How tall do Dicksonia antarctica grow?

How tall do Dicksonia antarctica grow?

These ferns can grow to 15 m (49 ft) in height, but more typically grow to about 4.5–5 m (15–16 ft), and consist of an erect rhizome forming a trunk.

How can you tell a Dicksonia Antarctic?

Dicksonia antarctica is most easily distinguished from the Cyathea species by its smooth stipe bases covered in hairs rather than scales, the fibrous matted roots which soon cover much of the trunk and the marginal, 2-valved soral structure.

How fast does Dicksonia antarctica grow?

about 1-2 inches per year
Dicksonia antarctica are really slow growing, only gaining about 1-2 inches per year in trunk height. A mature plant, with only 2 ft of trunk, can take 25 to 30 years to grow!

How deep should you plant Dicksonia antarctica?

Plant the trunk about 15cm deep or if it has a taller and heavier trunk, then plant the trunk sufficiently deep in the soil for this to be stable and not moving once planted in the ground or in a pot.

Do Dicksonia antarctica have roots?

Dicksonia Antarctica are surface feeders and will benefit from adding a deep mulching of leaf mulch and bark chips around the base of the plant. They have extensive root systems in the soil. If a Dicksonia is to thrive and produce good sized fronds (8 – 10 ft.

Can you cut a tree fern in half?

It cannot be cut in half. You recognise a Cyathea or the rough tree by these prickly hairs that are at the bottom of the fronds. And they are totally different than the soft tree fern, the Dicksonia, as this one is, because this one has no prickles or hairs down the base of those fronds at all.

How long do tree ferns live?

The tree fern species in this study can grow to over ten metres in height [15] and have been estimated to live more than 500 years [13], while other species in Australia have been recorded growing in excess of 15m, including the Norfolk Tree Fern, Cyathea brownii, which can grow to 20m [16].

Can you cut a tree fern in half and replant?

You can just chop it and transplant it and new roots will grow. And the reason that that’s going to work is because this whole trunk is a root system and wherever I cut through and plant it, it’s going to grow a new root ball around it.

Do tree ferns need big pots?

Tree ferns prefer a neutral to slightly acid soil, so pot in an ericaceous compost. The container does not need to be too large for growth, but it needs to be large enough, and heavy enough, to support the plant.
