My friends thought I was nuts, so did my husband until my garden went nuts and they were able to see for themselves that yes it is possible to grow tons of veggies in a small amount of soil. I stapled landscaping fabric inside the vertical pallet to form a “bag” if you will. And then just stapled more onto the inside of the one on the ground. I used a utility knife to cut x’s in the vertical bag after filling it with Miracle Grow potting mix and stuffed my plants into the x’s. Water, wait, water some more and let Mother Nature do her thing!
