Will it hurt the grass seed in any way?

What I do for best grass seed results is mix the grass seed with equal amounts of organic lawn fertilizer. Organic won’t burn the new growth as chemicals might. Then I get some potting soil and cover the seed/fert. mixture with a very light dusting of the soil to keep the seeds in place and the birds from eating it.

Water every morning and evening till it germinates. Then just keep it damp for a few weeks till it starts growing well. Then just normal lawn care.
