You don’t need a structure. Make tunnels or domes out of chicken wire or hardware cloth for each row or container. You can move them around the garden easily.

That's a good idea. I keep most of these in containers and up on tables/benches to reduce the number of bed overs I have to do, but I could make a tunnel of either chicken wire or that bird netting and put that on the tables.

Shade house is complete. Though with our cloudy and chilly weather it's not really required...yet. I am still hopeful it will warm up. :o)
