The Oya is an unglazed ceramic irrigation vessel that gets buried up to its neck in garden beds, raised beds, or near any plant that needs continuous moisture. The vessel is filled with water every five to ten days, and the water gradually seeps through the porous clay into the garden soil. Plant roots will gravitate towards the Oya, taking the water as they need it. This ancient method of irrigation conserves water by reducing evaporation and runoff.
