A couple days ago we transplanted a dozen or so red oak lettuce volunteers, a mesclun mix, some mustard greens and half a dozen broccoli plants. And also cast seeds for several more rows of oak leaf lettuce. The bugs seem to leave the oak leaf alone and with the bird netting we should get a pretty good survival.
The bird netting box was made using pvc pipe and laying the netting over and tying off with short clips of fencing wire. I used this last year and it worked great and then was packed up nicely. It should only be needed for a month or so to deter the birds.
