Haha - yes they are nice. I built them two years ago, before that I was tilling the space every year, and then it was almost an act of war to keep the weeds and grass out. For a few years just before building the raised beds we would tarp the ground with landscaping tarp and then plant through the tarps. That worked "OK" but grass and weeds still managed to work their way in. I finally decided to build the raised beds one year and it took me 2 days to build the frames which cost me less than $100 in supplies, and then we had to order garden soil to fill them. Filling with garden soil was A LOT of work, but it was totally worth it.
Here it is before we had raised beds.
Oh most definitely worth the money and time involved. I have one raised container bed full of garlic right now but would like to add two more; one for potatoes and one for onions. Those are staples in this house.
