The weeds are taller than the garlic inside the tire garden. The blackberries are okay so far but I have figured out a plan for weed control.
Yesterday and today I brought home cardboard from the trash bins of the hospital. Today mulch was delivered. The pile is in the back on the right. I'm going to spread a layer of paper and cardboard over the weeds and then put a nice layer of mulch over that.
I also intend to do it around the outside of the tires, too.
