Should I fertilize before or after seeding grass?
When seeding grass, the order in which you add the fertilizer and seeds doesn’t matter, but adding fertilizer at the time you seed a lawn is important. You can combine the fertilizer and seed and broadcast them together, or you can broadcast the seed and fertilizer separately, one immediately following the other.
How do I start fertilizer on my lawn?
When you start your lawn, spread a starter fertilizer over the ground with your grass seed. You can broadcast the seed and fertilizer separately, one immediately following the next, and it does not matter which order you spread it in.
How do you fertilize a lawn after overseeding?
If you overseed your existing lawn, you can sow the seeds first (after raking any thatch buildup) and then apply the starter fertilizer across the lawn to lightly cover the seeds and deliver the proper nutrients. The new seeds will germinate and mix into the existing grass matrix.
How much fertilizer do you put on new grass seed?
But if you did not test your soil, experts recommend between 0.5 and 1 pound of nitrogen per 1000 square feet as anything beyond 1 pound can burn the young grass seedlings. A starter fertilizer with an N-P-K ratio of 10-6-4 or 15-10-10 is acceptable for promoting the early growth and development of grass seed.
