Balled-and-burlapped trees can be planted throughout the growing season, and the job is typically completed within a couple hours. Once the tree is in the ground, though, the work has only just begun. Young saplings need a steady supply of water to help their roots become firmly established. To fend off the ravages of summer heat and drought, you could stand out in the yard with a hose a few times a week, or you could make it easy with an Automatic Ooze Tube Watering System. This watering gizmo is designed to release a stream of water to the roots of the tree, keeping it moist but not too wet. All you need to do is remember to refill the tube, about every 2 weeks.. Available at Plow & Hearth; $14.95.
