It’s a common mistake to think that you only have to worry about not touching the leaves of a poison ivy plant. Actually, all parts of the plant can cause the rash, even if it’s dead. So, if you want to tear out plants, wear heavy protective gloves and clothing when uprooting them.
Perhaps the smartest strategy is to learn to recognize the leaves and berries of these plants if they’re common in your area. Poison ivy and oak have the distinctive “leaves of three.” And if you know they’re around, wear protective clothing when out in the woods or working in the yard.
