Young Mountain Ash Trunk Wound: Skip the Paint, Let It Heal

Wound dressings and pruning paints trap moisture and slow callus formation. For a young mountain ash with trunk damage, the best treatment is do nothing but clean the edges.

Proper Care

Gently remove any loose, flapping bark with a sharp knife.
Leave the wound exposed to air.
Ensure the tree is well-watered and mulched.

Young trees compartmentalize wounds rapidly. Within a couple of growing seasons, new bark will roll in from the edges. Paint only hinders this natural process.
