Styrofoam cups to the rescue (frost blankets, too)
We've had a very mild winter so far with just a few brief dips below freezing. So much so that I'd been lulled into thinking we were out of the woods. But all that is about to change as an arctic front is headed our way. The lows forecast by the various weather services vary wildly between 24°F and 28°F. 24°F seems unlikely, but even 28°F isn't good news for our flowering aloes. I'm not worried about the plants themselves—the majority of them are perfectly hardy—but the emerging flowers could be damaged to the point where they stop developing.
