Fertilizers containing phosphorus cannot be used on lawns in Twin Cities metro area counties (Anoka, Carver, Dakota, Hennepin, Ramsey, Scott, & Washington) unless a soil test indicates that it is needed or if establishing a new lawn.
Identify the Fertilizer
There are three identifying numbers on a bag of fertilizer. Find the phosphorus content by looking for the middle number. In Hopkins and other metro areas, the middle number must be 0.
