If things have flowers cover them. Peas should be fine unless they're starting to get pods. Seeds should be fine. I've had to cover my peach tree and my blueberry bushes as they already have blossoms but I'm not worried about anything else. I'll have to cover ours the next three nights (not tonight). I'm a day behind you guys, and Bee quite often seems to be a day behind me on weather.
They are seedlings. My peach trees had flowers. I picked them all off because they were just planted and I want them to focus on root growth. So I guess I'm good???
You should be good.
Also, it'd be good to have an outdoor thermometer and check it to your phone periodically. I've found if the forecast is 41° or below, we usually have frost at the house. It depends on where they take the measurements. Ours is in town, and seems to be quite different than our property.
Well not much going on around the place. We got the rabbit area completely sheet mulched. Still need to fence it. I plan on picking up at least a couple more fruit trees tomorrow to plant this weekend.
Hopefully we will find time to get a few more roosters in the freezer too!
