The source says: it is among the most commonly damaged plants.

When to look

Spring – fall

How to protect

  1. Prevention
    • Do not overdo nitrogen.
    • Remove late secondary blossom.
    • Disinfect tools between cuts.
  2. By hand from 2 weeks after flowering until the end of summerCut affected shoots 11¾ in (larger branches 23½ in) below the visible damage, into healthy wood; disinfect tools.
