Using a sprinkler system to deliver fertiliser directly to plants and grass is one of the easiest ways to ensure that important nutrients get applied evenly. Delivering a steady, uniform amount of fertiliser through the water supply can help grow stronger roots and lush, green lawns. Building your own in-line fertiliser system is relatively easy, and requires only a few tools. In-line fertiliser systems can be used on lawns of any size, and can be added to existing sprinkler lines.

Things you need
- Automatic fertiliser attachment
Locate the sprinkler manifold. This is usually outside and contained in a green and black box.
Open the sprinkler manifold box using your hand.
Twist the test caps on each valve within the sprinkler manifold to determine which zone you want the automatic fertiliser to be attached to.
Turn off the main water valve.
Use a wrench to remove the supply line from where it attaches to the valve where the in-line fertiliser is to be attached.
Connect the end of the supply line to the output side of the automatic fertiliser device.
Screw the intake side of the automatic fertiliser device onto the sprinkler valve.
Fill the automatic fertiliser with a quality fertiliser that's designed for use in your model.
Turn on the main water line.
Run the sprinklers and test for leaks.
Tips and warnings
- If there is not enough room in the sprinkler manifold to accommodate the automatic fertiliser, you may have to dig out the surrounding area and expand the manifold.
- Only use fertiliser approved for use in an automatic fertiliser.
