The UC Guide to Healthy Lawns

Overseeding your lawn

When should you overseed?

  • Your lawn appears to be in good condition, but just a little thin
  • You are growing a warm-season grass that turns brown during the winter; overseeding with a cool-season grass in the fall ensures that you will have a green lawn during the winter months

Always determine and solve the cause of your current problem before beginning repairs, and plan to seed at a time of year appropriate to the planted turf species.

What should you overseed with?

If your lawn is in relatively good condition in most areas, choose the seed mix you used in the past or review the following tables for species that might provide better growth in shady or sunny areas or areas of high traffic:

If you are overseeding with a cool-season grass in the fall, your best choices are:

Annual ryegrass Red fescue
Kentucky bluegrass Rough bluegrass
Perennial ryegrass Tall fescue
