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!

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.

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.

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.

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.

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.

I used a lawn company till this year, my problem has always been Poa Annu Bluegrass. bought this product appplied 1 oz per gallon with my hose end sprayer results were visible 2-3 days after use. Use a sufflant also. bought the smaller size this time but will buy the bigger next year for two applications at separate times. NO MORE LAWN COMPANIES WASTING MY TIME AND MONEY!

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.

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.

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 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.

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.

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

Used product to kill bermuda grass coming up in garden and flower beds. Product works, but frequently takes multiple applications to kill the bermuda. So far, other plants have not been hurt by the product.
