I assume you live in Nebraska and you likely have cool season grasses. What kind of grass do you have?

What was the fertilizer?

How have you been watering since reseeding? How often and for how long?

Generally don't put off lawn maintenance until spring if you can do it in the fall. Despite the Scott's commercials (usually beginning in February), spring is not a good time for seeding or even fertilizer. The "April Showers" time is good for preemergent herbicide, but other than that, try to resist the urge to fix things in the spring.

Thank you! I have KBG/Fescue and it was Lesco starter fertilizer that was spilled. For the first 7-10 days I watered 3 times a day for 3-5 minutes. Now I'm back to 1/2 and inch twice a week.

Ok I was just re-seeding and noticed a spot with grubs!!! Is it too late to put down the grub killer?

Pull up a green section and see if there are an equal number of grubs. It is normal to have some.

Yes dig up 1 square foot of grass and count the grubs. If you have fewer than a dozen you're okay. If you have hundreds then you need to do something. Generally this is the time when the grubs have stopped feeding, so it's too late to apply anything. You can kill them if you want to but it's a waste of time, money, and insecticide.

This time of year you should likely be watering 1 inch every other week...except for the area where you reseeded which needs a little bit of water, 3x per day to keep the seed moist.
