Ollas is the answer to use up to 90% less water in your garden.

It is an ancient irrigation technique, self-watering, low-tech, easy to DIY, that will keep your plants watered in the driest conditions.

Ollas are clay pots that are buried underground; the clay walls have a lot of holes in them and water can pass through slowly into the surrounding soil where it is absorbed by the roots of plants that are growing nearby.

This irrigation technique delivers water underground and directly where it is needed; when the soil is less saturated with water, the Clay’s water flow outward, when the soil is fully saturated the water stops flowing outward.

This mean the soil never gets too wet or too dry.

This work according to the Permaculture principle n.4 (from David Holmgren): Apply Self-Regulation and Accept Feedback.

You can combine the use of Ollas with several techniques recommended in Permaculture like raised beds, mulching and Compost Tea.

It’s enough you put your Compost Tea in the Ollas but remember to be careful about particles because you might clog up the pores and decrease the Ollas effectiveness. I recommend to filter very well the Compost Tea before adding that in the Ollas.

I am sure ollas are very efficient, however I wonder if they don’t prevent roots from growing deeply as they may stick too close to the ollas? Thanks for your explanation!

    Hi Sabine, it’s difficult to answer, the circumstances can change a lot the situation. What you’re saing is possible..

    Ollas, or unglazed clay pots buried in the soil, can be an efficient way to water plants as they allow water to seep into the soil gradually and directly to the roots. However, it is important to ensure that the ollas are placed at the appropriate depth and distance from the plant roots to prevent any potential root damage. We recommend consulting with a local permaculture expert or conducting research to determine the best placement for ollas in your specific garden. Additionally, keep an eye on the plants to make sure that the roots are healthy and growing properly.
