The 15-gallon tube slowly releases water through a drip emitter; it is unique among tree-watering solutions as it saturates the soil during the first few days, and then slowly reduces water flow (as the water level decreases in the bag, so do pressure and drip rate). Reduced watering encourages the growth of feeder roots as the tree learns to adapt to drier periods.
Once empty, the polyethylene tube is refilled and the watering process is repeated. Fertilizers can be combined with the water. A worthwhile investment to ensure healthy growth of new trees.
