What about late freeze damage?
I'm now paying for all those nice balmy February days. My hosta are coming up, but we're back to freezing/near freezing temps at night. I'm covering up the ones that have leaves already, but lots of them have tall pips. At what temperature are the leaves damaged? Are the pips different? I covered up those that are already leafed out with another pot, upside down. I couldn't think of anything that would really keep them from damage, so I used pots the last two nights. Then, this morning I thought of floating row cover, which I have plenty of. (The darling demon doglet would love the row cover, I'm sure - and she gets up before I do.) This weather is supposed to continue all week - cool sunshiny days and cold nights.
