Reseeding Your Lawn with Roundup® Weed & Grass Killer Products

About 2 weeks before you plan to reseed your lawn, mix Roundup® Weed & Grass Killer Concentrate Plus in a tank sprayer and treat the entire area to be reseeded. Use 6 fl. oz. (12 Tbs.) per gallon of water for each 300 sq. ft. and apply evenly over the treatment area. If green patches remain after 7 days, reapply. After everything is completely dead, rake the area to remove the debris.

If your soil is really compact, now is a great time to core aerate. After aerating, rake the area level, loosen the top ¼ inch of soil, then spread a 1-inch layer of compost evenly across the entire planting area.

Choose a grass seed variety that’s right for your location. Do you need a cool-season grass that stays green during cooler temperatures in the North? Or would you be better off with a warm-season grass that stays green during the hot summer months in the South? You’ll also want to consider potential wear and tear from kids and pets, and how much sun your yard gets. If you need help finding the right grass seed for your growing conditions, check with your local garden center.

Once you’re soil is prepped and you’ve selected your grass seed, it’s time to seed. Fill up your spreader with grass seed, adjust the spreader settings according to the label directions, and apply.

After spreading the grass seed, apply a granular lawn fertilizer specially formulated for seeding. That way, those developing grass seedlings will get much-needed nutrients so their young root systems can grow deeper, faster.

Watering correctly (and frequently!) is non-negotiable if you want a successful seeding project. The soil surface should be kept moist by watering daily (or more frequently, if needed) until the seedlings reach a mowing height, usually 2.5-3 inches tall.
