The Best Grass Seed of 2024 for Overseeding in Spring
Hello, my friend, hello again; today we come together to talk about The Best Grass Seed of 2024 for Overseeding in Spring and hope the blog can help you.
Overseeding creates a dense, lush stand of grass—and an overall healthier lawn.
The best grass seed for overseeding a lawn will depend on the existing type of grass, the prevailing climate, and the soil type. After a few years, even the best-kept lawns can start to look sparse and worn out due to drought, under-watering, overwatering, or even growing a grass variety that’s unsuited to the region.
Overseeding a lawn with a superior variety of grass seed at least once every 3 years will keep the yard looking its best while helping it resist drought and disease. Because grass variety is regional and climate-based, we recommend Scotts Turf Builder Grass Seed Sun & Shade Mix for cooler regions and Pennington Smart Seed Sun and Shade Tall Fescue for warmer climates. Both seed mixes feature excellent disease and drought resistance and will work for most areas in their respective regions.
All grass seeds we recommend for overseeding are specific to the region they will grow best and feature good disease and drought resistance. Using the right grass seed for your lawn means you’ll be enjoying a beautiful lawn all season.

Before You Buy Grass Seed
Grass seed producers often coat seeds with a fungicide to enhance germination by preventing harmful fungi from damaging them before they sprout. While this treatment helps ensure more seeds thrive, environmental concerns may arise about using fungicides. To mitigate these concerns, it is essential to store the seeds in a cool, dry place and strictly adhere to the manufacturer’s directions for use. This approach minimizes any unnecessary environmental impact and maximizes the health benefits of growing natural grass.
How We Chose the Best Grass Seed for Overseeding
Extensive product research went into selecting this roundup of the best grass seed for overseeding. While grass seeds are limited to just a few well-known producers, today’s hybridized seeds and revolutionary seed formulas can produce lush, resilient lawns.
We tapped the experts at Sod Solutions to help us with tips for choosing the best grass seeds for overseeding. Valerie Smith, content strategist, has spent years with grass experts at Sod Solutions and shared her insights. She says when it comes to grass seed, it’s best to “choose a grass seed that aligns with your local climate and region—for cool season grasses like fescue or Kentucky bluegrass in northern areas and warm season grasses like Bermuda grass or centipede grass in southern regions.” The best grass seed will thrive in the specific region where it’s planted. “For best results, match the new seed to your lawn’s existing grass type when overseeding to maintain a uniform appearance in your lawn,” she advises.
We selected products based on brand reputation, the quality of the seeds—including the percentage of weed seeds in the mix—and how well each performed in its stated category or region. We opted for seeds that will strengthen and enhance existing lawns.
