I bought some concentrated roundup a couple weeks ago to kill off my lawn so I could till it, rake it out and reseed. The directions say to mix 6 oz per gallon and to apply when the temp is 60 degrees or above.
The first day I mixed 12 oz per 2 gallons in a pump sprayer and applied when the temp was 62 degrees and cloudy. I saturated the lawn and waited 3 days and saw very little evidence that it was working. 5 days after the initial application, I reapplied, the same strength, on a 68 degree day and started to see a little browning after a day. Fast forward to this Sunday when I reapplied again, the rest of what I had, mixed about 16 oz to 2 gallons, on a 71 degree day with lots of sunshine following rain we had on Friday and Saturday. I still see a little more browning, but not the death of my lawn I would expect to see. Today is the 10th day following my initial application and I've gone through a $45 bottle of Roundup and my lawn still is bright green in a lot of places.
What the hell??
I'm going to contact Monsanto to let them know how displeased I am with their product. I applied it according to the directions on the package and consulted my neighbor who used to be landscaper, and we are both scratching our heads on this one. Anyone else had a similar experience? The directions say that after 10 days, the grass/weeds should be dead but yeah, they arent.
I understand how roundup works by being absorbed by the leaves. I had everything glistening wet with the herbicide and the conditions are right for my grass to be growing, so it should be sucking the herbicide down inside the plant.
