Get in the habit of checking your lawn for damage and weeds (they quickly invade thinned grass) once it\u2019s fully green each growing season. <\/p>
Pro Tip: <\/strong>Overseeding weakened lawns has multiple benefits, like improving turf thickness enough to keep weeds naturally under control. It also \u201cprovides the opportunity to introduce newer, more disease-resistant and better adapted turf cultivars to the existing lawn\u201d, explains Fech.<\/em><\/p>

If your lawn has thin or patchy spots, overseed it every year. <\/strong>This will thicken it up and keep weeds from moving in where the grass is weak. <\/p>
You\u2019ll probably need to overseed annually if you\u2019ve got ongoing issues that keep your grass struggling, like:<\/p>
- Compacted, hard-packed soil<\/a><\/li>
- Heavy foot traffic from kids, pets, or entertaining<\/li>
- Soil\u2019s too acidic<\/a> or too alkaline<\/a> <\/li>
- Pest problems \u2014 chinch bugs<\/a>, grubs<\/a>, armyworms<\/a>, you name it<\/li>
- Fungal diseases<\/a> that won\u2019t quit<\/li>
- Big shade trees<\/a> <\/li>
- Harsh weather that beats up your lawn year after year<\/li> <\/ul>
Annual overseeding is pretty much a given when you move into a house where the previous owners neglected the lawn. <\/p>
It\u2019s also just part of life with bunch-type grasses like tall fescue, fine fescues, and perennial ryegrass \u2014 these don\u2019t spread through runners to fill bare spots like creeping grasses do (Kentucky bluegrass (KBG), creeping red fescue, most warm-season species)<\/a>.<\/p>
Here\u2019s a special situation:<\/strong> If you\u2019re overseeding Bermuda<\/a> with ryegrass for winter color, that\u2019s a yearly thing too. The ryegrass can\u2019t handle the summer heat, so it dies off, and you\u2019re back to square one come fall. Overseed in late fall to early winter.<\/p>
