Growing Dicksonia Antarctica in the UK

by Plants for all Seasons 24 Mar 2023 0 Comments

Dicksonia antarctica, commonly known as the Soft Tree Fern or Tasmanian Tree Fern, is a slow-growing, evergreen tree fern native to Australia. It can be grown successfully in the UK, providing a unique and exotic touch to your garden with its large, arching fronds and distinctive trunk. Here are some guidelines for growing Dicksonia antarctica in the UK:

    1. Location: Choose a sheltered spot in your garden with dappled shade or partial sunlight. Tree ferns naturally grow under the canopy of taller trees, so they prefer a location that mimics this environment. Protection from strong winds is essential, as their large fronds can be easily damaged.

    2. Soil preparation: Dicksonia antarctica prefers moist, well-draining, humus-rich soil. Prepare the planting site by adding organic matter, such as compost, leaf mold, or well-rotted manure, to improve soil fertility and water retention.

    3. Planting: Dig a hole that is slightly larger than the root ball of your tree fern. Place the plant in the hole, ensuring that the top of the root ball is level with the surrounding soil. Fill the hole with the soil mixture, gently firming it around the roots. Water the plant thoroughly after planting.

    4. Watering: Tree ferns require consistent moisture, so keep the soil evenly moist, especially during the growing season (spring and summer). During hot, dry spells, water your Dicksonia antarctica deeply and regularly. In addition to watering the soil, it is also essential to water the crown of the fern (where the fronds emerge), as this is where the plant absorbs much of its moisture.

    5. Fertilizing: Apply a balanced, slow-release fertilizer or a liquid feed specifically formulated for ferns in the spring, following the manufacturer's instructions. This will provide your Dicksonia antarctica with the necessary nutrients for healthy growth.

    6. Pruning: Minimal pruning is required for tree ferns. Remove any dead or damaged fronds as needed to maintain a tidy appearance. Cut back the fronds close to the trunk, taking care not to damage the crown.

    7. Winter protection: Dicksonia antarctica is relatively cold hardy (down to around -5°C), but younger plants or those in colder areas may benefit from some winter protection. In autumn, before the first frosts, gather the fronds together and wrap them in horticultural fleece or straw to insulate the crown. You can also add a layer of mulch around the base of the trunk to protect the roots from freezing temperatures.

By Following these guidelines, you can successfully grow Dicksonia antarctica in the UK and enjoy its exotic appearance in your garden. Keep in mind that tree ferns are slow growers, so patience is required. With the proper care and attention, your tree fern will become a stunning focal point in your garden, providing a lush, tropical feel.
