Worried your plants will shrivel in the summer sun this holiday weekend? Instead of hiring a plant sitter, consider the clay option. That’s what the ancient Romans did when they used ollas, or unglazed clay vessels, as irrigation. The Romans filled the unglazed clay with water (today, you could hook it up to rubber tubing and the water supply) and buried it beneath the soil to gradually water plants at the roots. The benefits? Less evaporation, runoff, and surface-level weed growth, and overall maintenance. Here are our favorite terracotta ollas and “plant nannies” for keeping small crops, raised beds, and potted plants hydrated.
