Making a new raised bed at present: The first one I made about 15 years ago finally expired because I didn't use tanalised timber boards. I just screwed untreated 6"x2"x4' boards together with some 'L' brackets.
I'm making the new one using some steel channels welded together at 90° to each other to create 4 posts which I will concrete into the ground, then I can cut and slot in new boards. I'll post a pic later when it's all done.
