There’s a secret behind achieving a beautiful, lush lawn. Landscape professionals know what it is, but many homeowners don’t. Overseeding—as part of a comprehensive, proactive plan—keeps lawns looking great. Whether you’re tending your first lawn or have years of experience, learning how to overseed your lawn can improve your results.
Overseeding is spreading grass seed over an existing lawn. Done right, it’s a straightforward process that gets results. As grasses mature, thinning is normal—especially if you enjoy your lawn and use it often. Overseeding keeps your lawn competitive and steeped in youth and vigor, without starting over from scratch.
The basics of overseeding are the same everywhere, but goals and timing vary based on geography and the type of grass grown. For success with overseeding your lawn, follow this basic guide
Establish Your Goal
Typically homeowners overseed to correct thin or thinning lawns, but seeding pros overseed to prevent said thinning. For lawns in warmer regions, overseeding warm-season grasses with cool-season reinforcements adds green color during winter. When warm-season grasses go brown, overseeding with a premium, cool-season ryegrass, provides a green temporary lawn while your permanent, warm-season grasses are dormant.
Spread Your Seed
Apply seed at label-recommended overseeding rates, using the lawn spreader that suits the job. A landscaper trick is to apply half one direction, and the other half at a 90 degree angle to ensure perfect coverage. Use drop or broadcast spreaders for large lawns and handheld spreaders for smaller areas. For small spots, simply seed from your hand. Work when the air is calm, so seed distributes evenly.
Fertilize Overseeded Areas
Avoid weed & feed products; the pre-emergent herbicides inhibit seed germination. Starter fertilizer, such as Anderson’s Starter Fertilizer 18-24-12, delivers essential nutrients for new grass. Phosphorus supports vigorous root growth, while nitrogen fuels top growth and greening. Some states and counties restrict phosphorus lawn fertilizers due to environmental concerns regarding runoff, but exceptions may be made for new seedings. Check with your local county extension agent about nutrient application restrictions.
Keep Your Lawn Watered
Newly overseeded lawns need consistent moisture. Keep seed and soil moist with frequent, light waterings twice a day for the first four days; water more heavily every other day for the next five days; then water as needed to prevent wilting. This encourages deep, healthy roots.
Keep your newly revived lawn looking its best with a regular, comprehensive maintenance plan that includes diligent watering, best mowing practices and proactive overseeding. A simple weekday lawn maintenance schedule can keep your lawn lush and your weekends free.
