Palma - Antarctic Dicksonia


Antarctic Dicksonia is a tree fern native to Australia, Tasmania and some areas of the Arctic; about twenty-five species belong to the genus Dicksonia Antarctica, widespread in Australia, New Zealand and South America. These are very long-lived ferns, which can take on majestic dimensions: growing only a few centimeters per year, the trunk can reach 7-10 meters in height. The thick roots develop a large erect stem, dark brown, which can reach a diameter of 50-60 cm; at the apex of the stem develops a large tuft of fronds, dark green, shiny, evergreen, thick and leathery, arched. The new fronds slowly unroll, and present a thin dark hair. The appearance of the adult plants is very reminiscent of the palm, counting up to 15-20 fronds per stem; the specimens of a few years are generally not very dissimilar from the common ferns: presenting very short stems, only the tufts of fronds are noticed. Specimens grown in a container often do not develop stems.


These ferns that have a palm-like appearance are grown in shady places, especially in regions with very hot summers; generally they do not fear the cold, as long as it is not intense, and the heat, but it is necessary to place them away from direct sunlight and from the wind, which quickly dries the soil. When wanted we can grow the Dicksonia antarctic palm as apartment specimens, in a container.
Especially, in the case of harsh winter climates, it is good to foresee the cultivation of this kind of pot plant, so that it can be placed in a sheltered place during the colder season so that it can be placed in a corner where it can be protected from the rays. solar direct on the hottest days.


The soil around the palm must be kept constantly humid, especially with regard to the young specimens of Antarctic Dicksonia; plants of some years of age, dwelling for a long time, can bear drought without problems, it is advisable to water regularly, especially during the summer months.


In order to see its own specimens of this genus grow in the best way, it is good to grow in soil rich in organic, loose, deep and slightly acidic matter. Then check that the soil allows maintaining the right degree of humidity, if possible, without allowing water to build up.


As with all other ferns, dicksonies develop through spores; only specimens at least 20-25 years produce spores, which can be sown at any time of the year, in a place sheltered from the cold. once the new plants have acquired the necessary strength, it will be possible to place them permanently.
