Troubleshooting
Candlenut problems — and how to fix them
Candlenut (Aleurites moluccanus) 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.
Toxic raw nuts
Raw kernels are strongly purgative and irritant; they must be roasted before any culinary use, and fallen raw nuts should be cleared away from children and pets.
Frost sensitivity
Strictly tropical and frost-tender; it cannot tolerate cold and is killed by frost, restricting outdoor growing to warm, frost-free climates.
Weedy self-seeding
In suitable climates it seeds and spreads readily and is considered invasive in some regions; site it where volunteer seedlings can be managed.
Brittle wood and limb drop
Fast growth produces relatively weak, brittle branches prone to breaking in storms; site away from buildings and prune to maintain sound structure.
Prevent candlenut problems before they start
Most candlenut issues are care-mismatch, not bad luck. Dial in the basics:
