NotAGreenThumb here with a sad post. All winter I’ve tended my succulent babies and kept the greenhouse at an acceptable temperature. Right here at the end, so close to being warm enough to move back outside, we had a cold snap the weekend after I got home from Florida. A couple of nights with temperatures down to 30 degrees. It’s not arctic weather, but it is below freezing, and it is enough to kill tender succulents if the breaker for the greenhouse heaters trips.
And so it is. Apparently, if it gets too cold, ice crystals will form in the leaves of tender succulents. The leaves will droop, turn black, dry out & fall off. It starts at the bottom and works its way up. The plant will die, and there’s nothing to be done about it. Except hope that new rosettes will form on the base of the stem.
I’m losing between 20-30 succulents, most of them different varieties of Echeveria but also a snake plant and 3 or 4 others.
You can see the leaf damage in this plant.
All three of these beauties are dying.
I don’t know if this snake plant will live. But these leaves were straight before the cold snap.
