low-cost easy raised garden beds?

17. If there aren't holes in the bottom, maybe could add a couple. Maybe give them an out.

Or could dump a handful of red wigglers in the top after planting, and pick a spot where you could feed them some scraps and brown stuff once in a while. Those would leave castings throughout and return for food to that spot. Those don't live that deep, and might be happy in the larger of these, if there is food for them. I have seen a piece of 4-6" PVC stuck in a bed, with some bedding and food dropped in, then worms. Then they just toss some food scraps down there on occasion, and keep a rain cover on it. The worms seem to gather around it.

One of the reasons I want to try it the beds (I think the retail on that is $40) is that I have major problems with crabgrass getting into my raised beds. I am having to rebuild them to remove it. It may be that this won't let it grow in from the sides. I am going to try one.
