Well, they might rebound.

I froze a couple Jades on accident, and they have slowly recovered from the stumps.
The key is to check the roots and make sure that they are healthy and sufficiently dry.
You don't want moist soil around compromised roots. I removed all the old soil and
put my Jades into a mix of mostly Perlite to recover. All the limbs fell off, until the
plant had only a viable trunk remaining. I've included a link of the process below.

I'd just let the Hoya do its thing. Give it warmth and appropriate light.

Watch the Adenium for mush or softness and be prepared to excise any rot.

Good luck.

Sherri,

If the soil wasn't wet your plants should be OK. If they were in wet soil, it can be touch and go, so depot your plants out of their wet soil and set them aside to dry for a few days.

Thanks Josh I feel much better. Mine was not nearly as bad as yours. Glad to see yours came back. I left almost all my potted plants out that nite. Most off them are all stem/trunk, but I think they will recoup.
I will check the roots like you said and put off watering, til I see new growth.
I sat on the floor with tears in my eyes, a wlamart bag and scissors in my hands yesterday. I may loose a few but not as many as I thought.
Temps are suppose to be back in the 80's this week, so I guess it will be safe to drag them back out and let the healing begin.
Thanks again,
Sherri

catusmcharris, Thankfully the soil was dry.I think that added to the fact that no more damage had been done. They looked alot worse than they were. Once I got them cut back it was not as bad as I thought. Thanks for the advise.Even though they are mostly sticks with no leaves I think they will be ok. Only a couple are iffy.
