considered the original drip irrigation system, Ollas are unglazed clay pots buried underground along side plants. The pots are filled with water, which then gradually seeps out through the porous walls into plants root zones.
These great garden beds have been build in a back yard in Los Angeles to house about 45 chilli peppers. A series of EasiOyYa's are connected back to the rain barrel so the owner can go away for weeks at a time confident to know that the plants have access to all the moisture they need 24/7. Since the water is delivered by these ollas straight into the root zone, there is no run off and minimal evaporation.
