Will Phosphorus-Free Fertilizer Keep My Lawn Healthy?

Phosphorus is necessary to grow healthy lawns. However, most soils in Ann Arbor, as well as many parts of Michigan, already have a sufficient amount. In these cases, adding more fertilizer is not needed and will not benefit your lawn. Healthy lawns can be maintained with phosphorus-free fertilizer. If you think that your lawn may not have enough phosphorus, you can have a soil sample tested for phosphorus content.  Soil Testing Information for Michigan
