Weeds are Round Up Resistant, HELP

WeedDisaster
11 years ago

Hi everyone. I have a backyard area that is approximately 12,000 sq ft in size (huge). The area is covered in weed control cloth and then covered with rocks. I am having a horrible time getting the weeds to die. I have been using round up (kill all weeds and grass), extended control weed and grass killer, Eliminator, homemade (salt/vinegar), etc. diluted much less than on the directions on the package (almost full strength concentrate) and still can not get the weeds to die. I have applied the weed killer by using a pump sprayer. Its a nightmare. I have also been using solarization in one area, and the weeds are growing under the clear plastic. Im at my wits end, as pulling them by hand takes countless hours. Side note: I have been using the same strength in our front yard, and kills weeds within 2 days time. So something is up with our weeds in the backyard. They just will not die!!!
