Customer Reviews for Grass Out Max (Clethodim Herbicide)

We have about 12000 square feet of lawn with curbing and beds throughout. Kentucky bluegrass creeping into the groundcover of the beds used to be a real problem. Then my neighbor introduced me to to Grass Out Max. He had used it the previous fall and his beds look great. He said it took about a month for it to work. I tried it and it and for the first couple of weeks didn't see much difference, but after a month it did the trick. Now just an occasional touch up application keeps the beds looking good.

Shipping could not have been faster!! I applied grass out max at 16oz per acre with surfactant on my clover. Seven days later grass turned yellow three more days it was dead.

I have two large wildflower gardens that were getting overrun by grasses of all kinds. I was real close to tilling everything in and starting over. I am so glad I tried Grass Out Max first. It takes a while but most of the grass is dying out and my wildflowers are winning. Worth every penny. I used a fifty gallon pto sprayer on my compact tractor. Also used extra in flower beds around the house. I am now my wife's hero if I wasn't already.

I used clethodem as directed on the label and it worked great. The annual grasses were dead within 2 weeks,the tough perennial grasses such as mature fescues and Bermuda will get a second treatment. This product was used on perennial beds with no side effects on desirable plants.

I used to spray mixed clover food plots. Mixed as per instructions using suggested oil to help aid in contact. Works well. Have patience it will not kill overnight. Takes about 12 day's and grass in clover plots was dead and clover was unaffected. Will save lots of time with plot maintenance.

I mixed the product with the recommended surfactant at the specified rate and got excellent results. There was no effect on my peonies and Japanese irises.

Being new to this product I was a little concerned (a lot concerned) about spraying my tomatoes wit this product but I give it a try. The first one I used it I only sprayed 1 row of tomatoes and was careful not to spray the tops of them. It didn't hurt the tomatoes and after a few days my grass was turning yellow. So I sprayed another row and was not as careful about not getting the spray on the tomatoes and again after a few days the grass was turning yellow and the tomatoes were doing good. Then I got brave and sprayed the rest of my tomatoes and sprayed grass and tomatoes and now 2 to 3 weeks later I have pretty tomatoes that are grass free. I did mix the spray as directed. I recommend this product.

I was a slight bit biased on purchasing Grass Out Max when comparing the price to the other big names out there. I thought it was worth a shot for controlling the grass takeover in my strawberry bed. One application on a dry hot day was all it took! Less than a week and the color turned and all the grass was dead.

I have a bed of Euonymus ground cover in front of my home. My Kentucky Bluegrass lawn had invaded the bed and I had tried all kind of grass killers to get rid of it and not damage the Euonymus. The only thing I managed to do was kill the Euonymus and not the grass. I was ready to kill all the ground cover and cover the bed with mulch. I came across Domyown's website and the “Grass Out Max” herbicide. I bought it and the recommended surfactant for herbicides. I used the amount of herbicide and surfactant written in one of the reviews. (“If you use the surfactant, the recommended mixing rate for one gallon would be 2 tsp of surfactant with approximately .4 oz of the Grass out per gallon of water per 1,000 sq feet.”) I sprayed both the grass and Euonymus. You have to be patient with this herbicide. I noticed after a week the grass stopped growing, but the ground cover was not affected. I noticed the grass started to turn yellow after 2 weeks and was continuing to die. It has now been 5 weeks since I applied the herbicide. The grass has continued to wither and the ground cover has grown and filled out. I don't normally do reviews, but this herbicide isn't fast acting like “RoundUp”, but it does the job and has saved me both time and money.

Although we been having lots of rain in Florida, I mixed and sprayed the grasses growing up through out ground cover beds. That grass is turning brown now and our landscape plants were not affected. I'm gonna spray over it again soon but it may not need that, I just want to be sure it's killing it. I'm thinking I'm done pulling grass out of our landscape borders from now on.

We had a nasty patch of quackgrass that pretty much took over our small strawberry patch. This product worked like a charm but took 2 weeks, so you must be patient. It did not kill the strawberry plants.

The product worked great. I used it on my food plots which had a lot of foxtail, among other unwanted grasses. After 1 week, I could see that some grasses were starting to die off, but not all, so I sprayed a second time. I probably could have been more patient, but I wanted to make sure I hit everything. 2 weeks after the first application, I really noticed the results. I bought this with the surfactant, as suggested, and I was really pleased.

Grass Out Max is just the tool we were looking for! In a new orchard planting that was previously hay field we had tons of grass intrusion even after getting a strong initial kill before planting. Started using Grass Out Max around trees and at the base of perennial berry bushes and now only have to spot treat. We love this product!

Used to eradicate some stubborn grasses from my brassica/clover plot. Took about 10 days to show full effect, but the grass is gone and my crop looks to be fine. Will use this again if needed.

I could not keep up with grasses growing in my vegetable garden, especially difficult around my onions and garlic. I used Grass Out Max with 1 oz per gallon of water in a pump up sprayer with some surfactant and total kill of ALL grasses with no harm to vegetables. I'm a true believer.

Used this product to kill grasses in our Vinca Minor (Periwinkle) Ivy bed during mid-June NW Ohio, and in about 10 days the grasses were turning yellow and brown. Used Dawn dishwashing detergent as a surficant and gave them another shot on day 11. I would definitely buy again!

I had received misinformation which was corrected with a second call to DoMyOwn. This product needs a surfactant combined with it. It works and hasn't damaged my jasmine. However, a second application may be necessary after a couple of weeks. Check with DoMyOwn regarding amounts to mix with water. A little goes a long way for homeowner gardeners.

This has been an excellent product to kill grass that invades the Junipers and other plantings where grass does not belong. It is a little slow acting, but very effective at killing the grass, without harming the plant.

Grass Killers usually take longer to work much longer than your average weed killer which you see results in 3 days if not the next day grasses are different. It's not unusual to see products like this which is grass only killer work the way they do for the length of time it takes.

Love this stuff for killing grass in my food plots. Customer service scores 100%. I had a package arrived damaged, and I called and it was fixed immediately.
