Troubleshooting
Ellwoodii False Cypress problems — and how to fix them
Ellwoodii False Cypress (Chamaecyparis lawsoniana 'Ellwoodii') 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.
Stems splaying open
Snow load or heavy growth bends the columns apart. Tie in loosely or shake off snow; tight pruning encourages density.
Brown patches in foliage
Often drought stress or Phytophthora root rot, to which Lawson cypress is prone. Ensure excellent drainage.
Loss of blue colour
Too much shade. Site in full sun for the strongest silver-blue tint.
Sudden whole-plant dieback
Phytophthora root rot in wet soil. Avoid replanting cypress in the same spot; prioritise drainage.
