The United States Department of Agriculture has actually produced soil maps showing the general soil types found throughout the United States. Not sure if you should add lime to your garden?

The only way to know for sure whether or not your garden needs lime is to have a professional soil test completed. Dig your soil sample from the area where you want to plant your vegetable garden, flowers or lawn.

If you get your soil tested at the end of the winter, add lime immediately as recommended by the test results. Mix it into the soil well before your frost-free date indicates you can plant your vegetables or flowers.

Gardens found in acidic soil areas benefit from annual or bi-annual applications of garden lime. Raised bed gardens may get away with fewer applications. A soil test, however, is the best way to tell whether or not it is time to apply garden lime.

Most home gardeners use a lime or drop spreader to spread powdered lime on lawns and gardens. A lime spreader is a machine you walk behind and push. It has a hopper in the front that you fill with powdered lime. A spreader then sprays out the powder in even amounts as you push the machine forward. To apply lime to lawns, fill the lime spreader with the appropriate amount of lime.

Lime for garden soil can also be scattered using a spreader. Mix it into the soil at a depth of about four to six inches. Lime needs water to mix into the soil and become available to plants. Think of lime like vitamins for the soil. Adding lime to the soil is like a vitamin. Lime can be very beneficial for lawns. Lawns that have yellow patches, brown patches, weedy areas or an abundance of moss may benefit from an even application of lime.

Weeds or mossy patches can both be signs that the pH of specific areas on the lawn differ from the overall pH of the lawn. Moss, for example, grows in acidic conditions — which can be improved by the addition of lime.

The stone is then screened into various sizes ranging from several inches to dust-sized particles. The sized stone is then washed. Preheating — limestone is heated by direct contact with kiln exhaust gases that enter the preheater kiln.
