completely frozen succulent

Post by Barrason »

I have some sedeveria letzias that are completely frozen solid. They've been in below freezing temperatures before, but not for this long as the temperatures are struggling to get above freezing now. I've brought them into a cool room (12C) Also, the leaves on the smaller plant seem to be falling off easily.

What a pity. I'd be very surprised if they survive.

You'd be surprised at how tough these are. They survived down to -12c in February 2021. Difference then is that the greenhouse got above freezing during the day as the February sun is stronger, and that they had gone longer without water. I do have another small Sedeveria Letzia that somehow isn't frozen and looks normal, but I think that one is more dehydrated.

I'm asking if it will survive. Here it what it looks like now.

When you moved the plant into the cool room, was there condensation on the leaves and/or the soil? In my opinion the plant could survive, if kept completely dry.

Yes there was condensation initially on the leaves as the plant was thawing out, but now it's completely dry.

All you can do is wait.
If it were me. If there any leaves that seem solid,I would pluck a couple. Also it looks like you already had a couple laying on the soil.
If the plant doesn't make it,odds are some of the leaves will sprout and you can grow new ones from the leaves. Just set them on some co co coir or peat and see if they sprout.
But I believe the parts that were frozen might turn to mush,and the "mush" has a good chance of spreading. Which is my reasoning behind plucking a few leaves that seem solid.

The leaves are fairly firm on the larger plant however there are lots of dark marks and some leaves look wrinkly. The smaller plant had lots of soft leaves but no brown marks hower the growing tip leaves are still firm on the smaller plant.

Roots could be a problem if the root ball got frozen.

Unfortunately the smaller plant had died as the tip was brown and the stem was rotten. The larger one still looks okay at the tip but with substantial leaf loss.
