I used weed killer almost 2 weeks ago and I think I am ready to seed and fertilize. My yard is around 9.000 sq ft and backyard gets lots of sun light but my trees block the half part so half part is shade and have almost no grass.(2000sq. ft.) My plan is seed then use milorganite. For shade part I think dense shade would be good the rest I can use shade & sun mix. Before seeding I will add some top soil. Any suggestions would be great. I haven't done any lawn care in my life.
Besides milorganite do I have to use anything else? Like turf starter etc?
Is it too late to seed now? I live in Kansas, it is end of may and weather the 70s.
Edit: I added some photos.
