ferns in pots
you let me know if there are any native tree ferns I could grow
in a container? How big would the container need to be?
Zealand has two genera of tree ferns, Dicksonia (including
wheki) and Cyathea (including ponga). You could grow most
of the native tree ferns in containers in their early stages, but
I am assuming you want to grow one for a decent period of time.
Most of the tree ferns end up enormous and have huge fronds.
However, you could get
away with growing a species of Dicksonia for quite some time
in a relatively small tub. I recommend either Dicksonia squarrosa
(wheki) or Dicksonia fibrosa (wheki-ponga). Both of these
require peaty, damp soil with summer watering, semi-shade at least
to start with, and protection from wind. Both species will eventually
reach 7 metres in height, but this will take some time. I suggest
a large container of at least a metre in diameter to start with,
and pot on as needed. They are usually widely available from most
