The answer to 'how does lawn fertilization work' is that lawn fertilization provides essential nutrients to your grass to promote healthy growth and a lush, green appearance. Fertilizers contain a balanced mix of nitrogen, phosphorus, and potassium, which are the three primary macronutrients that grass needs. When applied to the lawn, these nutrients are absorbed by the grass roots and used to fuel photosynthesis, root development, and overall plant health.
Proper lawn fertilization typically involves applying a granular or liquid fertilizer product to the lawn several times per year, usually in early spring, late spring, and fall. The frequency and timing of applications can vary based on your local climate, grass type, and other factors. It's important to follow the instructions on the fertilizer product and adjust the application rate as needed to avoid over-fertilizing, which can damage the grass.
