Mowing lawn after re-seeding - Knowledgebase Question

Redmond, Wa
Question by sunnyv6

AFter the winters, I raked out all moss and dry patches in my lawn to prepare the lawn for spring. Although only 20% of the lawn was affected with moss or dry pacthes, I added high quality grass seeds to the entire lawn and added Scott's fertilizer.

I thought I will wait for atleast a month to see the seeds growing. There had been a lot of rainfall recently in Seattle area which makes me wonder if the seeds would have got washed away and will not grow properly. Is that a possibility? If yes, should I add more seeds now?

Also, I also see that my lawn needs a mowing sometime soon but the seeds have not really germiinated. Should I mow or wait until I see the seeds germinating?

I'm inclined to think the rain has washed the seeds down to the soil level, which is a good thing. If they have good contact with the soil, they will root well when the weather warms up enough for them to germinate. Mowing shouldn't have much effect on the seeds, if in fact they have washed down to the soil rather than remained up near the tops of the grass plants. It's a little early to broadcast grass seeds; the middle of April is about as early as you'll want to do so. Grass will sprout and grow when temperatures are about 40F and they generally germinate within about a week. So, go ahead and mow. If you don't see any new grass by mid-April, you'll want to reseed in mid to late April.

Best wishes with your lawn!
