Re: Cyathea a cooperi
Strong plant Kev, I have already said it once, normal this temperature is the death blow, especially if it is so cold all night!

Re: Cyathea a cooperi
Something about croziers on Tree ferns that's almost- I don't know,cute? Like Teddy Bear ears or something.

Re: Cyathea a cooperi
February is historically our coldest month this fern needs to stop growing now today's 14c will not help with that fact though

Re: Cyathea a cooperi
I think that fern is having an identity crisis!

Re: Cyathea a cooperi
Quite remarkable! I wonder if it might actually be that other cooperi-a-lke that was doing the rounds a few years ago (but never quite made it to SE Essex!). Steve Pope had it, for example.

Re: Cyathea a cooperi
Amazing cooperi! Mine are tucked up in the polyhouse dreading the forthcoming cold spell. You're not leaving it out are you Kev?

Re: Cyathea a cooperi
Yes indeed Tom it's probably been outside over 10 years now 2 croziers are pushed up against the plastic cloche it's under

Re: Cyathea a cooperi
My cooperi was out unprotected and got -4, some slight damage on one leaf but that's it so far, its doing much better than the Australis which is going to lose most of its leaves,

Re: Cyathea a cooperi
Mark you must have your fern in a good microclimate as -1c burns my leaves and the next freeze brown's them all off. Mine is still growing but I think this next week will kill the new croziers.

Re: Cyathea a cooperi
Well i didnt leave it out through the current freeze, i chickened out, put it in the greenhouse. The -4C burnt a few leaves and killed of a developing crozier, but otherwise seems ok. It wasnt out the whole winter, just jan/feb up until the beast from the east which i figured was going to do it some serious damage or even kill it.
The rest of the winter our freezes had been very short lived (a few hours) and maybe that helped. I also put the australis in a cold frame, but it looks rough. Antarctica also looks rough it was out unprotected.
Not sure what to make of my two squarrosas, the leaves that are left look unburnt, but otherwise the plants look dormant like a typical UK fern, tightly coiled up brown croziers waiting to sprout!
