- 1). Divide the amount of limestone you need to spread over the grass and flowerbed areas. Your existing soil's pH determines how much lime you need. For example, gardeners with a soil pH of 5.6 to 6.0 should spread 50 lb. of limestone per 1,000 square feet.
- 2). Pour half of the amount of limestone you need for the yard into a drop spreader. A drop spreader reduces the amount of dust generated from the limestone.
- 3). Push the drop spreader horizontally over the lawn or flowerbed. Walk slowly to ensure that you do not miss any areas.
- 4). Add the rest of the limestone you need into the drop spreader. Push the drop spreader vertically over the yard to achieve an even spread. Go back over the lawn and smooth out any heavily distributed areas with a rake.
- 5). Water the yard with 1 inch of water to allow the limestone to absorb into the soil. Limestone left on top of grass or other plants increases the risk of plants burning.
