Why Olla Irrigation – A Low-tech Solution Can Boost Your Crop Yield And Quality

When it comes to gardening practices, there’s a technique that harks back to centuries-old wisdom and combines simplicity with eco-friendliness – the olla. Pronounced “oy-yah,” this method of irrigation uses unglazed clay pots buried in the soil to deliver water to the plant roots, and has been used by various civilizations throughout history, from the ancient Greeks to indigenous peoples in the American Southwest.

Nowadays, they’ve earned their place as a valuable tool in modern gardening, offering a unique approach to efficient watering and nurturing thriving, water-conserving gardens.

Benefits Of Ollas

1. Water Efficiency

Ollas are unrivaled in their water-saving capabilities. By burying these clay pots in your garden soil, you create a subterranean reservoir. Water slowly seeps from the olla’s porous walls directly to the root zones of your plants, minimizing evaporation and water wastage.

3. Self-Regulating

One of the remarkable qualities of ollas is their self-regulating nature. As soil moisture decreases, water is drawn from the olla to the surrounding roots. Conversely, when the soil is sufficiently moist, the olla stops releasing water. This system is a lifesaver for forgetful or time-strapped gardeners.

4. Reduced Weeding

Weeds need moisture and sunlight to germinate and grow, but olla irrigation deprives them of both. Ollas water directly to the root zones, leaving the soil surface drier. This deters weed growth, saving you time and energy in weed control.
