Making Clay Ollas for the Garden
The six photos you see below illustrate several stages of making clay Ollas for the garden. An olla is an unglazed, porous, clay pot that is set into the ground close to your garden plants. When filled with water, it becomes a small aquifer that the plants can drink from. The water seeps through the porous clay walls and the plants roots take what they need directly from the surface of the clay pot rather than relying upon water being appiled at the soil surface and leaching down through the soil profile resulting in evaporative losses at the surface, too much water too quick as the water sinks down into the soil profile, and eventually water sinking below the root zone.
