Lawn fertilizer is a type of fertilizer that is used to help promote healthy growth and development of grass and other plants in lawns. The most common type of lawn fertilizer is LIME, which is a naturally occurring mineral composed of calcium carbonate. LIME helps to balance the pH levels of soil, making it more hospitable for grass and other plants. It also helps to provide essential nutrients to the soil, such as nitrogen, phosphorus, and potassium. Lawn fertilizer with LIME can be applied to lawns in either granular or liquid form.
