Poison Ivy

Poison Ivy does not pose a threat in our gardens to out-competing the perennials or vegetables; rather, it is mainly an issue because of the reactions it causes. Poison Ivy has three leaflets that can be toothed or lobed and can often be found as a vine growing up trees or as a groundcover if it cannot grow upwards. In the fall, poison ivy turns bright red in a beautiful and colorful display. This native vine is often confused with Virginia Creeper, a vine and ground cover with leaflets in groups of five.

The issue with poison ivy is the resinous compounds called urushiols present in all parts of the plant. The unfortunate part is that you do not have to touch poison ivy to react; the compound can get on tools, clothes, pets, or even in the air if the plant is brushed, and you can have a reaction from it. Even the dead parts of the plant contain the chemical, which can become airborne if burned.

To control poison ivy, first dress the part. Cover as much skin as possible with long sleeves, long pants, closed-toed shoes, and gloves. Small plants can be pulled carefully, but herbicides with triclopyr or glyphosphate can be applied when the plant is actively growing for control. You will likely need to make multiple applications in order to achieve complete control. If you believe you came in contact with the plant, change clothes and wash immediately. Rubbing Alcohol can help remove the oils and prevent the rash from spreading.
