This evergreen Australian tree fern has large fronds and a dark brown trunk - slow growing to 3m/10ft or more. It should be planted in a moisture retentive soil in a cool shaded position out of strong winds. It can also be grown in a cool shaded conservatory if preferred.
Larger specimens are able to stand temperatures as low as -10°C but in very cold areas the crown should be protected with a mulch of bracken or straw. In every case, the tree fern should be watered freely, especially in warm weather.
We always advise feeding antarcticas with a high nitrogen liquid feed — on the fronds and trunk of the fern from mid-spring to mid-summer, in order to encourage green frond growth. This is because it is unable to absorb nutrients at the base of the trunk in the same way as the other Dicksonia varieties - it is the top foot of the tree fern that is alive and able to take in all the goodness it requires.
Our antarcticas in 15ltr pots are for sale in our online shop at £40.00. They have around 6-12 inches of trunk and 2ft of foliage.
They are also available in varying sizes at the garden centre - priced per footage of trunk, ranging from £25.00 per half foot and £40.00 per foot.
