I probably didn't plant my bulbs (Hyacinths, Crocuses, and Daffodils) deeply enough in October, and some are poking through. I've been covering them up with compost and soil. Is that the right thing to do? And, at this point, I'm not sure when to let them do what they want. It's hard to believe we won't get "real winter weather" some time soon. Advice?
