Troubleshooting
Blue Surprise Cypress problems — and how to fix them
Blue Surprise Cypress (Chamaecyparis lawsoniana 'Blue Surprise') 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.
Faded blue colour
Insufficient sun. Plant in full sun to maximise the silver-blue cast.
Root rot and dieback
Lawson cypress is susceptible to Phytophthora in wet soil; ensure sharp drainage and never overwater.
Browning foliage
Drought or drying wind. Maintain even moisture and shelter from desiccating exposure.
Open, leggy form
Too much shade or lax feeding. Site in full sun and avoid heavy nitrogen to keep the cone tight.
