We bought two trellises and screwed them directly to the raised beds and then screwed them together for more support. I seriously doubt a storm will blow these babies over and considering the storm that went through today I think that was proven out. These are the trellises that I'm using to grow my cucumber vines up so they don't sprawl into the yard or strangle the tomatoes. There are two broccoli plants in the front of the picture that were from our broccoli last year reseeding itself. It was a nice surprise when I found it growing. This is also my lettuce bed which is just getting started.
