I'm a bit late here but like Shagaroo said, don't use glyphosate since it's a non-selective herbicide, i.e. Roundup. Pulling is probably the best option but there are some specialty herbicides that will take of it. They are generally pretty expensive relative to weed-b-gone and you have to be a bit more careful in applying them. I'm currently "experimenting" with one named Tenacity and it's been working pretty well on some stubborn weeds. It's also doing a number on my crabgrass...did I light spot spray last Thursday and the crabgrass is already bleached white (Tenacity prevents photosynthesis). I have used this Ortho Crabgrass stuff in the past on other stubborn things. You have to apply it carefully or it will kill grass as well as the weed. That's why I hit an inconspicuous spot... if it works, I'll continue with the rest of the yard. If it doesn't, I'll just wait. I have *WAY* too much of this stuff to pull it. I'd rather just let it die over the winter. But it's only July and if I can get rid of it now, that would be great. I'll keep Tenacity in mind. Where did you get it?

I bought the Tenacity from Amazon. Some specialty stores may have it but Amazon was just easier. I plan on getting an early start on weeds every year but it never happens...then they go to seed and the pattern starts again the following year. I'm usually too lazy (or cheap) to get a good pre-emergent barrier down to prevent the seeds from growing.

I'm usually too lazy (or cheap) to get a good pre-emergent barrier down to prevent the seeds from growing. I'm the same way. I say I'm going to pre-treat with Halts but my luck has been hit-and-miss. I also used to have a dog that would occasionally kill the grass with his toxic pee so I would use EZ-SEED in some spots... I would not be able to do that if I used the Halts. But there is a middle ground: get the lawn started in the spring and use EZ-SEED in any spots that are bare and then before it gets into the wild part of the season... use a pre-emergent. Hell, it's built right into the fertilizer so instead of using TURF BUILDER, just use the one with Halts. It's easy and yet... I sometimes don't do it. It will be a common practice here now.

So I decided to take control of this thing. In the spots where I hit this stuff... the weed appears to dislike the Crabgrass Control product from Ortho. It has started to turn brown and curl up a bit. So I hit some other spots and it's looking good. I also went out and found a fertilizer with a pre-emergent and I laid that down late last week just to prevent any further issues. As long as the grass has had some rain (or sprinkler) within 24 hours of applying the Ortho, you're good to go. We're supposed to get more rain this week and the stronger the grass is, the less-likely it is that the weeds will prosper.

Just here to point out that my lawn is essentially all weeds now. I haven't touched it for over a month, not even mowed. It's been hot and extremely dry here and there's been a watering ban going on. There are a few shady spots that are tall but mostly it hasn't grown for 6 weeks, except for weeds. I'm getting a service next year. i can never keep up with the treatments.

When the lawn is healthy and you're getting rain, the lawn is your best way to control weeds because a healthy lawn will just squelch them out and keep them from growing. When you get into your hot & dry run (we get it every year... 90s and sun, no rain), the lawn weakens and allows weeds to take over. Using the pre-emergent in the spring is one way to keep the weeds out. Obviously a irrigation system helps too. There was an irrigation system here when I moved in and it helps but it's basically just keeping the lawn on life support. It will look just slightly better than a lawn without a sprinkler and it will rebound faster and look better quicker if you start getting some rain but that's about it. I actually started pulling some of this stuff out by hand yesterday. Filled two old 6.5 gallon brewing buckets with weeds I pulled out by hand.

So, for future reference, B2000 was correct... pulling it out is probably the best option. I had some time on a weekend maybe 2 weeks ago and I went out to a spot in the backyard and just started pulling it out. It comes out pretty easily but you always wonder if you got the whole root and if not... you know it's coming back. But in that spot the weeds did not show up again. Conversely, in some spots where I used the crabgrass control product from Ortho... it did wipe out the weed but I also have brown spots where some grass was taken out too. It sounds like Plan A is to put down a pre-emergent so you don't have this issue, Plan B is to yank it out, preferably before it gets out of hand and Plan C is to hit it with the Ortho product knowing you might have some collateral damage.

Over the last several weeks, I've filled 1 lawn/leaf bag (and starting on a 2nd) with crabgrass that I've been pulling out of the lawn by hand and for bigger clumps, a weed/dandelion puller. Slow, painstaking work, but with the limited success I've had with post-emergent weed treatment, it was the only option I could see.
That said, the lawn is starting to look loads better where the crabgrass got yanked out. The lawn itself is slowing starting to fill in those spots on its own. Overseeding is on the docket for late September, but for now, the crabgrass is slowly being brought under control.
I also had good luck with a pre-emergent I put down back in early March, before St. Patty's Day, and I will use it again next spring.

Hopefully sometime soon.
