Keyhole gardens are a brilliant way to grow vegetables with little water. They have really made a difference to the lives of people who have received one. Students from Lampeter university work with the community to construct them for people in Chinamhora village.
They are a great addition to any homestead due to their benefits. One key hole garden will last four years without having to re-dig it. Although compost can be added as required to help the plants blossom.
The circular shape and the deep trench enable them to hold a great deal of water. This mean that they are self-sustainable. Crops in a keyhole garden will last longer with little water than crops on flat land. After a lot of water initially, keyhole gardens only need to be watered once a week.
Please see the process of constructing a keyhole garden below.
