Geraniums still alive! How to cold-frame them.
I can't believe it, but at least 3 of the geraniums (regular old zonals) I planted this summer appear to still be alive, even making new small leaves. Maybe because we haven't yet had a prolonged hard freeze. Is there a way I can cover them, like with a translucent plastic bowl, to keep them alive during the winter? Thanks. Happy Holidays!
