Sun Deck,
(southern Dayton, OH)
I sent you pictures in the Spring of weeds (purplish) that were popping up all over in my grass in the back of our yard. They continued to grow throughout the Spring. The flowering eventually died off, but the weeds still exist to this day and spread over the entire back of our property even after using a weed/feed application and a 2nd application in the Spring. I don't know how to stop them from growing / get rid of it. I was going to aerate the yard towards the end of August and overseed (is that too late around here?). I'm also going to be spraying other weeds that have crept up in the yard. Do you think Round-Up or some other spray that advertises being able to get rid of weeds without harming the grass would get rid of all of the weeds I have in the back of my property, and how long should I wait after applying all of that spray to do the overseeding / aerating? I'm hoping to walk out my backdoor next Spring to see a nice backyard full of grass and free of these weeds that currently blanket the back of my property.

Worse case scenario, I hire a lawn company for next year to get this straightened out because I don't want it expanding any further than it already has.

Thanks for any help / advice in advance.
