Water Wise Garden
• Refill just once or twice a week What is an Olla?
Olla (pronounced oh-yah) gardening is an ancient method of drip irrigation. Irrigation by ollas “results in almost 100% of applied irrigation water being absorbed by the plants.” – Curtis Smith Extension Horticulture Specialist NMSU
How To UseFill unglazed clay urns with water and bury them near plants. The water slowly seeps through the porous clay, directly irrigating roots that encircle the urns to absorb leaking moisture. The tops of the ollas extend above ground so the urns can be refilled as water is absorbed. Ollas virtually eliminate the runoff and evaporation common in modern irrigation systems, allowing the plant to absorb nearly 100 percent of water. In places with water conservation ordinances, ollas can help maintain a steady flow of water to plants because the urns only need refilling once or twice a week. |
