Is poison ivy hairy?

Note that poison ivy vines are “hairy”—they're covered in thin roots that help anchor the plant to the thing it's climbing. In fact, another one of the many rhymes associated with this plant is “Hairy rope, don't be a dope.” A few other vines have a hairy appearance, but most of our native vines don't.

How do you stop sumac from spreading?

Prune off new sumac growth with clippers or loppers when it moves beyond the space you allot it in the garden. Prune just after the plants finish flowering in late summer. Chop off trespassing suckers, shoots and stems as close to the ground as possible. Remove and burn the detritus.

Wash your skin in soap and cool water as soon as possible if you come in contact with a poisonous plant. The sooner you cleanse the skin, the greater the chance that you can remove the plant oil or help prevent further spread.
