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
@DecaturNature If there is anything I can explain further just let me know, I'm more than happy to share
