Phosphorus-free fertilizer — it’s the law, and the only green way to go!

Phosphorus is the primary nutrient that turns our waters green with algae. To protect our land of 10,000 lakes and stunning rivers of all sizes, Minnesota prohibits the application of phosphorus-containing fertilizer to lawns. Find out more about this law and how you can use phosphorus-free fertilizer for a healthier and truly greener lawn with this Minnesota Department of Agriculture fact sheet.
