The other invasive vine I have on my property is poison ivy. There was
one vine climbing to the canopy of an oak tree that is about a 30"
diameter and very very tall. The poison ivy vine was about 3" diameter
where it came out of the ground, and was flourishing all the way at the
top of the tree. I sawed the vine @ ground level, and again about 6' up.
That was in April of 2005, and this summer the tree looks great. If you
do have Poison Ivy vines, read up on the necessary precautions before
attacking it.
