Lawn fertilization is a key component to having your grass grow strong and healthy. More than just lawn maintenance, fertilization treatments can improve your lawn. While there are many different types of fertilizers, the main nutrients in each are nitrogen, phosphorus and potassium. Your grass needs each of these nutrients to develop properly, and having the right amounts available will promote strong, thick grass cover for your lawn. In addition to looking great, a strong and thick grass cover also prevents weeds from growing in your yard. Multiple treatments or applications of fertilizer throughout the year is common, ensuring your lawn has the proper nutrients available all year long. Many landscapers and homeowners opt to apply organic fertilizer, which can promote grass growth while also being safe and healthy for the environment. While fertilizers are available at local hardware stores, most homeowners choose to have a professional landscaping company treat their lawns. Applying fertilizer improperly can have adverse effects on a lawn, so research, education and experience are important when thinking about a fertilization treatment plan. Done correctly though, fertilizing a lawn can improve grass health and overall yard appearance!
