Correct watering made easy: These beautifully shaped watering cones are buried in the soil in the plant pot with the unglazed lower section and filled with water via the upper opening. The microporous clay is fired in such a way that the pores remain open, allowing water to pass through. Clay absorbs and stores water naturally and releases it to the soil and plant in the optimum quantity - exactly as required. This good supply promotes root development and healthy plant growth. Overwatering and drying out are avoided. OLLAS should be refilled with water every 4 to 6 days, depending on consumption. Made in Portugal.
