Tired of standing next to a newly planted tree with a hose and seeing most of the water running away from the tree into the grass? Then make your job easier and more effective — use a King Tree Watering Bag. The King Tree Watering Bag distributes approximately 20 gallons of water around the base of the tree over a 4-6 hour period. This allows the water to be absorbed into the ground rather than run off. This is very useful when planting a new tree or watering a young tree in the dry time of the year.
