Troubleshooting
Alerce problems — and how to fix them
Alerce (Fitzroya cupressoides) 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.
Heat and drought stress
It is poorly suited to heat and dryness and browns or declines under stress. Grow only in cool, wet maritime climates with constantly moist, shaded roots.
Low humidity decline
Dry air scorches the foliage and weakens growth. Provide a sheltered, humid microclimate and avoid hot, exposed, windy sites.
Slow establishment
Seedlings and young plants grow slowly and are sensitive while settling. Keep steadily moist, sheltered, and lightly shaded for the first years.
Conservation sourcing
Alerce is internationally protected and threatened, so wild material is illegal to trade. Buy only nursery-propagated plants from reputable sources.
Prevent alerce problems before they start
Most alerce issues are care-mismatch, not bad luck. Dial in the basics:
