I'll start this by saying that I'm a new homeowner, and other than reading about a 1000 posts on this website in that past week, I have no previous lawn care experience other than mowing my parent's "lawn" when I was a kid. My house is in western North Carolina near Asheville. Moved into a new house in the middle of April. Backyard was crazy, couldn't even push a mower over it because it was so bumpy. It had nothing but weeds and crabgrass. So, I hired a landscaper to come out to till, grade and hydroseed. The front yard was mow-able, but in poor shape as well. He overseeded the front yard. This work was done in late April. (which I now know was about the worst time to do this work) Backyard 1 (pre-work): Backyard 2 (pre-work): Frontyard 1 (pre-work) In progress: Backyard 3 (after tilling, grading, hydroseed) So, 3 months+ later and the back yard is now about 75% crabgrass (nutsedge I think) and the rest is tall fescue. There are still very thin parts where there is not much of anything. The front has thickened, but still a ways away from what I want. I'm trying to get my calendar worked out for the rest of the year with regards to lawn work. When is the best time for me to try and kill the crabgrass? What products do you recommend? Sedgehammer for the sedge? I am also wondering when the best time to overseed is going to be. I shouldn't need to aerate because of the recent tilling, right? Front as of a week or so ago: Back a couple weeks ago.
