What Is Lawn Overseeding?

Overseeding is the process of spreading new grass seed into an existing lawn to increase turf density and improve overall appearance.

Benefits include:

Frequently Asked Questions

What does overseeding accomplish?

Overseeding introduces new grass seed into an existing lawn, helping improve turf density, appearance, and long-term performance.

When is the best time to overseed?

Spring and early fall generally provide the best growing conditions because temperatures and soil moisture favor seed germination.

Should I aerate before overseeding?

Yes. Core aeration improves seed-to-soil contact and often increases germination success.

How long does grass seed take to germinate?

Most lawn grasses begin germinating within one to three weeks, depending on seed variety, temperature, moisture, and growing conditions.

Will overseeding repair bare spots?

Many bare or thin areas improve through overseeding, although severely damaged areas may require additional lawn renovation or sod installation.

Should I water after overseeding?

Yes. Consistent watering is essential during germination and early establishment.

Do I need to be home during service?

No. As long as our crew has access to the lawn, the work can generally be completed without anyone present.
