My friend has an old Agave Century plant in a relatively inaccessible location on the side of his house
It's a "century" plant, about 3 feet tall and five feet wide with the spiky thorns (I don't have a picture, else I would have posted it). Sorry.
He knows I'm now an expert in poison oak, so he had asked me how to get rid of it. Apparently, today he tried to cut it with a sawsall (leaf by leaf), and the gooey green stuff made his forearms itch like hell within minutes.
Looking it up, apparently it has calcium oxalate crystals and some kind of chemical called a "steroidal glycocide saponin" (whatever that means), the first of which punctures holes in your cell membranes to allow the second access to the juicy part of your cells.
(I wonder who is the predator here.)
Anyway, he asked me HOW best to get rid of such plants without getting splashed with the green itchy gooey stuff.
Any suggestions?
