The Vevor tree watering ring set provides deep, slow-release hydration for newly planted or drought-sensitive trees. Each bag holds up to 16 gallons of water and dispenses it gradually to help water reach the root zone. Built from heavy-duty weather-resistant PVC, these reusable watering bags are designed for long-lasting outdoor use. The set includes 4 bags sized for compatible young saplings and mature trees. This irrigation solution helps reduce manual watering while conserving water and time.
