Project Overview
To remove poison ivy (Toxicodendron radicans), you must put on protective gear, cut it down from the base, and dig out the root system. Some use an herbicide too. This perennial vine can cause an allergic reaction in most people (and animals) if not handled properly. The rash and itch response is caused by an oily residue in the plant's leaves, stems, and roots, known as urushiol. Urushiol is also found in poison oak and poison sumac. The saying goes, "Leaflets three, let them be," but most people won't want to let this plant "be" in their garden. Removal of poison ivy is not technically challenging, but you must be tenacious and patient in your efforts to eradicate this stubborn, troublesome weed fully. When to Remove Poison IvyA dry day with no wind is the safest time to work at removing poison ivy, especially if you will be using a herbicide spray. You do not want the herbicide blowing back at you or onto your other plants, nor do you want parts of the poison ivy scattering around your area. The best season to remove poison ivy is in the springtime when the leaves are red and easy to spot. However, the plant should be addressed as soon as you identify it. Before Getting StartedThe time required to eradicate poison ivy depends on the level of infestation, and it can take months, or even years, of repeated efforts to completely eradicate a major infestation. Poison ivy is a perennial plant that grows back from the roots and often spreads by underground runners. Removing poison ivy completely might take three or four tries. Don't hurry during your working sessions: This is a toxic plant that should be handled slowly and carefully. Safety ConsiderationsDon't take poison ivy lightly, and don't assume you won't have a major reaction if you jump in to eradication efforts. Some people who have never before reacted to poison ivy can develop serious reactions after a long session of removal workâeven if the work is done carefully. And some people find that an initial reaction, even if it is minor, can make them extremely sensitive in the future. WarningUnder no circumstances should you ever burn poison ivy as a technique for disposal. The toxic urushiol can travel in the smoke for miles. Need more help?
