I can't imagine what's not working for the folks that had poor results using this product. It was easy as 1,2,3 for me.
1.) cut grass weeds down (1-2")
2.) mixed according to label & sprayed
3.) watch weeds, grass and vegetation die!
I applied during the day in ideal temps and the areas I sprayed were wilted and dying by sunset! I tried several other products and none came close to being as effective as Ortho GC. The only reason I didn't give it 5 stars is because I'm waiting to see how long my yard stays clear.

Rated 2.0 out of 5.0 by Westport007 Up to a year = A couple of months
I used this product late last summer on my very long gravel driveway when weeds reappeared after my lawn guy used a similar product early summer, hence why I decided to give it a crack. Weeds slowly turned brown, which took about 2 weeks... then died. This year, June... weeds began spouting again in the same areas, along the edges and middle of the driveway. I liberally appied the product. Again, it took about 2 weeks to see results and then the weeds were gone. Here it is August and I am doing it again! I initially was concerned about over spray onto the lawn... not to worry, it will grow back in 2 months.

I use this on my rental properties in AZ as I am a PT resident I need to keep maintenance to a minimum HOAs can get nasty if you let the weeds grow. It ain't perfect but it's the best product I have ever used. Depending on the type of weeds and amount on your property it might take a more frequent application for the first year or two. I use it twice a year in Phoenix and it does work well. Get yourself a sprayer and make sure you cover the ground thoroughly.
I wish I could bring some home to Canuckistan.

I found that you need to use it full strength. Do not dilute.

Rated 1.0 out of 5.0 by Agnes Stops weeds for about 3 months
I've tried this product several times over a five year timeframe (maybe I'm just an optimist) with poor results. I carefully mixed and applied the product each time, but ended up pulling weeds 3 to 6 months later. I am headed out right now to re-treat after 4 months.
If anyone knows an effective soil sterilizer, please share this information. Thanks.

Purchased this in May and did exactly how you are to use. It did kill the weeds within a few days, but today on July 1st I see weeds from the dead areas regrowing. So they say up to a year is what I expected, well a little over a month is not a year..won't purchase again

I found that this product takes sometime to work, 7 to 10 days. At first I thought this product did not work.

Rated 5.0 out of 5.0 by Margola Love, love, the Sprinkler Cap
This is a Sweepstakes Entry Review. I absolutely love this product because it actually WORKS! The weeds are gone, gone, gone for a long, long time. I have weeds growing in my decorative rocks, and this is the only product that is long lasting.
The sprinkler cap is the easiest of all the types (hose, concentrate,etc.) for me to use. Don't ever take this product, with its sprinkler cap, off the market!
