you have to remember that i am from the late 60's...... so my mind wandered with this for a little while.....
trim is close to the ground... bundle up a nice bunch.....tie the ends with a stout piece of twine and hnag until the leaves wilt.....
invite your friends over to help you strip the leaves..... close the doors and pull the shades...... bring out some wine and have a nice little party......
that's how i would kill some jointgrass......
