It is going to get cold here, cold for here anyway. 4 days of freezing with 2 days the highs around freezing. I have daffodils and tulips in a 30x30 planter and some of them are 12 inches tall already. Last year I lost them all to a late frost in early April and I don't want it to happen again. I also have other tulips and Hyacinth coming up. I hope to be able to move them into the garage along with 3 other flowers and an onion. I buried everything in peat moss last year and all the starts died leaving no early blossoms. What can I do to try and protect the large plants, 3 of which already have flowers stems coming up? All I have is putting a tarp over them to try and keep them from freezing or getting frost damage. Is this even worth a try?
