How Many Ollas Do I Need?

Place ollas at least every 2-3 feet in your garden for maximum impact. Larger ollas with a 2 gallon capacity can be placed up to 3-4 feet apart. Check the water level frequently and refill the olla as needed. The frequency depends upon the soil type, surrounding plant density, and weather.

Do Ollas really work?

Olla irrigation is most efficient for crops with fibrous root systems like squash, melons, watermelons, tomatoes, and chilies, but it can work well for establishing young trees. Bear in mind that tree roots can, over time, damage and even crack an olla, so keep an eye on them if they are emptying too quickly.

How far apart are ollas?

The OLLA spacing will depend on plant selection, soil type, and temperature. As a general rule, plant 18 – 24 inches from the center of the Largest OLLA, and 10-12 inches from the center of the Medium Happy Face OLLA.
