Troubleshooting
Himalayan Cypress problems — and how to fix them
Himalayan Cypress (Cupressus torulosa) is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Cold damage
Only moderately hardy; foliage browns and shoots die back in hard frosts, so site in mild, sheltered gardens.
Coryneum canker
Resin bleeding and branch dieback can affect stressed trees; prune out infected wood and avoid drought stress.
Root rot in wet soil
Yellowing and decline on poorly drained sites; plant only where drainage is good.
Thin crown in shade
Foliage opens up and looks sparse without enough sun; give it a bright, open position.
