How to get rid of Poison Ivy?

[beac]

17. Thanks for the reminder about vinegar to kill off undesirables!

I had actually tried vinegar several years ago to kill PI w/limited success.

However, in our new house we have one of those weed multi-leaf-frond trees (not sure the name) growing in the dirt outside one of the basement casement windows. The previous owner was dealing w/this by just trimming it back (after clearly letting it get out of control at some point b/c the trunk is substantial.)

Yesterday, I went out there and poured a gallon of white vinegar (all I had on hand) onto the leaves and into the dirt surrounding it. Even w/last night's light rain, the plant is already dying off this morning! Hoping a few more treatments will kill it and then we can yank up the corpse.
