How to Care for a Dicksonia (Tasmanian Fern)

Caring for Dicksonia: how to enjoy this tropical eye-catcher to the fullest

The Dicksonia antarctica , also known as the Australian tree fern, is an exotic specimen that instantly gives your garden a tropical look. With its robust trunk and graceful, bright green fronds, it's one of the most beloved ferns among gardeners. But how do you keep this tropical beauty healthy and beautiful? This blog post covers all the important aspects of Dicksonia care, and we'd also like to refer you to our outdoor plant collection and the dedicated Dicksonia page.

1. Location: shade or partial shade

The Dicksonia doesn't like direct sunlight. Ideally, choose a spot in (partial) shade , where the plant is protected from the hot midday sun. It feels right at home under a tree or in a sheltered corner of your garden.

2. Watering: keep the trunk moist

A unique characteristic of the Dicksonia is that it absorbs water not only through its roots, but also through its trunk. Therefore, water the trunk and the pot/soil regularly. This is especially essential on warm days or during dry spells. The soil should always be slightly moist, but ensure good drainage to prevent water retention.

Pro tip:

Use rainwater if possible — softer water is better for ferns!

3. Dicksonia in pot or open ground

This fern grows well in a large pot, as long as you provide sufficient root space and ensure good moisture retention. It thrives even better in the ground, especially in a sheltered spot with humus-rich, moist soil.

4. Protect from frost

Although the Dicksonia is surprisingly cold-resistant, frost protection is essential . At temperatures below -4°C, it's best to protect the trunk and growth center with straw, leaves, or a special fleece. In a pot, you can also temporarily move it to a cool, frost-free spot during the winter.

5. Fertilize for vitality

During the growing season (spring and summer), regularly feed the Dicksonia with fern fertilizer or organic food. This encourages leaf development and keeps the plant healthy and vigorous.
