About Tasmanian tree fern
Dicksonia antarctica, also known as the soft tree fern, is a majestic perennial fern that develops a robust, fibrous trunk, culminating in a crown of large, elegant fronds. Its prehistoric and lush appearance makes it an impressive centerpiece for shady gardens, cool patios, or as an accent in wooded and humid landscapes. It brings a unique texture and a tropical touch to any outdoor setting or even very spacious and bright indoor environments.
Native range
Southeast Australia and Tasmania
Care tips
It prefers partial to full shade, protected from direct sun and strong winds, which can scorch its fronds. Watering should be abundant and consistent, especially on the trunk and crown, keeping the substrate always moist but not waterlogged. It needs an organic-rich, well-drained, and slightly acidic substrate. A common mistake is allowing the trunk to dry out completely, as the plant absorbs water through it.
How to save a dying Tasmanian tree fern
- Warning signs
- Dry, brittle fronds, soft or sunken trunk apex. Trunk appears to shrink.
- First aid
- Water trunk and crown daily with rainwater/distilled water, maintain high humidity. Protect from direct sun and winds.
- What kills it
- Dryness of trunk or crown, exposure to direct sun or frost. Lack of constant ambient humidity.
- Can it be saved?
- Yes, if the trunk is still firm and the crown is not rotted. Recovery is slow but possible with intensive care.
