The green poking up is 5" corn below the mini greenhouse. I doing this next year!
I am just using regular black weed fabric as a barrier and to help warm the soil.
Peppers transplanted today. The 10-day forecast looks nice and warm, but I always start twice as much in case of a late frost.
Update 5/19: the leaves nearest the bottom have all burned off! The black with the sunny days proved too hot even for the chiles. Solution is to cover with hay, grass or leaf mulch immediately after transplanting.
In another bed, I have planted the squash.
