • Peeled bark reveals brownish/gray wood
  • The tree normally dies

The best time to observe infected leaves is August - September, before the autumn comes along and changes the colour of all the leaves.
