We recommend ours: SeedLaunch Pro™ Germination Maximizer + Starter Fertilizer 8-15-10. It's a professional turf formula engineered to enhance germination, support early root development, and deliver controlled feeding to drive new lawn establishment and give every seed the best chance to succeed.
Big-box store starter fertilizers are all pretty similar and you can't really go “wrong” choosing one over another—provided you stick to the recommended application rates. 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 as 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.
