Cyathea still growing!!
Cyathea still growing!!
I have been checking on my Cyathea (small cooperi and a larger 10" trunked Medularis) and to my surprise they are very slowly STILL putting out fronds. It has to be said, this is in my heated polyhouse, but I'm talking heating at just above freezing point so I am amazed there is any growth at all. Not that I am complaining, but just curious to know if this is normal?
Most wanted list - Any Young Trachycarpus and/or fern.
Re: Cyathea still growing!!
I have a Cyathea in a conservatory which is kept above 10*c and that one is growing very well.
When they ship tree ferns over from Australia they are refrigerated to stop them growing (2*c).

Re: Cyathea still growing!!
Tom, mine haven't stopped at all ,albeit at a very much slower rate. Even a D.A. has put a new frond out....
Re: Cyathea still growing!!
It’s not too surprising when you consider they come from cool mountainous areas!
Active growth will start slowly at about 5c and when temps get to 10-15c that’s an ideal growing temperature for most of these tree ferns.
Because the Cyathea have started growing they will be using up water though… so make sure the potting compost doesn’t go dry on them, that’s a big killer for Cyatheas.

Re: Cyathea still growing!!
From what I have read tree ferns grow best at 25*c. Most websites state this and it has been my expierience from seing a medullaris in a heated conservatory. 10-15*c is a severe underestimate, these are subtropical plants, 10-15*c is their winter temperature. Though trying to keep the humidity up over 80% indoors with the temperature around 25*c can be a challenge.

Pdid that C cooperi looks healthy for this time of year, ow do you look after it

you can see it's in a conservatoryfern Rob wrote:Pdid that C cooperi looks healthy for this time of year, ow do you look after it

Re: Cyathea still growing!!
As said it`s in a conservatory gobbling up loads of water kept between 10 and 20 deg. And it`s a Brownii BTWfern Rob wrote:Pdid that C cooperi looks healthy for this time of year, ow do you look after it
Re: Cyathea still growing!!
It looks just like my C cooperi, what is the difference between them.
My cooperi was in the conservatory but I could not get it to grow like that.

Re: Cyathea still growing!!
Taken from http://www.forestferns.co.uk/tree-ferns ... ea-browniiCyathea brownii is very closely related to Cyathea cooperi although differs slightly in appearance. The hairs covering the stipes on Cyathea brownii are a sandy colour and dense whereas with Cyathea cooperi the hairs go from dark at the base to a lighter brown. The other difference is that Cyathea brownii grows to be a lot bigger, possibly the largest tree ferns species in the world. Botanists think that the reason for these subtle differences are down to evolution.
It`s taller and blonder.

Well my cooperi which was a direct import from Australia is identical and is sandy coloured from top to bottom of the leaf base.pdid wrote:Taken from http://www.forestferns.co.uk/tree-ferns ... ea-browniiCyathea brownii is very closely related to Cyathea cooperi although differs slightly in appearance.

I'm not sure now

If you read what I have said again! (Active growth will start slowly at about 5c and when temps get to 10-15c that’s an ideal growing temperature for most of these tree ferns)
I’m tying pointing out that past… 10-15 degrees, most Cyathea will resume a normal rate of growth!
I haven’t talked about optimum temperatures or specific species.
In the wild most Cyathea never go dormant because temps don’t get lower then 10c... there in active growth all year round!!
