It has been unseasonably warm here in Michigan and my blueberries are starting to bud out. Now, it's going to be in the upper 20s here tonight, and I'm worried about losing the buds.

I planted them in August, 2010 and this is the first year they have any buds to speak of...I don't want to lose them!

Please help! I only have bedsheets that I could drape over them, if you think I need to do it. Here is a shot of how far they've progressed:

Thanks in advance,
