Even though I did use a good amount of garden soil from around our yard, my own garbage garden experiment (better known as my experimental hugelkultur compost Fukuoka inspired salsa garden) was pretty successful but I hadn't compiled my photographic data that in a concise way.
Essentially, I used a lasagna garden method by topping the start of a hugelkultur raised bed with 'pickled' kitchen scraps, discarded garden veggie scraps, some goat poo and worm filled soil as sheet mulch on this bed. We eventually mulched the bed but continued to add fresh kitchen scraps throughout the spring and early summer while only deeply watering only once a week, sometimes less.
When the tomato plants started to die back in late summer, I cut them back down at ground level and planted garlic, onions and more Swiss Chard. Slugs and other garden pests ravaged the last crop of Swiss Chard, garlic and most of the mini greenhouse pepper seeds we added to the beds but the 'Charleston cilantro' or Vietnamese cilantro (polygonum odoratum), thyme and some of the peppers we added as seedlings are still going strong. I'm going to add pennies (minted before 1982) to the bed in hopes that the copper will deter those cursed slimeballs. Thanks Pinterest pinners for that tip!
The weather has been so mild in the Charleston area that I'm kicking myself for removing the tomato plants so quickly. The sad looking tomatoes we trimmed back at the community garden are coming back to life again. Dang!
While these techniques are probably old news to sustenance farmers, I hope it offers a novel idea or two for new and frugal gardeners around the globe..
