What is Lawn Lime?
Lawn lime, typically composed of calcium carbonate, is a soil amendment that helps to raise the pH levels of acidic soils. It is primarily used to enhance the health and growth of grass by neutralizing acidity, thus creating a more favorable environment for nutrient uptake. Applying lawn lime can lead to greener, healthier grass and improved overall lawn health.
In addition to raising pH, lawn lime can also improve soil structure and drainage. The calcium in lawn lime helps to flocculate soil particles, promoting better aeration and water movement through the soil. This, in turn, can lead to a thriving lawn and reduce the need for fertilizers, as nutrients become more available in properly amended soil.
What is Garden Lime?
Garden lime, often referred to as dolomitic lime, contains a mix of calcium carbonate and magnesium carbonate. It serves a similar purpose as lawn lime, but it is particularly useful for garden beds where different plants may have varying pH needs. Garden lime not only raises soil pH but also provides essential magnesium, which can benefit certain plants and promote overall health in a garden setting.
The application of garden lime can enhance nutrient absorption for vegetables and ornamental plants. Properly limed garden soil allows for a balanced nutrient profile, helping plants to thrive.
