Hi,
I have a long plant bed about 20'x 3' in my backyard. Not much grew there; underground roots damaged my plants, so I made a few raised beds - about 2'x2' square and 8/10 inch high; it works well, but looks ugly. What is an inexpensive way to put a 10" high border around these? I have at least 6 raised beds.
Any Ideas???
