Which starter fertilizer should I use?

We recommend SeedLaunch Pro, our starter fertilizer designed to be applied the same day as your grass seed. It's a professional turf formula that supports germination and early root development for new lawns and overseeding projects.

If you're using a big-box store starter fertilizer because you have some on hand, consider waiting until after your new seed has germinated. These products usually contain high amounts of fast-release nitrogen, which can cause a surge of top growth in your existing lawn while you wait for your seed to germinate.
