Need a plan
We purchased our first house last year, February of 2013. New construction with a starter lawn. Didn't water enough and large portions died. Now we have multiple types of weeds, including tall weeds covered in black seeds that are taking over. They are back to a foot high 5 days after mowing. I am quickly learning that I am helping them spread with my mower.
I am in Charlotte, NC. Rocky, clay soil. Little over a third acre. A hill that slopes from the sun is 90% good. The large majority of the lawn is in much worse shape, full sun. I don't have irrigation but will purchase multiple hoses, sprinklers and timers. I need to do something, my neighbors all have very nice lawns and I fell like the neighborhood $&$()&.
I have been told to aerate and over seed in October and do a pre-emergent in January. Is this the correct advice? Is there anything I can do now to start killing off the weeds? What type of grass should I go with in my climate? I really need the experts to help me develop an action plan. Thanks in advance for the help and please let me know what other info is needed.
