Dicksonia antarctica (Tasmanian Tree Fern) - This is a slow growing tree fern that in time will reach 15 feet tall with a possible 6-10' spread. It is slower and shorter than Cyathea. Many arching fronds are divided into many small toothed leaflets giving the tree a full head. The trunk of the tree is covered with soft reddish-brown hairs. It does best in shade, but can be planted in sun in the foggy coastal areas. Plant in a well-drained soil and water regularly and increase to watering frequently during hot weather. Irrigation can be applied to the trunk as well as the surrounding soil but avoid watering the crown as this enhances conditions that promote diseases such as Rhizoctonia or Tip Blight (Phyllosticta). Tip blight has become a more prevalent disease of tree ferns in southern California and seriously disfigures the new growth and older foliage. This tree fern is hardy and evergreen to the mid 20's but can defoliate and resprout after prolonged temperatures down to at least 19 F.  The information provided on this page is based on research we have conducted about this plant in our nursery's library, from what we have found about it on reliable online sources, as well as from observations in our nursery of crops of this plant as well as of plants growing in the nursery's garden and those in other gardens. We will also incorporate comments received from others and welcome getting feedback from anyone who may have additional information, particularly if it includes cultural information that would aid others in growing  Dicksonia antarctica.
