Tree mounting Dendrobium antennatum outside in zone 10a?

[Kostas]

Hello!

I would like to mount a Dendrobium antennatum outside in zone 10a and would like to ask you if thats feasible in my zone and if it can withstand temperatures down to 0C or -1C.

Thank you very much in advance!

I would think it would be too cold. Most Dens I know of like 45F - 7C for their winters rest. I wouldn't go below that.

I live in zone 10b and I love mounted orchids, I tried once mounting one on my oak tree but it didn't work, so what I do now is I mount them on a piece of wood like oak, or cork, also i have used coconut halves and they seem to like it, in that way, if t gets cold (that is not every year here in FL) I can bring them inside, maybe you wanna try that method

How often does it get that cold and how long?

Thank you very much all of you for your replies!

spikey,
Thats a great idea for non-hardy orchids but i unfortunately dont live in Pyrgos and so i cant just bring them in before a cold night


It only gets that cold 1-2 nights every winter and only just before sunrise,after which it warms up again fast!

Walter Upton (1989) Dendrobium Orchids of Australia suggests a minimum temp of 15C for Dendrobium antennatum. But he also says they do much better mounted than potted.
