Seems like my #VerticalGardening is working... spinach, cabbages, lettuce and 2 tomatoes (just to experiment). The fertility is replenish by #composting kitchen scraps from an increasing amount of neighbors, which I plan to repay in food.
That's just a test, if it works properly I expect my yard walls to be covered by fall =D
@arteteco Impressive and intriguing. Can you share a description of what you did? It looks like used water bottles filled with potting soil -- and there must be holes cut in the side. Where do you compost the scraps, and how do you add them?
