I brought in 10 tons of dirt to landscape my lawn. I planted Kentucky blue grass, perennial rye and fescue. When the seedlings came up, so did the imported weed seeds in the dirt to compete. As far as I know this is the only herbicide you can use at the time of seeding. It killed the crabgrass quick. In other places in my yard it killed yellow nutsedge and creeping bent grass (with 3 applications). Use a surfactant in the tank with Tenacity.

Tenacity is the best product on the market works great. Remember follow the correct amount for what you are doing, and dont forget surfactant and laser blue.

Awesome product -- killed all of the crabgrass without harming the regular lawn. Delivery was perfect and about $10 less than Amazon.

My yard borders a golf course and the bent grass constantly shows up in our yard. Tenacity is the only product I have found that will kill the bent grass and not our blue grass. Great product and good service from Do My Own.

I have a problem with creeping bentgrass in a tall fescue yard in ky. Did an online search, and read about tenacity. I tried it and at first didnt think it did anything, after about a week, my bentgrass and crabgrass and nutsedge started turning white then to brown I am thrilled that it actually worked as it did. Count me happy

Looks like this is going to be my go to application for the lawn for foreseeable future. Crabgrass was first to change color to white (applied on Tuesday, white on Saturday.) Clover definitely taking longer. About to hit the lawn with second app 3 weeks after first to we'll see how that goes, soon thereafter it will be time to do an overseed.

So far so good. I wish I would have purchased this earlier. It doesn't kill my blue grass. And also acts as a pre-emergent. I just put it down yesterday. So time will tell

Shipped very timely. Product sprayed with main target crabgrass. Product seems to be working as expected.

This was the first time I've used the product and am a believer. I bought this product specifically to treat post-emergent crabgrass. I mixed Tenacity with a surfactant and applied directly to crabgrass and it was completely dead within two to three weeks of application.

First time using Tenacity and have been using it as a post-emergent without a surfactant and have been getting great results. Label says to use a surfactant in post-emergent scenarios, but you don't have to to get results. I thought I'd give Tenacity a try as I've been overseeding with Scott's Start Fert with Weed Control that has Mesotrione in it whihc is the active ingredient in Tenacity. Great product, will continue to use.

I applied Tenacity as recommended with the Hi-Yield spreader sticker on a 20,000 sq/ft lawn. It was turning the crab grass white within days. Tomorrow is the two week mark and over half of my crab grass is already wilted and brown. The remaining has white leaves. Nutsedge seems to be taking longer to die. It's showing a much lighter green than before and some is white. I haven't seen any wilt and die off yet though but I'm confident that it's on the run. I'm thinking about doing a second application to knock out any remaining weedy grasses before I dethatch and over seed this fall. Tenacity is pricey but for how little I need to use to see results it's worth the money in my opinion.

This is the best Herbicide. Works well. I would say wait a week to see the results. Watch the YouTube videos on tenacity if that helps. Highly recommend.

This stuff is amazing! I got it for the unwanted grass and weeds and it works great! I would highly recommend. This is a very good product and now my go to herbicide.

I recently ordered Tenacity herbicide through Amazon and it did not arrive any where close to the promised delivery date. I sent it back and ordered it from DIY. Not only did I receive it promptly it was also significantly cheaper at DIY.

Mixed per instructions with surfactant and turf mark dye. Applied on mostly-weed yard freshly mowed to 3.5". Huge impact to crabgrass, clover, foxtail, and yellow nutsedge. Waiting now for it to get to roots and then I will scalp, re-spray and seed.

Apply this product according to the label and it will work great. The trick is proper mixing of chemical and surfactant and careful application to insure the proper rate is actually applied,

Tenacity is a great product. However you must give it time to work 2-3 weeks but the results are well worth it. I have had slow but good results even getting ride of common Bermudagrass. Just applied the second round, hopefully this wipes it out.

Killed everything it was supposed to with 2 applications, however it is a bit slow on the clover. Glad I bought it and will be using in the spring as a pre-emergent. I have newer construction where I spread the top soil on all 3 houses and lost a lot of the good seed to the summer Wisconsin rains last year. Now that I have time to make my yard look much better this late summer Tenacity seems to be the key for next spring and going forward!

I had a variety of weeds this summer. Tenacity is doing the job for all of them. Sprayed almost two weeks ago just two days before it rained. Most of the weeds are dying (turning white). I will have to do a second spraying for some. The second spraying is an issue of my spraying than the product. DO buy the coloring agent so you can see where you sprayed (Turf Mark Blue). I also purchased the Hi Yield Spreader Stick. Follow the instructions to the letter and you will be successful.

This site provided the best price for this aggressive weed killer. It works as advertised. Within 2-3 weeks, paper white weeds and some dying of some other stubborn broad-leaf weeds. Another application in the next day or two will set me up for a some easy over-seeding in the Fall.

Really simple to use. Applied first app to about 10000 sq ft of my lawn and I can really see the weeds turning white now. 2nd app coming soon. I would definitely recommend buying the Marker Blue however. I did not thinking "How hard can it be" you will get turned around and spray too much somewhere or loose track. I can see spots where I sprayed too much and the lawn too effect to that. I will say however the syringe is a little difficult to use as far as when trying to suck up the solution it's kinda of hard to draw up the solution.

As a post emergent, it kills crabgrass. Will have to wait and see how it does as a pre-emergent

Killed all the weeds as advertised. And you get this amazing feeling of accomplishment as the crab grass, clover and weird long grasses turn white and die. So satisfying! BTW - spend the extra $10 on the better dye. The stuff I bought was not good.

The greens keeper at our country club recommended Tenacity. They use it all over the golf course. The only downside is my lawn had more weeds than I thought! I have a lot of dead patches now - 2 weeks after application! Buts it's still so weirdly satisfying to see the weeds wither and die, even if it means the lawn looks bad for a few weeks.

Zone 9 in California with a Fescue lawn. Noticed several areas with Crabgrass starting to grow. The big box hose end spray products did not work, so I purchased this herbicide and the suggested surfactant. Applied with a one gallon pump sprayer to the visible weeds and within a few days they looked very stressed. After a week they were turning white. The Fescue does not seem to be damaged so all is good. Tenacity comes with a syringe with markings to make the proper dose a no brainer. I just filled the syringe to the marking for one gallon of water and used that amount. This makes it easy for those of us that don't regularly convert ounces of product per acre to be applied to a regular guys lawn.
