This is such a great idea. There are some things I can borrow......from your.... Our garden! 8 foot deer fence, cinder block raised bed, organic soil, flagstone and crushed glass pathway, and a hoop-house.
Get the kids to make some with me. Raised garden bed made out of mosaic cinder blocks. I think I may just do THIS for our garden this year! Turn them on their sides and plant the seedlings in the open holes...perfect containment, no room for weeds! ;)
