australian tree fern
By Beachbums
United Kingdom 
I have an australian tree fern which does very well, but when I cut the fronds off at the ned of the season the opening for next years growth is getting smaller each time, consequently the fronds are smaller each year. Is this normal? Any suggestions!!!!

I leave the fronds on over winter, only cutting off as new growth comes through. Ours respond well to tree fern fertilizer every few weeks in the summer

Why not let mother nature take care of it.
Let it run wild for a couple of seasons.
