Re: Mild late winter/early spring gets the Dicksonia antarct
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
Best regards

Re: Mild late winter/early spring gets the Dicksonia antarct
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.fern Rob wrote:Picture 3 looks like it is narrowing.Tom2006 wrote:None of mine have ever narrowed, but then again I lost all my older ones.

Most wanted list - Any Young Trachycarpus and/or fern.

Re: Mild late winter/early spring gets the Dicksonia antarct
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.Tom2006 wrote:I bought the fern in picture three in 2011.

Re: Mild late winter/early spring gets the Dicksonia antarct
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 Either way, producing the dome shape with the emerging croziers at the top seemed to help on mineDave Brown wrote:The problem is when they chain saw the fronds off including those almost upright.

Re: Mild late winter/early spring gets the Dicksonia antarct
I wonder if I was to cut the Dicksonia antarctica from inside of the crown outwards if that would retain its shape better.

Re: Mild late winter/early spring gets the Dicksonia antarct
I always do it from underneath. Pulling the frond down until as much of the stipe is visible, then snip at that point.fern Rob wrote:I wonder if I was to cut the Dicksonia antarctica from inside of the crown outwards if that would retain its shape better.

Re: Mild late winter/early spring gets the Dicksonia antarct
Thanks for that, I will do that if the weather improves.
Re: Mild late winter/early spring gets the Dicksonia antarct
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

Re: Mild late winter/early spring gets the Dicksonia antarct
The new fronds push the old dead ones outwards.

Re: Mild late winter/early spring gets the Dicksonia antarct
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.fern Rob wrote:In nature their crown would not be a sunken
