The numerous advantages of s​ack gardening and growing drought-tolerant Navajo willows (see below) have been described earlier in postings on my desertification blog. We suggested to combine both methods/techniques (sacks and live trees) in order to solve a number of classical problems: drought, limited quantity of irrigation water, heat, UV-radiation, etc, killing a number of birds with one stone. Mona HATOUM’s splendid artwork and the positive news about gardening people in Nairobi, combating hunger, malnutrition and poverty with “s​ack gardening”​, brought me to the idea that it must be possible to build a vertical vegetable garden as a F​ood Wall of stacked burlap (jute) sacks, filled with a mixture of dirt (or potting soil) and manure. Maybe adding a water absorbent soil conditioner (if cost is not a limiting factor!) can enhance the water retention capacity in the sacks.
