why has healthy green leaves fell off my orchid

[orchiddream]

, can you please help, I have approx. 20 phals in my porch and within a week the leaves have started falling off, even healthy green ones, there roots are healthy and there is no black so cant be crown rot. I think its the cold but not sure. here in the uk its cold at the minute and my porch has no heating, will it be the temperature? I have moved them upstairs in my hall now hoping for a miracle. some other leaves are limp and red too, please help.

Pictures will help us help you.

By the way, when phals are it by cold, the whole things in severe case just collapse like a piece of mushy junk. lol

I've never seen healthy green leaves just fall off.
hmmm

You're in the UK? It's the cold. Their environment should be >65°f/18°C.

thanks for the reply, is there any chance of them surviving. I have put them where it is a warm environment now. its my own daft fault I should have done it sooner, instead I wanted them to be seen as they looked so lovely in the entrance of my porch.

Can you post a photo of what they look like now? It's a bit difficult to guess whether they'd recover otherwise.

It is happening to mine now as well. Can anyone identify the cause?

Might be too wet + the cold.

What are the temperatures like there?

It is around 12 to 24 degree celsius. I just water them before taking those photo and i only water them thoroughly every 2 weeks. It happened very sudden.

12 C (53.6 F) is a bit too cold. Shoot for 60 F - 95 F (15.6 C - 35 C). It should really be no cooler than 55 F (12.8 C), but 60 F (15.6 C), on the low end is more ideal.

Same question…

How is the temperature?

Many Phals should be grown no cooler than 55 F (12.8 C). The ideal temperature range is 60 F - 95 F (15.6 C - 35 C).
