Where water delivery to an individual plant is needed. Emitters attach to 1/2″ or 1/4″ poly to deliver water to landscape or garden. These Flag emitters are flushable and easy to clean out by removing the flag end. Install pointed end into water supply. The end where the water comes out can either be placed onto the ground (not stuck into the ground), or installed next to the plant with the help of a Short Stake.
