Answered by: Barbara Medford

QUESTION:

Suggestions for eradicating Poison Ivy? I have just a small growth in my backyard. Thanks -

ANSWER:

Eradicating? Isn't going to happen. Controlling? Yes, you can do that, but it's not a one-off operation. Toxicodendron radicans (eastern poison ivy) is easily and continuously spread by birds, who like the berries. They eat the berry, it's processed through their digestive system, and they return it to the earth with some fresh fertilizer, no charge. Poison ivy is very good at camouflage and disguise, as well. It needs shade and moisture, so what better place than under an ornamental bush or tree that you are watering and caring for? It can climb trees, concealing its stems in the bark, with dark green leaves that blend right in. You really can't risk using an herbicide, because there's no way to keep from zapping the ornamentals you have painstakingly planted. Some gardeners have tried "painting" a few leaves with herbicide, but this is still pretty chancy.

So, here is our recommendation. You'll need rubber gloves (like you use for dishwashing) and paper towels or newspaper, plus a plastic trash bag for disposal. Scout out the roots, and with gloves on and a piece of paper towel wrapped around the roots try to pull it all out. As you pull it out, keep the stems away from you, wrap it in paper and put it in the plastic bag. We have heard that washing skin that has been exposed to poison ivy, very quickly, in dishwashing soap will help. What we do is wash our hands, with the rubber gloves still on, in the dishwashing liquid. If you feel your clothes have come in contact with the poison ivy, take them off very gingerly, trying not to touch any of the oils from the ivy, and get them straight into the washing machine. This may sound very elaborate, but anyone who has ever had poison ivy dermatitis will tell you it's worth it.

Toxicodendron radicans (eastern poison ivy) is deciduous, but even dormant plant material can cause problems if it's touched. The best time to attack it is in the early Spring, when the whole plant should be easier to get out. It takes many different forms, although the rule of "leaves of three, let them be" still applies.
