Most lawns sprout within seven to 30 days after reseeding, but the timing depends on the climate and seed type. Cool-season blends pop faster in mild spring or fall weather, while warm-season grasses need steady heat. Good soil prep, even seed distribution, and two to three light waterings a day speed germination. Extra aeration or debris removal beforehand can tack on a few more days.

Overseeding involves spreading fresh seed over an existing lawn to thicken it, whereas reseeding targets bare or damaged areas where much of the turf has died or been damaged. Understanding which issue you’re facing helps you pick the correct fix—and avoid paying for services you don’t need. Your lawn care pro can evaluate your property to determine the most effective option.

Hold off on foot traffic until the new grass has been mowed three or four times—by then, the roots are strong enough to handle weight. Stepping on seedlings too soon can crush them and slow growth, so cordon off the area or stick to stones and pathways if you need to cross the yard.

Reseeding timing depends on the type of grass and climate. Warm-season varieties perform best when reseeded in late spring or early summer, while cool-season blends prefer early spring or early fall. Select a seed suitable for your region and keep it moist—giving it two to three light waterings a day during the first week helps jump-start germination and create uniform coverage.

Hydroseeding costs range from $500 to $4,000. A pro sprays a pressurized mix of seed, fertilizer, water, and mulch that delivers quick, even coverage—perfect for big or uneven yards. Talk with a local lawn-care expert to pin down an exact price for your lawn’s size, seed type, and overall condition.
