A Keyhole Garden for Households in Africa
“Another fantastic idea I picked up – which could make its way onto my allotment before long – is the keyhole veg bed. This is a raised bed with bells on: it’s about 1m (3’6″) high, and the outer bed, where the vegetables are growing, slopes down from a central hollow column. There’s an access path to the column (giving the bed a “keyhole” shape viewed from above) and inside it is what amounts to a compost bin, held in with hessian: you fill it with kitchen waste, stable manure, grass clippings – whatever you’d put on your compost heap.
Then tip on water saved from your washing up, and that’s it. “The idea is that the water will drain through and take all the nutrients with it,” explains Kirstine. “It’s feeding from below the topsoil, so rather than watering on the surface and all the water evaporating, everything’s coming up from underneath.” In Africa, this garden will feed a family of six through the three-month dry period, when crops in the fields simply dry out.”
Below, a video titled: Lesotho – Make a Keyhole Garden
“A great little video made in Lesotho, showing how a group of schoolchildren made a keyhole garden. The charity Send a Cow showed them how to make it and the children can now make their own at home and have more food.”
