Troubleshooting
Silver Tree Fern problems — and how to fix them
Silver Tree Fern (Cyathea dealbata) 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.
Frost damage
More frost-sensitive than Dicksonia species. Protect the crown and trunk with fleece in any frost. Even brief frost exposure can kill the growing tip, from which the plant does not recover.
Silver coating fading
The silver underside of fronds is a natural feature of new growth. Older fronds lose this as they age. Ensure good indirect light and consistent moisture for the best frond production.
Trunk desiccation
The trunk must remain moist. In hot or dry weather, soak the trunk directly with water in addition to watering the soil.
Wind scorch
Large fronds are vulnerable to desiccating winds. Plant in a sheltered position or use windbreaks. Brown frond margins may indicate wind damage.
