This porous terracotta vessel waters plants naturally and efficiently, right at their roots. With the Oya, the water doesn’t run off or evaporate like it does when you water at the surface. Simply plant the Oya in the ground and fill with water every few days. Your plants get exactly what they need and you save water and time.

  • Material: Terracotta
  • Care: Remove from soil before the ground freezes. Rinse with water
  • Saves Time: Water only every few days
  • Saves Water: Surface water is inefficient. Watering slowly at the roots produces a water saving up to 50-70%
  • Higher Yield: Well watered plants produce more flowers and more food
  • Plant 24" apart, coverage area of up to 2 ft.
  • Small Oya is designed for patio or porch pots and planters–small growing spaces of up to 2 feet long and/or wide. This versatile size can be planted in any garden space with 6 inches of soil or more
  • Medium Oya is great for planter boxes, small raised beds, and larger containers. A 6’ x 3’ raised bed is perfect with 2 medium Oyas
  • Comes with silicone lid to keep evaporation in and critters out (mosquitos, lizards, and other insects)

Summer sun is unforgiving this time of year and the Oya is giving plants a fighting chance, as well as allowing for a few days away from home


Great product

The product was able to let me have water go into the plants methodically instead of the soil being dry or too wet

I bought two of these for a 3 foot by 6 foot raised bed where I planted my tomatoes this year. My tomatoes have been thriving all summer. Where my other plants that rely on my watering regularly look like they are wilting in the summer heat, my tomatoes have been lush, healthy, and never look wilted in the summer sun. I've also had the best yield this year. I will be purchasing more Oya's for my other raised beds next year!More > < Less

My azalea has developed a love affair with the Oya - she is wrapping her roots around his whole body and sucking up to him. Any way they areey are sharing the whiskey barrel by my front door.
They are happy.
I am happy.

About GrowOya

Dig This

It can be easy to forget to water plants and we often waste water when we do. GrowOya solves both issues, elegantly.

This terracotta watering system simplifies—and improves—the process of caring for your plants. Simply dig the Oya into the soil (with the spout exposed) and fill it up every few days. Boom . . . you’re done. The Oya and your plants work together to do the rest.

The Oya’s porous terracotta material releases water slowly near the roots, where it's needed. This method saves a LOT of water (up to 70%) because it reduces runoff and evaporation. Put one or more pots in places that the hose or sprinklers can’t reach. Or use them anywhere and everywhere for effective, efficient watering.

Founder Josh McWilliams wanted to water his rooftop garden sustainably. So when he discovered the “olla” (pronounced ‘oya’), an ancient way of gardening with terracotta pots, he saw a chance to change the way people care for their gardens today. Fellow Founders Kenny Torrance and Brant Cheetham joined and GrowOya was born.

With the time-honored wisdom of the Oya, you’ll save time, save water, and grow happier plants.
