Proper steps for lawn care
I live in zone 6, and have (somewhat) i think tall fescue grass. But here is my problem: Most of my grass seems to be overrun with weeds. Second problem: There also seems to be a lot of rock in the soil- very large rocks (2-3 ft wide and long) at periodic spots in my lawn, about 4-10 inches deep. With both of these problems, here is my question: What should be the proper steps to try and get rid of the weeds and grow grass (removing the rock is not really an option).
Should I spray weed killer first, then arate the lawn, put top soil/fertilizer down, then overseed?
Should I mow before or after seeding?
I really am new at this, and have been failing over the last year and a half, so any help and tips would be great, especially as to the order of which I should do things. I was looking at trying to seed by Labor Day this year, and am trying to get a plan in place to help be the most effective that I can be.
