Ground limestone is used as a soil conditioner; it corrects acidity, supplies calcium and magnesium to plant roots, and increases bacterial activity in the soil. Limestone is not a fertilizer and should not be used in lieu of one. Specialists with West Virginia University Extension Service suggest that you lime your lawn every three to five years, based on the results of an annual soil test. Applying ground limestone is easy, and the ideal time to do it is in the fall.
Things You'll Need
- Drop spreader
- Dust mask
Test the soil pH. This will help you to determine the amount of lime to add. Your county cooperative extension service offers soil testing and recommendations based on the results, for a small fee.
Place the spreader on the driveway, sidewalk or other area where it will be easy to clean up any spillage.
Put on your dust mask and gloves.
Pour the suggested amount of ground limestone into the spreader.
Walk the edges of the lawn, spreading the ground lime.
Apply the ground limestone to the lawn in strips. Each strip should abut the previous strip but not overlap.
Water the area, to a depth of 1 inch, to dissolve the limestone into the soil.
