Premature sprouting in stored bulbs
I have a bunch of calla lillies and gladiolus bulbs that I pulled in the fall to store. They were nice and dry, but we've had some warm days recently. They're in my basement, in boxes lined with sand, but now it seems that they're sprouting.
What should I do to salvage them? I've still got about a month or two before I can safely plant them in the ground.
