Dicksonia Antarctica, also known as the ‘Soft Tree Fern’ and holder of the prestigious RHS Award of Garden Merit, is a large, evergreen fern that is native to Australia and New Zealand. The plant is known for its distinctive, soft fronds and is often used as an ornamental plant in gardens and landscaping. The plant is also commonly called “Australian Tree Fern” or “New Zealand Tree Fern” and it is the only Dicksonia species found in the wild in Australia.

The plant can grow up to 4 metres tall. The fronds are soft to the touch, dark green in colour and feathery in texture. The trunk of the plant is covered in a thick, brown, fibrous layer that protects the plant from fire and other environmental stressors.

In the wild, Dicksonia is typically found growing in moist, shady areas, such as in the understory of rainforests. However, it can be grown in a variety of environments and is adaptable to different soils, including clay, loam, and sandy soils. The plant can tolerate temperatures down to -5°C.

How to care for your Dicksonia Antartica

  1. Light: Dicksonia antarctica prefers partial to full shade, but can tolerate some sun. It is best to plant the fern in a location that receives morning sun and afternoon shade.
  2. Water: Dicksonia antarctica prefers a moist, well-drained soil. Water the plant regularly and make sure the soil does not dry out completely. However, make sure to avoid over-watering, as this can lead to root rot.
  3. Fertilizer: Dicksonia antarctica does not require a lot of fertilizer, but it can benefit from a slow-release fertilizer applied once a month during the growing season.
  4. Pruning: Dicksonia antarctica does not require frequent pruning, but it can be pruned to shape and control its size. Prune the plant after it flowers, and avoid pruning in fall or winter.
  5. Soil: Dicksonia antarctica prefers well-drained, moist soil with a pH of 6.0 to 7.0. If your soil is heavy clay or sandy, amend it with organic matter to improve drainage.
  6. Humidity: Dicksonia antarctica likes high humidity and it will perform best in a humid environment. Mist the plant’s fronds regularly, especially during dry weather, or set the pot on a tray of wet pebbles.
  7. Temperature: It is half hardy down to -5°C  so will need Winter protection in colder temperatures.

By following these care tips, you can ensure that your Dicksonia Antarctica thrives and remains healthy for many years to come.
