Lime is a soil amendment made by grinding limestone, a naturally occurring type of rock that is very high in calcium. Two types of lime are commonly used in lawns and gardens, agricultural lime and dolomitic lime. Agricultural lime, also sold as garden lime, is made from calcium carbonate.
Lime can restore a patchy, weedy, or yellow lawn and return it to good health. To find out if your lawn could benefit from lime, conduct a soil pH test. WHEN. Wondering when to use lime on your lawn? The optimum time for liming is during the fall, because the cold and rainy weather can help push the lime into the soil. Plus, homeowners often aerate their lawns in the fall. If possible, apply lime to your lawn just after you aerate it. The aerated soil will help the lime sink deeply into the ground. Another great time to apply lime is when youâre preparing soil for seeding. If you need to know when to use lime on your lawn, know that this is one of the best times to act. HOW. Purchase your lime.
