"Bulbs in the Basement" provides information specifically on many tender plants. Although Alocasia isn't one of them, the directions in the general information section would have told me to store the tubers rather than try to keep them growing in potting soil. It also lists the various pests and diseases that afflict indoor plants and advises how to deal with them.
At least I received the book in time to save the Ipomoea cuttings from death by overwatering. (I was trying to compensate for my underwatering tendencies, and they were starting to droop.) The book also validated my instinct to put the Pelargonium next to the patio door to keep it cool. With a forecasted low of -9F for later in the week, I'm thinking maybe I should move the Pelargonium until this Arctic blast has moved on.
I hope all of you are doing better than I am. Stay warm, stay sunny, and may you have abundant blooms.
