Took a week to week and a half to show signs of killing the grass. My clover looks fine.

I was going through Ortho Grass B Gon like water, spraying every few weeks to eliminate all the grass growing in my garden beds where it was impossible to weed without digging up perennials and ground cover. One spray with Grass Out Max and almost all the grass is dead with no signs of coming back after 6 weeks. I"ll have to spot treat a few areas where I either missed or it didn't get enough product the first time. Also, based on label warnings, I was expecting my periwinkle to be a little damaged from the spraying. But, it was not.

Use to kill grass in my sunflower patch. Mixed at 0.5 oz per gallon. Light spray not soaking. Killed the grass with minimal burning or setback to the sunflowers. They were about 1’ tall at the time.

Used to kill grass growing around an up through my my young arborvitae. Did an excellent job just needed to be patient. It took me two to three weeks to see the results. Applied at labeled rates for hand spraying: Clethodim - 0.33 oz to 0.65oz per gallon Non-ionic surfactant - 0.33 oz per gallon

I'm using this to control weeds on my lawn, which is not grass but mini-clover. It has really helped us create a lovely clover lawn. In fact, if is full of little white clover flowers, which will eventually re-seed the lawn and ensure a robust result. Price is right, too.

It killed all the grass with ease at a 1% V/gallon of water. And did not hurt the potatoes.

I recently bought a 16 oz. bottle of grass killer. When it arrived the post office wrapped it in a garbage bag. The bottle had leaked and was saturated with this stuff and had a very pungent odor. The bottle was missing a cap and the inner seal had leaked to the point of being almost empty. I called DoMyOwn and was told that all i had to do was send them a picture of the bottle and I would have the option of another bottle being sent or a full refund. I took the refund as I had already found another product to do the job. They were very helpful and understanding. I will do business with them again and think more people should feel that they are trustworthy to stand behind there products and service.

This is difficult, I called to make certain that this would be okay in a large flower bed, unfortunately recently planted by about a month. I then called the company, re-read the package. I realize that you cannot test every plant but species perhaps? I was told to just mix with water only which I did. Do not use around Hot Lips Salvia or Delphiniums, lost those puppies. I have not seen any kill off after a week but do still see shoots coming up in many places again.

Don't expect fast results I got indications that it was working three weeks after a HEAVY application. Don't hold your breath waiting for this to work...unless you like deep blue skin color.

This is an over-the-top grass killer, meaning it won't affect most non-grass plants so you can spray it on weedy grass that is growing in beds among desirable plants. I sprayed it on heavy infestations of torpedo grass. The first effects showed at 7 days when the tips of the grass died. After about 2 weeks most of the grass appears totally dead and there was no effect on the surrounding desirable plants. I was impressed with this product and highly recommend it.

We recently had our sod removed and replaced with Perineal Peanut and Sunshine Mimosa. I was having a problem with Crabgrass growing within the ground covers and decided to try Grass Out Max. I tested a few areas and found that Grass Out Max really works as advertised. About a week after applying the grass blades started to look a little greyish in color. Within two weeks the grass was dead with no harm to the ground covers.

Although we are in the beginning stages of a drought, and the grass that needed spraying was stressed and tough, I decided to spray the my strawberries and around my blueberry plants. At first there did not seem to be any grass that appeared stressed. Then we got a quick shower and the younger grass began to yellow and then died. The older grass and Bermuda grass have begun yellowing. This means that the Grass Out spray is trans-locating to the roots and the yellow grass will die. Even long strands of Bermuda Grass which are growing out over gravel are yellowing and will ultimately kill the host plant to its roots. Grass Out is a great product that is deadly to grass and not harmful to my strawberry plants and to other broad leaf of the same type.

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.

Tried Grass Out Max on newly planted alfalfa that had lots of grass. Took about 10 days to see results and it works really well. Also tried on Cowpeas and it is working on grass slowly. So far I am empressed with this product.

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.

So far so good. Now let's see what happens over time.

I was have issues with brome, bermuda, and johnson grass popping up in a new pollinator planting and could not use glyphosate due to damage the seedling forbs would suffer. Someone experienced in land management told me about this product and so far it has not harmed the forbs. I mixed on the lower side but it seems to be doing the job.

The product worked as advertised. Mine leaked about 4 ounces during shipping which soaked the cardboard box; I doubt the delivery guy was happy. Please consider putting this item in a zip-lock type bag prior to boxing to avoid product loss.

Had Johnson grass try to take over my sunflower plot this spring, and the Grass Out Max used with Surfactant took care of the problem!

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.

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.

First off, the included pamphlets are very detailed and you might need to calculate the proper application for your situation. All that being said, I read a review that said to use 0.4 fluid ounces per gallon of mixture with 0.35 fluid ounces of a surfactant. This calculation was correct for my application once I worked out the proper rate from the pamphlets. I have an atv mounted 20 gallon sprayer that I use to spray food plots and around the house for all my needs. I needed this product to treat a field of sunflowers for wildlife on my property. I mixed the recommended rate that I received on this website and it really worked! All the field grasses were killed with the sunflowers looking not to be scathed. The product does take some time to work so don't expect a 24 hour turn around like some herbicides promote. It takes about a week to 10 days to work. I'm very happy with this product and this website to provide the insight into the specific application for my needs. I am now thinking to use this product on my flowerbeds and garden beds that get infested with grasses after I work so hard to prepare the areas. I'm going to research the provided pamphlets to ensure I'm mixing the correct dosage but this website does provide a valuable resource with their expertise.
