So last year I had tried using row covers to save some of my kale, spinach, broccoli, and cauliflower from bugs. I cut conduit tubing and hammered it securely to the ground and slid pvc over it making hoops. I draped the meeting over and secured it with clips as well as bricks.
Well, the wind just wrecked it all, leading to decimated and futile attempts to secure my row covers.
It seems like bunnies and the bugs leave my tomatoes alone, so this year I’m going to clip garden fencing and cage the kale, spinach, and broccoli to encircle square foot sections and then drape netting over reach individual cage. This way the netting has less free material to be caught by the wind. The only thing I haven’t figured out is how to tie the netting to keep it snug around each cage. I could do the mesh drawstring bags as an alternative, but that would cost more than a fool of netting from what I’ve seen.
You could try landscape staples, like they use to secure landscape fabric. The downside is poking holes in the netting could shorten its lifespan.
