Blue Ice Arizona Cypress problems — and how to fix them
Blue Ice Arizona Cypress (Cupressus arizonica 'Blue Ice') 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.
Seiridium canker
Fungal cankers cause branch dieback in wet conditions. Prune out infected wood promptly; avoid overhead irrigation. Most common in humid climates.
Root rot in wet soil
This species cannot tolerate waterlogging. Plant only in very well-drained positions; avoid heavy clay soils entirely.
Cypress aphid (Cinara cupressi)
Large, brown aphids cause yellowing and death of shoot tips. Treat with systemic insecticide at first signs in spring.
Wind rock on young trees
Fast-growing young trees need firm staking until well established. Check stakes regularly.
