The experts all agree that regular overseeding is vital to help thicken your lawn and fill in bare spots, which reduces or eliminates competition from weeds. The reasoning is that young grass will produce new growth faster than older grass. After several years, mature plants begin to slow down their reproduction rate.
How effective is overseeding a lawn?
THE BENEFITS OF OVERSEEDING
Overseeding newer turfgrass varieties into an older lawn can help it better withstand insects, disease, drought, shady conditions and heavy traffic. The investment in overseeding pays off by reducing the amount of fertilizer, water and pesticides required.
When should I overseed my lawn?
Overseed in Spring
Oversowing in early Autumn means the seed has time to establish prior to the cold season and will prepare it for the cooler winter weather. Overseeding in Spring will rejuvenate your lawn after winter.
