I noticed over the weekend that poison ivy is growing fast right now. Along with other weeds, poison ivy is also showing up in ornamental shrub and perennial borders, probably seeded through bird droppings. When growing among desirable plants, poison ivy is a challenge to control.
Three methods may prove successful. The first is to pull the vines when the soil is wet (wear gloves). The next is to sever the vine and pull out the existing vine, then cutting or spraying the new shoots as they grow. Finally, you can try to treat the poison ivy with a herbicide, while not getting it on the desirable plants, which may mean painting individual leaflets.
If you come in contact with poison ivy and are sensitive, immediately (within one to three minutes) wash with cold water and soap, which may prevent development of symptoms. Poisoning depends on direct contact with the plant’s oil, which can be picked up from bruised foliage, or from contaminated shoes, clothes, pets or other objects.
