I grow my vegetables in self watering growing containers I made myself, similar to the EarthBox system. Some of these vegetables such as tomatoes, capsicum, and sweet peas need to be supported otherwise they turn into a messy tangle, which I don't have space for. Here's one container, with a black wrap around it to help prevent algae growth. They only have 6 inches of loose soil, stakes won't stay up in there.



In some places in the greenhouse I can use the 4x2s of the greenhouse walls to hold up supports - I plan to use a mesh which is meant to be fencing, a meter wide with inch or so holes that I can tie the vegetables to. I need a way for this mesh to be supported either on the side of the bins, or for some of them like sugar snap pees across the centre.

As you can see with this bin my first idea was to tape bamboo stakes to the side, but in practice the tape isn't strong enough, the bamboo will move around and I think it'll come down eventually. Can anyone think of a good way to either attach the bamboo to the side of the containers, or for some self supporting system? I wouldn't like to pierce the containers, as they're full of water and soil, it would compromise their function. I could build a wooden frame, but that would block light. Cheap is good too.
