Troubleshooting
Soft Tree Fern problems — and how to fix them
Soft Tree Fern (Dicksonia antarctica) 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.
Crown or trunk drying out
If the growing crown dries the whole plant can die, even when the soil looks damp. Water directly into the crown and keep the fibrous trunk moist at all times.
Frost damage to the crown
Hard frost kills the central growing point. In cold areas pack the crown with straw or fleece over winter and protect the trunk top.
Frond scorch from sun or wind
Brown, crisped fronds come from too much sun, low humidity, or exposure. Move to sheltered dappled shade and raise humidity.
Very slow growth misread as decline
Trunk extension of only a few centimetres a year is normal, not a problem. Patience and steady moisture are key; do not over-fertilise to force growth.
Prevent soft tree fern problems before they start
Most soft tree fern issues are care-mismatch, not bad luck. Dial in the basics:
