Troubleshooting
Norfolk Tree Fern problems — and how to fix them
Norfolk Tree Fern (Cyathea brownii) 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-damaged fronds
The exceptionally large fronds are highly susceptible to wind tearing. Position in a sheltered spot protected from prevailing winds. Wind-damaged fronds cannot recover; remove and allow new croziers to unfurl.
Slow establishment
Transplanting large tree ferns can be stressful. Keep the trunk wrapped in hessian and misted for months after planting. Ensure roots are kept consistently moist until the plant is established and producing new fronds.
Frond tip browning
Caused by low humidity, under-watering, or salt build-up from tap water. Flush soil periodically, switch to rainwater if possible, and maintain humidity above 65%.
