The Vevor tree watering bags provide deep, slow-release irrigation to help newly planted and drought-sensitive trees stay hydrated. Each bag holds 20 gallons and releases water over 3-4 hours for steady root-zone watering. Made from heavy-duty PE woven fabric, these bags are designed for durability, reuse, and easy installation around tree trunks. They fit trees with 2-8" trunk diameters and can be zipped together for larger trunks. Ideal for home gardens, orchards, landscaping, and public green spaces.
