Your Lawn is alive! Like every living thing, it needs food. Fertilizer replenishes the soil with essential nutrients that serve as food for your grass. Soil nutrients can be depleted over time, and a constant supply of nutrients is key to having a lush lawn. Pair fertilizer applications with lime, and get ready for a greener, healthier lawn. Lime helps to slowly adjust the naturally high pH levels of the Poconos to a level more suited for growing healthy grass.
