Why Overseeding Matters
Overseeding is the process of spreading new grass seed over an existing lawn to fill in bare spots, thicken turf, and boost overall health. It’s a game-changer for lawns suffering from wear and tear, as it enhances density, improves resistance to pests and diseases, and elevates curb appeal. The best time to overseed depends on your grass type: late summer to early fall for cool-season grasses (like fescue or ryegrass) and late spring to early summer for warm-season grasses (like Bermudagrass). Key considerations include your climate (cool or warm), soil type (clay, sandy, or loamy), sun exposure (full sun or shade), and lawn usage (high-traffic or ornamental). Choosing the right overseeding grass seed ensures seamless blending with your existing lawn and long-term resilience.
