What is this weed and how do I kill it?

Just go piss on it a few mornings in a row and it'll take care of it. I've got a large brown area in my front yard where my two boys enjoy pissing off the porch.

2-4,D maybe

You can spray something called Liberty that will bend it over and go in dry, but that will kill the grass also.

That's Virginia Buttonweed.

Thank you!

Whatever you decide to do to combat it, start ASAP. That stuff spreads fast. In my yard, it usually pops up in mid July, so I started fighting it about 2 weeks ago.

Two years ago, I didn't pay attention to it until the end of August, and it had consumed huge areas of my back yard.

This year, I walk around every 3 or 4 days and spray heavily where I find it. When it starts to dry up a few days later, I'll pull it out, careful not to pull up the St. Augustine with it. I'm hoping there's enough time for the grass to grow back in the empty spots.

Definitely buttonweed

See if you can get celsius. I spray and fertilize yards for a living. DO NOT spray round up.

First put out a pre emergence granule, then spray the celsius.

Buttonweed is some tough shite.

Handful of Scott's weed n feed put it right on top. It will kill that stuff and the grass around it will be super green for a year.

Good luck - if you decide to pull it, make sure you get it at the root. Otherwise it will spread worse.
