Africa can be a difficult place to grow food. Some areas in Africa have extremely poor soil conditions and times of minimal rain fall. Keyhole Gardening has been a successfully practiced African gardening technique which allows vegetables to thrive in areas of low rainfall. Organic garden waste naturally converts to nutrient rich garden soil. A central basket is used to put daily kitchen scraps offering constant nutrients to the garden.

We read about this technique a year or so ago and adopted the African Keyhole concept by creating a series of Keyhole Garden kits for the rest of the world. But because we were gifted the idea from the African people, we felt compelled to ‘give back’ for this ingenious idea.

Giving back gardens to Africa sounds like a great idea in theory – but where to start? So I contacted an organization my wife and I had dealt with for a few years. They operated directly in Kigali, Rwanda and offer a children’s sponsorship program. I told the organization of what we wanted to do, and we formed a partnership.

The Kageyo Garden Project was born, and we’re on a mission to build 500 Keyhole Gardens in Rwanda helping impoverished areas and bringing economy to the village. Since 2015 we’ve built 50 of them.
