Aloes produce many pups during a good growing season. Last summer I re-potted dozens of pups into larger clay pots. I like to put pea gravel on top of the sandy potting soil.
I had about two dozen good sized baby aloes that I planted in clay pots ranging from 6″ to 10″. I put them in the greenhouse before the first frost, back in October. We had a second polar blast a week ago. The first blast gave us 20 degree nights. My aloes made it thru the nights with just a coal oil lamp burning a low flame all night. This past blast, however, gave us two nights with nine and eleven degree nights. That was just too much for the aloes.
All aloes that partially survived were right next to the lamp. Other groups of pots, about two to three feet away fro the oil lamp completely froze.
This once beautiful and now frozen and dead aloe had several pups.
The core of this frozen aloe might be alive. Hopefully only the outer leaves froze. If the core is still alive, it might re-grow.
The outer edges of these thick, large leaves froze. I expect the leaves to partially decay, maybe not, but probably. These large leaves were thick enough that they did not freeze completely thru.
The core of this aloe appears to have survived. Hopefully this cactus will pull through.
These two dozen smaller clay pots of aloes appear to all be dead. The leaves are soft goo that froze and thawed. The totally soft ones, where the entire core is soft, are now in the compost pile. A whole summer of raising and growing the pups is gone.
This is the second winter that found my aloes frozen. Last winter I had a few dozen smaller pups in two to three inch pots freeze, but they were on shelves next to the plastic green house walls and their freezing was no surprise. These plants were on the ground and closer to the heat so I was unprepared to see such devastation. Next winter I may have to keep them in a sun-less storage room attached to the house. That will be a lot of work hauling all those pots from the green house hundreds of feet across the yard to the shed. That is, of course, if I have any surviving aloes that product more pups.
