A garden in a tall sack is a simple home project and a good solution for city homes that don’t have much outdoor space. We made one for the first time in a couple of hours, leaned it against the side of a house and planted it with hot peppers, basil and sweet potatoes.
Sack gardens can work in any city, but they can be especially important in developing countries and urban slums. Growing superfoods like kale, spinach and root crops not only cuts grocery bills, but infuses otherwise poor diets with vitamins and other nutrients. Woven plastic feed bags, food aid sacks burlap and other large bags have been converted into upright gardens in cities in Kenya and Uganda, schools in India, communities in Mozambique, South Africa and the Philippines. A good example comes from the UN Food and Agriculture Organization, which published notes from an interesting discussion of a garden program in Kibera, Kenya, by the French non-profit Solidarites International.
- 1 burlap coffee sack. Feed sacks and food aid sacks work, too, as would any large bag.
- 3 cubic feet of soil. We used organic compost, but a soil-manure mixture would work, as would compost from an ecological toilet, a household waste compost bin or any nutrient-rich soil.
- Gravel. *A large yogurt container with the bottom cut out. Coffee cans or other similar-sized containers also work.
- Starter plants. We planted serrano and habanero chiles, sweet potato, sweet pepper and two kinds of basil.
- Utility knife
- Trowel or shovel (optional)
We spent about one hour gathering the materials and 1.5 hours putting it together the first time. It could go much faster once you know what you’re doing.
Shovel the soil around the rock-filled container and fill out the sack to the edges. When the soil reaches the top of the container, pull it up gently, leaving the rocks in a column in the center. Repeat until the bag is full with a center column of gravel. The column is for drainage and water distribution throughout the sack.
Cut a small hole in the sack for planting along the sides.
Pro tip: We cut the holes too big. Try making a small cut that looks like an upside down “T,” then scoop out soil from below the cut to make a little shelf for the plant.
