Why and When to Overseed the Lawn

Overseeding is as simple as it sounds. You plant new grass seed in your lawn’s troubled spots. But its benefits go much deeper. You should consider overseeding because:

  1. It thickens turf, which discourages weed growth.
  2. It repairs burned or bare spots of grass brought on by summer’s heat.
  3. It improves the overall strength and vigor of the lawn.
  4. It’s the best way to create a uniform-looking lawn without having to do a full renovation.

When to Overseed Your Lawn

The trick to proper overseeding is knowing your grass type. The two main kinds of turf—warm season and cool season grasses—are on different seeding schedules. Below are the most common grass types in each region of the U.S.

Before You Overseed…

Aerate! By poking tiny holes in the soil, or aerating, you help more air, water and nutrients reach grass roots. Then, when you plant your new grass seed, they’ll have a better chance of sprouting and growing strong roots.
