Wow!!! I guess I can't complain any more about needing to pull the occasional yellow nutsedge.so I cut down over 500 timbers averaging height was 20' in length and had a craftsman take them all. Then I rented a mini excavator for 3 days and literally roto tilled every square inch of my yard about 3 feet deep. I ended up hauling over 17,000 pounds of roots to the dump and after all said and done my yard level dropped as much as 8" in many spots. In addition, I pulled over 200' of bamboo root from out of my sewer line.
Or to quote the movie Alien, "Nuke the site from orbit, that's the only way to be sure."bulldose the top 2 foot of soil in a 80x100 area. only way to be 100%:whistling2:
