OK, so it's just a structure to protect the lettuce from being eaten by the birds. It's covered with the same plastic fencing that I use to enclose my garden. The top netting is only attached at the back, and hooks over the heads of three screws at the front of the cage.
The little seedlings have been moved, and nothing can eat them now. There is 12 square feet of planting space, and I set my lettuce plants in at two (or more) to a square foot, so the bed will hold a minimum of 24 plants at a time. That's more than enough for our use, now that we don't have a rabbit to feed.
I hung three S-hooks from the chain link, so the plastic netting can be raised and hooked to them for easy access to the bed.
It's pretty ugly now, but I think, as the new wood weathers to a soft gray like the cedar fence, it won't stick out like a sore thumb. I'll plant some other veggies by it......there's still enough room for some broccoli plants nearby. That should help hide it, too.
What we don't go through to keep our precious gardens safe from predators.
