Ollas are an ancient watering saving method that works perfect for potted plants. A 1 quart Olla is the perfect addition to the center of a pot or container. Simply burry the Olla in the center of your pot leaving about 2 inches of neck exposed and plant your plants around the the Olla. We recommend after initial planting to wet the soil and then let your Olla watering system keep your plants watered and flourishing. Fill with water and replace the lid to prevent evaporation. Refill as needed.
