I just made some beds. I used brackets in the corners with some hefty screws that I hope will last a while. They take a lot of filling. We emptied a couple of compost bins into one of them. We have some soil we can use, but may need to buy more.

Oh nice, when they are only a level or two tall they work well. But I think I built mine too tall with the design.
Hah yeah they do need a lot of dirt, I mix in native soil and then amend with potting soil.
