Rated 5 out of 5 by from A Very Reliable Product Easiest way to use is the 'connect-to-hose' style of WBG. Since it recommends only to use 2x a year, I have had the best results applying in Mid-late April, and then mid-late October. And while it kills and controls most weeds, some weeds like Creeping Charlie should also be pulled out by hand. A good reliable product if consistently used, year after year.

Rated 1 out of 5 by from Spray Nozzle disaster! I have happily used Ortho Weed B Gone for years. Now the spray nozzle has been changed to a design the is almost unusable. Did you even evaluate the new design? Someone should be fired and never work as a product engineer again. I will not purchase again in this package.

Rated 5 out of 5 by from Does the job! I've used this product for years and have had very good results; however, with that being said, it's vital that the instructions be followed to the letter for best results. One of the big things that makes the product work well is the instruction about not mowing 48 hours before or after application. I've found that can make a big difference in itself. Another thought, don't expect any herbicide to kill all the weeds in one pass. I use a pull behind sprayer for large areas a couple of times a year and then I spot spray with a two gallon pump sprayer about once a month. Killing lawn weeds is always a work in progress. I've never had any issue with this product burning or killing any grass, even in areas where I've spilled some.

can I use concentrate in a 32 oz. spray application bottle, if so what amount?

Asked by: Rich 1007
Rich, the Ortho Weed B Gon Plus Crabgrass Control Concentrate can not be used in the 32 oz Ready- To-Spray bottles. However, it can be used in a tank sprayer or with other hose end applicators.

What time of year is best to use it? Is July too late>

Asked by: Clever
This product can be used any time weeds are actively growing, but should not be used more than twice per year. For best results use when daytime temperatures are above 45°F and below 90°F.
