Use lime on a lawn if a soil test indicates that the soil is below the optimum pH level of 6.0 or 7.0. Soil that has a pH level below 7.0 is acidic, and soil that has a pH level below 6.0 diminishes plant health.
The best time to lime the lawn is before planting seeds on prepared soil. Lime can be applied any time to a lawn that is already growing.
Lime corrects soil acidity, adds calcium and magnesium to the soil and regulates other beneficial soil nutrients. Grasses in soils with the wrong pH level turn yellow and patchy. Calcium and magnesium protect grass from heat, drought and traffic stress.
To get rid of moss in a lawn, use moss killer on the lawn. After the moss dies, remove it from the lawn using a rake, and plant new grass in the empty spots. Water the newly planted areas frequently until the new grass is fully established.
Lime treatment is applied to a lawn using a rotary-style spreader or by hand if using ground limestone. Spinning and drop type spreaders also effectively spread the pellet form of limestone. Lime is applied in a pattern of intersecting lines across the lawn to ensure a complete treatment.
Lime is most effective when it is applied to a lawn being prepared for planting in the fall, winter or early spring, states West Virginia University. Lime may be applied at any time of the year on lawns that are already established.
To get rid of moss on your lawn, apply pesticide, improve the drainage of your lawn, and fertilize it regularly. If you can, it is also helpful to get more light to your lawn. It is best to treat moss with pesticide as soon as it appears.
Alleviating damp, shady conditions and physical removal of moss are natural ways to kill it. Moss grows in yards as a result of moisture, shade and poorly maintained lawns.
The benefits of liming a lawn include the restoration of the soil's pH for improved grass color and heat-tolerance. Adding lime to the lawn also helps the soil release nutrients to grass, for a pest- and disease-resistant turf.
The best way to tell if a lawn needs lime fertilizer is to do a soil test that measures the pH. Soil that is more acidic will benefit from lime fertilizer.
