California's dry summers demand water-wise irrigation, and ollas offer an elegant 4,000-year-old solution. These unglazed clay pots buried in your garden slowly release water directly to plant roots, using 50 to 70 percent less water than surface irrigation. Perfect for Santa Cruz County's Mediterranean climate, ollas work in foggy Aptos, clay soil in Soquel, or sandy soil in Boulder Creek. Learn how to install, use, and even make your own DIY ollas.
