My yard is about an acre+ on the Amite river. Any time the river comes up it deposits any and all weed seeds. Within the last few years it deposited stickers/lawn burweed. These stickers have completely taken over the yard. I researched and found out picking them one by one out of yard is the only way to get rid of them. This is unrealistic for me. My question is, I am about to reseed my lawn with Carpet Grass seed. If I double up and get the carpet grass seed real thick will this drown out the stickers? Should I use a different type of grass to do this? Any suggestions is appreciated.

I feel for you. My brother-in-law owns a couple acre property with a nice house, built in pool and large, well manicured lawn and he has that crap.

He's been dealing with it for about 4 years now and still doesn't have it under control. Most of his yard is St. Augustine grass, which is a pretty thick variety, but it still pops through.

He's tried weed & feed, digging and pulling (which is a lesson in futility) and even spot treating with weed killer, but it's still there.

Wish I had better news to offer.

I just hit mine with WeedFreeZone this week. I'm going to hit it with Weed and Feed in a couple of weeks. I've had mixed results. I hate that crap.

I've heard, it's best is to lay down pre-emergent for it. It's damn near impossible to kill once its up.

The only thing has worked for me is to fertilize the shite out of everything and let the turf grass choke it out. Of course, this requires a good bit of cooperation from the rain, etc.

It isnt on the label but I used msmturf (Metsulfuron Methyl) this year on burweed in my carpetgrass and it absolutely smoked it. It was slow to show results but after about 2 weeks it was completely brown and dead. I applied the last week of March and think I got most of it before it formed the seeds (stickers).

The good thing with msmturf is that a little bit goes a long way and its cheap. I think I applied at .75oz/acre for the burweed and it cleaned up most of the other broadleaf weeds as well.

One issue with burweed is that even after it is dead, the spines are still in the turf and take a while to break down. Good luck!
