Troubleshooting
Boulevard Cypress problems — and how to fix them
Boulevard Cypress (Chamaecyparis pisifera 'Boulevard') 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.
Interior browning
Drought, alkaline soil or stress browns the dense inner foliage; keep roots evenly moist in acidic, well-drained soil and mulch to conserve moisture.
Spider mites
The soft foliage is mite-prone in hot, dry conditions; rinse plants, raise humidity and treat heavy infestations with horticultural oil.
Loss of blue colour
Shade and overly rich feeding dull the silver-blue; site in full sun and use moderate, balanced fertiliser to keep the colour strong.
Root rot in wet soil
Waterlogged ground rots roots and yellows the canopy; ensure free drainage and never leave containers standing in water.
