I have both of the tree ferns and palm you mention ( no olive tree).
Cyathea australis is I believe as hardy as Dicksonia Antarctica
All three appear quite happy outside in winter (West Yorkshire ).
The tree ferns loose their fronds with heavy frost but with a small degree
of protection (fleece ) the fronds will survive at least another year. The
old darker green fronds make a good contrast with the new ones. At the
least
protect the crown with a handful of straw or leaves.
My Phoenix canariensis planted in a windy well drained soil is as tough as
old boots and looses the odd lower branches only


How old/established are your ferns?

4 Tree ferns. Three have trunks about 5 feet and are planted in the ground.
One in a pot at about 2 feet high.

All four have been in my possession for about 6 years

Thanks for you reply. Which varieties to you have?
