Oh yeah - we got 'em in Washington. When We first moved here, never having seen them before, I pulled some out of the ground with no gloves. It's something you only do once!
The type we have will get over 6' tall by summer's end. Then they will lean over in a slight wind and take a swat at you when you walk by!
Most of the time I pull them with leather gloves. When a clump of them grow together, I'll spray them with -
Crossbowョ herbicide . 30 mins after spraying the leaves begin to wilt. 2 - 3 hours after spraying they lean over at ground level. The next day they are lying on the ground and pretty soon -- they are dust.:thumbsup:
