Know before you buy
On average, you will need to refill your Oya once every seven days. This duration can vary slightly depending on your local climate, soil type, and the specific water needs of the plants surrounding it.
The Oya comes in three sizes, each designed to cover a specific diameter ranging from two to four feet. Choose the size that best matches the root zone of your garden bed; for larger plots, you can also use multiple units to ensure even coverage.
The Oya is most effective in loose, well-draining soil that allows the terracotta to release moisture properly. If you have heavy clay soil, you may need to mix in some organic matter or sand around the vessel to help the water permeate the surrounding area.
Yes, terracotta is porous and can crack if water freezes inside the vessel during cold winter months. We recommend removing your Oya from the ground before the first frost and storing it in a dry, protected area until spring.
By delivering water directly to the root zone beneath the soil surface, the Oya keeps the top layer of soil drier. Since most weed seeds require surface moisture to germinate, this targeted approach significantly inhibits their growth.
