Efficient slowrelease watering system: This 20gallon tree watering bag delivers water slowly and steadily to the roots for deep irrigation while minimizing water loss. It features two small holes on each side of the bottom to provide continuous moisture for up to 5–8 hours, helping prevent both overwatering and drought stress. Durable and weatherproof design: Made from UVresistant and tearresistant PE material, it is built to withstand outdoor conditions, including harsh weather and sun exposure. The sturdy construction reduces the need for frequent replacements, and the design prevents leakage to guarantee a consistent water supply through the seasons. Easy to use and install: No complicated tools or settings are required. Simply wrap the bag around the tree trunk, zip it up, and fill it with water using a standard garden hose. The largecapacity water inlet allows quick filling, and the selfdrainage system ensures a slow, steady release of water. Suitable for tree trunks up to 4 inches in diameter, or use multiple bags zipped together for larger trees. Watersaving and ecofriendly solution: By preventing water evaporation and runoff, this slowrelease bag minimizes water waste. Directly delivering water to the tree roots maximizes absorption efficiency, saving time and reducing the frequency of watering. Use scenarios: Newly planted or transplanted trees in dry climates, where deep, gradual watering supports establishment without runoff. Landscape installations with limited irrigation, improving water efficiency and tree health during hot periods. Large trees or clusters: combine multiple bags zipped together for trunks larger than 4 inches to ensure even distribution.
