We tested three common mulches—wood chips, pine needles, and grass clippings—to evaluate their water-retention capacity. Using equipment often recommended by Lab Equipment Dealers & Suppliers Near me, we logged daily moisture levels to monitor performance. Wood chips consistently maintained higher moisture, making them ideal for water-conscious gardeners. Pine needles showed moderate retention, while grass clippings decomposed too fast. The test showed how the right mulch saves water and effort, especially in hot climates.
