Rated 5 out of 5 by from The Best This stuff is better than any other weed killer I have ever bought. It does tale about 10-14 days to see the magic but it happens. Kills Ivy, Poisin Ivy and anything else you want it to kill

Rated 5 out of 5 by from Patience KILLS I purchased this product last year, mixed 3 ounces of product to a gallon of water. After about 5-7 days, it looked as if it wasn't killing the weeds, and was ready to reapply, but Didn't. Well let me say that it takes, about 10-14 days to start working, and does it work. Within 3 weeks, everything was killed, and that was it for the year. Looking at the same area this year, NOTHING growing. I would use, and recommend this product to anyone, but YOU  have to be Patient, and the results will amaze you, and others that see the  fantastic job done. Great Product!

Rated 3 out of 5 by from Mix Instructions I seemed to have to mix it half again as strong as recommended to get proper killing power needed on rank weeds and thick grasses in full growth. Don't expect great results if mixed as suggested on container.

Rated 5 out of 5 by from Big N Tuff Great stuff, kills everything. be careful though as it spreads a little. if you spray a spot about 2 inches look for about a 6 inch brown spot. It is powerful. Have already gone thru a 2.5 gal jug. use it in our boat storage to keep the weeds around my boat and trailer dead and gone . do it twice a year and everything stays dead the rest of the time.

Product manual says "do not apply within 100 ft of any desirable vegetation." There are oaks, palm trees and other plants/bushes within 100 ft of every area I wanted to treat on my 6 acres so is this the wrong product to be using for residential purposes?

Asked by: doggierescue
Avoid spraying in leaves trunks or exposed roots of any desireable plants.

I have a gravel circle drive. Is this going to kill grass and weeds I may not be able to see yet, or just those post emergent grass and weeds?

Asked by: RobertsWay
Big N Tuf is a post emergent herbicide. If you want to control weeds that have not yet germinated, you will need my Gordon's Barrier Year Long Vegetation Killer. You can spray Barrier on bare ground to prevent thing from growing in that area for up to one year.

what is the mixing ratio pronto vs water
