Can you put grass seed on top of an existing lawn?

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.

Can you use too much grass seed when overseeding?

New lawns or spot repairs take about twice the amount of seed needed for overseeding thin areas. Too much grass seed causes undue competition for resources such as light, water and nutrients, and grass seedlings struggle as a result. Too little seed leaves lawns thin or bare.

Can you fertilize and overseed at the same time?

Do I overseed or fertilize first?

Stop fertilizing for at least a month before overseeding. The fertilizer makes your grass grow faster, which makes it harder for the new seeds to take hold. Identify your grass type or the type of grass you want to grow, so you can manage it appropriately.
