Buried alongside plants, the Olla (or Oya) is a clay pot that acts as an underground water reservoir. Porous, the terracotta distributes water according to the plant's needs, without excess or evaporation. Gentle, self-sufficient and very economical, this age-old irrigation technique is suitable for all plant types, whether in the ground or in pots. Handcrafted in France by Poterie Jamet, using a blend of raw clay from French quarries.

Each size of olla watering pot has a specific range and autonomy time, see "product details" below. For more details, see our Journal article on how olla watering systems work and how to use them in the garden.

Data sheet


Dig a hole slightly larger than the volume of the olla. Water the hole and the soil around it to encourage water conductivity. Place the olla in the hole and bury it up to its neck. Fill with water and place the top over the opening. Mulch the surface to limit evaporation and improve the olla's irrigation capacity. Monitor the speed at which the olla flows and make sure it doesn't run dry. To apply fertiliser, pour it directly into the olla, diluting it with water. Even though frost-resistant, it's best not to fill the olla when it's very cold (except for plants stored indoors for the winter).

Olla, a watering solution that naturally adapts to your plants’ needs: terracotta plant waterers

Ollas: an Age-Old terracotta plant waterer to irrigate

 Ollas are the optimum eco-friendly solution to water your plants. This crop irrigation technique has been used in the driest regions on the planet since the dawn of time. Ollas are terracotta plant waterers that one buries near the plants’ roots before filling them with water. Through the porous surface of the container, the water flows out naturally based on the climate and the plants’ requirements. They offer plants a constant supply of water and spaces out watering. Depending on the size, they can last from one to four weeks between refills.  

In the ground or in BACSAC® planters

Terracotta plant waterers – or Ollas – have long been touted for the incredible benefits they offer plants and the environment. Ollas are well suited to container gardening and provide a sustainable solution for those who don’t have access to a sprinkler system.   Hand-crafted out of entirely natural materials, our terracotta plant waterers can be used in any climate and for any type of plants. Their mechanics are quite simple. When the air and the ground are dry, the Olla releases water. When the air and the ground are moist, the Olla retains water. The self-regulating properties Ollas possess are very beneficial to plants.   Ollas promote rational watering and can reduce the amount of water used by 50% to 75%. Much more sustainable than hand watering or sprinkler systems, Ollas protect plants from undergoing hydric stress or from receiving too much or too little water.   The hats on our terracotta plant waterers prevent evaporation when the weather is hot and regulate water temperature in winter. When the weather is very cold, preserve your Ollas by covering them up using mulch (straw, dead leaves gathered in autumn, etc.).

Terracotta plant waterers made in France

Manufactured by Jamet pottery, founded in 1974, our Ollas are the result of a two-year research process. These garden accessories were developed to be as effective as possible.
