I'm in zone 8 and planted tulips in November. I live in Medford Oregon and we've had an unseasonably warm winter. Bulbs have sprouted to about 3-4 inches. Now it seems that it is very possible that we may have some very colds nights. Should we cover the bulbs? Husband has been raking the moss out of our lawn. Could we cover the bulbs with Moss to try to keep them warm until hopefully, the beginning of Spring will bring warmer weather?
You can cover them a little, but they are real champions when it comes to the cold weather. They will do just fine, and may even survive a heavy frost at this point. There are many plants that will be coming out about this time of year. I believe they will be just fine.
