The problem is when they chain saw the fronds off including those almost upright. As the stipes harden in the upright position they don't move out as the living stipes would have done. That is what restricts the new croziers from emerging properly. I pull the stipes sideways and cut off as close to the base as possible which allows mover emergence room :wink:

I bought the fern in picture three in 2011. The bottom of the robin's feet was where the first flush came from so you can see its growth since then and how the old fronds are pushing out. That said, I will keep an eye on it. icon_thumleft
Most wanted list - Any Young Trachycarpus and/or fern.

I thought that may have been the case with Dicksonia antarctica.

I think I have a problem with one of my old Dicksonia antarctica as the crown is nearly non exsistant, I think I will be working on the Dicksonia antarctica tomorrow.

Of course it could be that having had all it's fronds and root system cut off it doesn't have the energy to push the old stipes open :wink: Either way, producing the dome shape with the emerging croziers at the top seemed to help on mine :wink:

I wonder if I was to cut the Dicksonia antarctica from inside of the crown outwards if that would retain its shape better.

I always do it from underneath. Pulling the frond down until as much of the stipe is visible, then snip at that point. :wink:

I have a feeling this has probably already been explained, but can't quite get my head round the answer so a 'dummy's guide' might be needed! Each year my Dicksonia antarctica sends out fronds from a circle within last year's. Therefore will there not come a time when there physically isn't enough room for many/any fronds to emerge? How do you get it to start sending them up from the outer edge again?

Think of it as a Yucca, Agave or Palm. It grows in exactly the same way :wink:

The new fronds push the old dead ones outwards.

It is not sunken on ours either. it is the last flush of fronds were still almost upright when chainsawed off, and once cut the stipes don't move outward, just leaving a flat plate above the crown.
