Troubleshooting
California Nutmeg problems — and how to fix them
California Nutmeg (Torreya californica) 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.
Wind and drought stress
The most common failure in cultivation. California Nutmeg requires shelter from cold, drying winds and consistent soil moisture. Brown, crisping needles indicate desiccation. Site in a sheltered position and mulch deeply around the root zone.
Slow establishment and transplant shock
Extremely slow-growing and sensitive to root disturbance. Plant from containers into prepared, humus-rich soil; water consistently for the first three seasons. Avoid moving established plants.
Scale insects
As with related Torreya species, armoured scales can infest stems and the undersides of needles. Monitor in spring; treat crawlers with horticultural oil or a systemic insecticide if populations are high.
