We have been in the high 60's to high 70's here for about two weeks now, and then this morning we woke up to cold grey weather and temps that never got out of the high 30's. I had alot of stuff poking up...some tall phlox, some astilbe, and a couple of very precocious hosta, that I am a bit worried about. I turned nursery pots upside down over the hosta because I consider these the most vulnerable. Do you think any of the other stuff needs to be protected until temps warm back up the first week of April?

Sorry for all the newbie questions...I've been out of the gardening game for awhile and have forgotten so much!!
