Thanks for the row cover info! I may just go get a couple from the nursery so I do not have to wait, then order the rest online.
Thursday and Friday nights are still showing under 40F at night. My problem is that I have to do a lot of up potting because all the trees are leafed out and I know this should of been done sooner. However, if I up pot everything before it is time for them to go outside, I will not have enough room to bring them all back inside when they are in their new larger containers. So I am stuck.
Cannot wait to get that greenhouse this year!
