African Keyhole Garden

The African keyhole garden is different from the Mandala design since the center of the raised bed is dedicated to nutrients and the access to the plants is done from the outside.

This example of a structure is made with bricks having no stones in Bahia Atlantic border.
Note the disposition of the bricks to increase the wall cohesion.
The V shape inclusion is the access path to the future basket of nutrients.

Put_cardboard_on_the_periphery_to_avoid_weed_invasion

Add_mulch_to_protect_from_the_sun

The next step is the construction of the raised bed. You may find many recipes on internet about the different layers; every one has his own method; …compost, mulch, brown and green manure, ashes, biochar, etc… The last layer is made of mulch, for example the leaves of a leguminous tree to provide with nitrogen and protect from the sun.

Add_manure_in_the_basket

Compost, mulch or manure is added in the basket. The basket is regularly fed by organic matter (mulch, kitchen scraps, animal manure, …). The idea is that watering the basket will bring the organic nutrients to the raised bed over time. The basket design acts as a nutrient chamber easy to fill where composting is accelerated and humidity better kept as well.
