Cold exposure for 30 minutes

(1/1)

smitchell7:
Hey yall. I had a malfunction with my garage door. With my bad luck it had to happen on a day when temperatures were abnormally cold. I had plants exposed to 15F for about 30 minutes before I was able to realize and remotely close the garage door. It quickly heated back to about 65F. Luckily I only have a small portion of my trees in there but I have avocado, loquat, jabo, psidium sartorianum, and a bunch of white sapote seedlings. Are they doomed? They were not in direct wind.

I think you will be ok on most of those if the duration was that short and the heat loss from wind was low.

I left my Cacao out the first night during the Freeze. I had them covered under a sheet but still. So far it doesn't look like I'll lost any. So I don't wouldn't be worried about 30 minutes, especially if you fixed it and brought up the heat. Might see some leaf damage but shouldn't be much.

tip burn at the worst if it was actually 30 mins,

you mean it was 15 outside or it got all the way down to 15 in the garage then you noticed and changed the door?

It was 15F outside and its a huge door so the temp inside most likely got down to 15F pretty fast and stayed like that for 30 min before it closed. Avocado seems to be the only one with damage right now but its too early to tell.
