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.
I don't have that email anymore...what did we decide that was- henbit?
Anyway, you can apply broad leaf weed killer right now, but since the stuff is well established it may not be as successful. Doing so in the spring and early summer is usually more effective because the plants are not as tough.
Roundup is SYSTEMIC
. It kills everything, grass and broadleaf weeds, so don't spray it in your yard becaue you will end up with dead spots everywhere you put the stuff. There are some sprays that say they don't kill grass, in which case they are broadleaf herbicides. With a large yard, it's expensive to do it that way, but you could apply now.
Aerating and overseeding are great ideas. I posted my opinion earlier about doing the overseeding while there is still some warmth, like late summer so that you will get germination and growth for the fall (which is when cool season grasses thrive). Aerating, I do that later, after some rains have shown up and softened the yard. Makes the job a lot easier for you and the aerator.
