Do Less. Grow More 

A central compost basket is used in the Keyhole Garden to conveniently place your daily kitchen scraps. This household waste is then organically transformed into nutrient rich soil that nourishes your vegetables. Compost fed soil better holds moisture and nutrients, while using up to 70% less water.   


Wood Reimagined 

Cedar contains natural preservatives that help it resist insects and decay. Mezza cedar boards are treated with a warm, distinctive water-based stain that make it safe for the environment and ensure healthy, safe food production. It’s smart, sustainable and beautifully crafted. 


Simplicity and Ease 

Boards slide into posts easily and conveniently, with no need for tools or screws. Our innovative posts make for perfectly modular beds, allowing you to design and configure your own unique garden layout and size. 


Inspired to Give Back 

Vita designers stumbled upon the Keyhole garden concept while researching organic gardening methods. This inspired them to create their own series of garden beds using this African gardening technique. This idea was gifted to them by the African people and so they felt compelled to give back.  

The Kageyo Garden Project was born, and now partnered with “Thrive”, Vita distributes a portion of their Keyhole profits to build Keyhole Gardens in Rwanda and educate communities in sustainable, healthy food production.
