Most lawns don’t need any extra phosphorus, plus, it’s the law.
Use phosphorus-free fertilizer on your lawn unless you’re growing new grass or a soil test shows your lawn does not have enough.
In 2012, the State of Michigan enacted a ban on the use of phosphorus containing fertilizer to curb water quality problems in our state, which helps protect inland lakes and stream and preserves the beauty of the Great Lakes.
Look for the zero in the middle on the bag.
More Tips:
- Fertilize in fall for best results
- If you must, be patient in the spring – wait until May
- Don’t fertilize frozen or saturated ground
- Confirm spreader settings and spray out spreader in the grass, avoiding hard surfaces
- Never spread near lakes, rivers, streams, and storm drains

When excess phosphorus gets washed into lakes and streams it can wreak havoc, causing algae blooms, and killing fish – lowering the amount running off your lawn helps keep our water clear.
