Re: new garden help!!
I converted my 20x70 into 10 raised beds. I used 4x8x16 concrete blocks. I used the original soil, peat moss, old pool sand, and leaf compost in each bed. I left about 20" paths around the beds which I filled with mulch. I get all the leaf compost and mulch at the township facility for free. The blocks are standing on end, so you can use the holes for pvc hoops, or fencing stake holes. Blocks were cheaper then using pressure treated.
