The hyacinths and narcissus that I had in pots from last year are sprouting. Their leaves are already poking out of the soil, and the night temperatures are starting to hit zero and below. I covered the sprouting leaves with more soil, but I'm afraid they'll freeze before spring. I usually place my potted bulbs in insulated boxes. Should I do the same for these, or should I bring them inside to let them bloom? Any help would be appreciated. Thanks!
