All except for the one behind the fence have trellis netting. It feels quite strong and hopefully we will have some watermelons with which to test the strength. The diagonally tied nylon lines and the nylon lines connected to the fence are to prevent the trellises from leaning too far forward or backward under lots of weight. I discovered that they would do that yesterday while stress testing the trellises. I'm an engineer, after all. Still need a couple more anchor lines on a couple more of the beds.
Hopefully this summer we'll have walls of produce growing on them.
