How to Adjust a Shrub Head Sprinkler

Not all sprinkler heads are created the same. Some are for watering the lawn, others for soaking plant roots and then there are those made for watering shrubs. While it’s possible to set a shrub head sprinkler on a riser so the sprinkler head can reach the top of tall shrubs, most shrub heads are 6- to 12-inch pop-up style irrigation sprinklers. This means they pop up out of the ground when the water is on and retract when the irrigation system is turned off. You are less likely to trip over a pop-up sprinkler.

Screwdriver

Instructions

- 1
  Grasp the shrub head sprinkler in your hand. Turn the center cap to the right as far as it can go, then turn it all the way to the left. This aligns the sprinkler head to the beginning point of the sprinkler cycle.
- 2
  Insert a screwdriver into the arc adjustment screw on top of the sprinkler head. Turn the screw fractionally counterclockwise to decrease the arc of the sprinkler head. Alternatively, turn the screw clockwise in small increments to increase the arc.
- 3
  Adjust the radius, or the distance the water goes by turning the radius screw on top of the sprinkler head. Turn the screw counterclockwise to decrease the radius and clockwise to increase it.
