SAVE Water & Money with Deep Drip® Watering Stakes! Deep Drip® helps water, fertilize and aerate directly at the tree’s roots while conserving up to 50% of your landscape water usage. Deep Drip®, is made of durable, recyclable ABS plastic. It's easy to install and can be placed in the hole during a new tree planting, or can be pounded into the ground via a sledge hammer with existing trees. Our UV protected caps were specifically engineered to take the hit of a sledge hammer – we guarantee them 100% not to break. You can can use Deep Drip® with your garden hose, flood irrigation, or in conjunction with an automatic ¼” drip line system. An internal filter keeps the dirt and rocks from getting into the stake and clogging the unit. Deep Drip® is also removable and repositionable as the tree roots grow out and farther from the trunk. Using Deep Drip® can help you establish and maintain a beautiful, lush landscape! Deep Drip® works well with all varieties of trees, shrubs & flowers and can be used in residential, commercial and agricultural applications.
