This is garden bed specific drip-soaker technology that delivers water directly to the roots, not into the air and everywhere else. These durable, flexible and easy to use driplines are made from UV resistant polyethylene. In-line emitters are evenly spaced @ 7 inches apart along each dripline and can be run on the surface or covered in mulch for even less evaporation. A course has been designed for each of our garden bed models and landscape pins are included so that the instructed course can be permanently affixed. You will use less water, achieve higher yields and make watering your garden beds a quick and easy process.
