More about this problem

What you will see

Branches or tips turn yellow and brown. Sunken reddish cankers with resin ooze, the wood beneath is reddish-brown. The whole plant may gradually die.

The source says: the fungus only occasionally damages it.

How to protect

  1. Prevention
    • Do not plant in drought and stress; allow sufficient spacing and good drainage.
    • Disinfect tools; spores spread on tools, by water and wind, and on planting material.
    • Choose less susceptible species.
  2. By hand all year, in dry weatherCut back affected branches to healthy wood and disinfect the cuts. Fungicides are generally ineffective.
