They are doing great Camp. Try the black plastic on the area they are to go for a couple days, then go for it. If they don't make it you can just plant seeds directly in the soil. You growing season is so much longer than mine. Your doing great!
Thanks Lisa!

I checked the farmers almanac for my zip and I’m right on time! 10-day says that it’s still in the 40s overnight next week, so I guess I could try to wait til mid-March? It’s up in the 60s-70s during the day.
