I totally underestimated the resilience of Kudzu.  I bush-hogged the vineyard site, use a boxblade to pull roots and clean up.  All looked good this fall, but spring and summer has been a fight.  Every weekend is a battle to take back and kill this stuff.  Kudzu grows about 12″ in 24hrs.  With all the travel I’ve been on, by the time I get home, its several feet in length.  I’ve used roundup as much as I can, but with all the rain, it just isn’t effective.  Digging, hacking, and cutting seems to be the best course of action.  I’ve broke one hoe, and bent the other.   I’m slowly but surely winning the battle.  Each weekend I find new pockets of vines, but less and less each week.   I will win this battle!
