Is it safe to apply inside trees drip line?
Asked by mozgheib June 22, 20192
AnswersFor years I have sprayed inside the drip line. Never an issue. If you have flowers under your trees as my wife does, use a hand sprayer for this area, it will work fine on your weeds.
I am wondering if I apply early summer where temperature is less than 90 the day I am applying is...
Asked by mozgheib June 22, 20192
AnswersI would think so. I applied mine at a temperature of 85 and had no problems. I would not apply in the middle of July when the temperature is constant.

Worked as expected !

Customer review from ortho.com 
Easy to use , effective weed control product. it can be used in a pump sprayer but I used the Ortho hose end sprayer ( screwed right on it ) for my application , I got my whole front yard sprayed in less than 20 min start to finish. The fun part was waiting for the weeds to die . As you can see in my pictures (1 week later ) It did work ! [This review was collected as part of a promotion.]

Customer review from ortho.com
This product has been around for a while and honestly I don't want for them to make it any different It works if you have every tried it there is a variety of options you have you can pour weed killer in your Ortho dial and spray and set your dial or you can buy the weed killer with a ready hose connection. But the best yet with the design at the top of the bottle take the top of your Ortho Dial and Spray and place it on to the top of your Weed Be Gone Concentrate set the dial and have at it ` [This review was collected as part of a promotion.]
Weed B Gon Weed Killer Concentrate for the Lawn
December 18, 2017
Customer review from ortho.com
This Weed B Gon product comes in a concentrate and can be applied using a dial in sprayer or you can mix it in a tank sprayer. You need to make sure you follow the guide that's included on the back of the bottle so you what is the dilution rate for the type of lawn you have.
I am using this in a southern lawn and on my dial in sprayer, I set it to 1oz. Then just pour the concentrate into the sprayer, and connect it to the hose. Pull the trigger and the a mixture of water and Weed B Gon product will be applied to your lawn. The nice thing about this product is it will not harm your lawn.
I find this product easy to use and I can treat my lawn very quickly with the dial in sprayer. I have had good results with this product. [This review was collected as part of a promotion.]
Ortho Weed B Gon Concentrate really works!
December 11, 2017
Customer review from ortho.com
My husband and I take pride in our small lawn and have tried many products to rid it of weeds. We have particular problems with dandelions and clover, which seem to migrate from the neighbor adjacent yard. We had read and heard of Ortho Weed B Gon so were excited to try this product on our problem areas. We got our neighbor's consent to spray it not only on our yard but their property as well. This product worked quickly and killed both the dandelions and the clover, but not the grass! The one bottle treats up to 16,000 sq ft, which was more than enough for our small spaces. We are very pleased with the results- this product really works! [This review was collected as part of a promotion.]
The label said for Southern Lawns, but it not only killed weeds but all our grass.
December 11, 2017
Customer review from ortho.com
On November 8th I put down Ortho Weed B Gon and followed the directions on the label and sprayed it on my lawn with the ortho Dial N Spray. The grass gradually started to die. I did not use all the product there is still some left in bottle. I live in a gated community with a HOA and they have rules and regulations on how the grass must be maintained. I went out and bought several bags of rye seed to bring some green grass back quickly. One of my neighbors commented that i usually I have the best lawn and asked what happened. He also said that the HOA only allows St. Augustine grass and not Rye grass. However, You cannot buy St. Augustine grass seed only sod. Not happy with this product. I do not think it should be used on the lawns. Please see attached pictures. This is the first time I put in a poor review of a Scotts product. I have been using Scott's products for over 40 years. I think Scotts have the best products for lawn care. I was very surprised that this product was so disappointing. [This review was collected as part of a promotion.]

not that good as it says.

not that good as it says.
Response from Ortho TeamOctober 8, 2020
We apologize that you didn't get the results you expected after using Ortho Weed B Gon Weed Killer for Lawns Concentrate. This product will control listed weeds when applied according to the label directions. This product take 2-4 weeks to completely kill weeds. However, it has proven to be much more effective than faster-acting weed controls. Mowing 2 days before or after application reduces leaf surface and plant's ability to absorb the herbicide. We do have a product guarantee that covers all of our products that we would be happy to extend to you. We would like to discuss this issue more with you so that we can extend to you this guarantee as well as to learn more about this issue. At your earliest convenience, please contact us and refer to your review to see what can be done. We can be reached at 877-220-3089.

Mixed to specified ratios and spread as instructed. All weeds and clover are still going strong. Not very effective. Will try another round but not holding out much hope.
