What is Lawn Overseeding?

Overseeding is the process of spreading new grass seed over an existing lawn to improve thickness and fill in weak or bare areas.

This helps:

  • Increase lawn density
  • Improve color and appearance
  • Fill in patchy or thin areas
  • Strengthen resistance to weeds
  • Promote healthier, more uniform growth

It’s one of the most effective ways to improve a lawn without starting over.

When Your Lawn Needs Overseeding

Overseeding is recommended if your lawn has:

  • Thin or sparse grass
  • Bare or patchy spots
  • Faded or uneven color
  • Signs of wear from traffic or weather
  • Aging or declining turf

Most Seattle lawns benefit from overseeding once per year, especially in spring or fall.

Our Overseeding Process

We follow a proper process to ensure seed-to-soil contact and successful growth:

  • Mow lawn low to prepare surface
  • Dethatch if needed to remove buildup
  • Core aeration to open soil
  • Apply high-quality grass seed evenly
  • Light topdressing for protection and moisture retention

We don’t just spread seed—we set it up to grow.

For best results, overseeding is often combined with:

  • Aeration to improve soil contact
  • Compost or topdressing to boost germination
  • Fertilization for stronger growth
  • Lawn leveling for uneven areas

These additions significantly improve success rates and long-term results.

  • Thicker, fuller lawn coverage

  • Reduced weed growth over time
  • Stronger, healthier turf
  • More resilient lawn overall
