The problem with the stuff is that it spreads underground... That means that stuff like RoundUp ain't gonna work...

The way Roundup works is - you paint a little on the leaves and it's abosrbed into the plants juices. It kills the roots first, and the leaves only wilt when the roots quite sending up any fresh juice.

Wouldn't use Roundup if you paid me, though. The only place I've ever used that is in the poison ivy...

Roundup has never been recommended for poison ivy. Poison ivy is considered a woody (brush) pest, regardless of it's variable growth styles and Roundup generally will not kill it. Rouundup is for grasses.

You can't really blame the product for your failure to RTFM (apparently including the handling and safety recommendations?).
