The answer to 'how often to seeding' is that most lawns should be seeded every 3-5 years to maintain a healthy, lush appearance. Seeding helps to fill in bare spots, improve soil quality, and encourage the growth of new grass. The ideal time to seed a lawn is in the fall, when temperatures are cooler and there is more rainfall to help the new grass establish itself.
Factors like climate, grass type, and lawn usage can impact how often seeding is needed. For example, high-traffic areas or lawns in hot, dry climates may require more frequent seeding. It's generally recommended to consult with a local landscaping professional to determine the optimal seeding schedule for your specific lawn and needs.
