Customer Reviews for Q4 Plus Turf Herbicide

I was excited about purchasing this product after reading great reviews. The product works but slowly and when I mean slowly, my results took about a week to 2 weeks to start seeing weeds shrink but not completely shrink to nothing either. The weeds were still but in a diminished state albeit dieing state. On a different treatment session, if you spray too much to try to get better or faster results it WILL kill the grass too. By too much, I mean trying to put a slightly more product into the mix or spraying twice in the same area. The product also doesn't prevent near term future weeds from coming back either, just a few weeks after treatment, more weeds sprang up to take dying ones place. I was told by my gardener after treatment it was suppose to last a couple months weed free. The product was very decent and definitely better than what I'm use to using from the big box store Lowes and Home Depot but not as fast and and long lasting as expected.

I got this after reading several reviews stating it would work well for wide blade grass like weeds. I mixed according to directions, 3 Oz to a gallon. I sprayed it on a few areas and on a few broad leaf weeds. It seemed to weaken things slightly but killed nothing. I waited a little over a week and tried a second round. The surrounding grass seems to be more distressed than what I was trying to kill. Needless to say I'm very disappointed.

In the last year creeping charlie has started invading my yard and orchard. This herbicide was recommended. Read and followed application and strength directions on a perfect day for spraying. Now over a week later it hasn't had any noticeable effect at all on the creeping charlie. It did knock out some dandelions and some minor weeds, but I can get those with a cheaper herbicide. I'll try another spraying in the spring. Creeping charlie is a really tough weed to get rid of.

Easy to use and spray. Saw results on the broad leaf weeds very quickly. Killed very little crabgrass unfortunately, which was the main reason for buying this product. Overall was a little disappointed.

We are sorry to hear the product did not work as expected and are you happy to troubleshoot with you. For crabgrass it may take up to 6 weeks to completely eliminate it and may require a repeat treatment. Can you please tell us what rate you applied the product at? Have you reapplied the product since this review? What are you seeing now? We look forward to hearing from you and apologize for the delay in responding to your review.

My first application was Mid-July and sprayed over the entire (4000 sq t) yard. After a couple of weeks, minimal change was seen and, as well, there was new crabgrass growth. I re-ordered and this time applied only to the crabgrass. As of this writing, there has been marginal success (about 20%). Yesterday, I pulled a 2-gallon pail of crabgrass from the yard and still have about 75% of the yard remaining to weed.

  Expert response:
Per the product label it does state that it may cause discoloration and it is recommended to test a small area to determine the acceptability of turf discoloration. The addition of nitrogen fertilizer or chelated iron may reduce some turf discoloration.
