Many people apply lime to their lawns on a regular basis. However, this is usually not necessary. Don't apply lime to a lawn unless the soil is tested, and the soil pH is low--below 6.5. Very few lawn soil tests in the Twin Cities area come back showing a pH less than 6.5. Lime is a source of the essential elements calcium and magnesium. Its primary function is to correct soil acidity. When possible, test lawn soils prior to establishing grass.

HOW TO APPLY LIME

• If the area needs lime, spread it before working the soil.
• Then mix it into the soil to a depth of five to six inches.
• Mixing lime into the soil is more effective than spreading the lime over an established lawn.
