Trickle ring

A trickle ring is a circular drip irrigation device which evenly distributes water around the base of a tree or shrub. Connected to a water supply by a garden hose or tubing adapter fitting, trickle rings may be integrated into an irrigation network which waters many plants at the same time. By regulating the flow of water through the trickle ring, soil can be saturated at a rate which conserves water by minimizing wasteful surface runoff and losses due to evaporation.
