The Vevor tree watering bag set provides slow, deep-root irrigation for newly planted and drought-sensitive trees. Each bag holds up to 20 gallons and releases water gradually over 5 to 9 hours to help reduce runoff and support healthy root growth. Made from heavy-duty weather-resistant PVC, the bags are designed for repeated outdoor use with reinforced zippers and sturdy handles. This 3-piece set fits trees with 1" to 4" trunk diameters and can be paired for larger trees. The wide fill opening allows quick, simple filling with a standard hose.
