Use of low-fired, clay ceramic vessels (ollas) an ancient technique for the efficient irrigation of crops. First in use in China and North Africa more than 4,000 years ago, the technique has spread throughout arid regions of the world. The use of ollas (pronounced oh-yahs) can save the gardener time, energy, and water. Olla users report that their vegetable gardens produce more lush plants with higher productivity. Plants watered in this way do not undergo stress cycles due to water and can live and produce longer. Ollas can be a relatively inexpensive way to maximize your garden output while minimizing overwatering, runoff, and water loss.
