I now have several already-built beds to re-prpose.
I used one of them for a worm bin under the rabbit cages, and I still have all of these:
Two 3'x6' beds, and three or four 18"-squared beds.
I'm going to get some thick underlayment to prevent the Bermuda grass from growing up this time. I have a composter full of donkey manure from last year that will make a great soil base. And if there are weeds, I can solarize it, or just pull them.
