Common conclusions

Wearing protective clothing, including boots and rubber gloves, pull the plant away from any surrounding growth and structures. Trim it back to the ground with pruning shears. Spray the area with a hose to saturate the soil. Wait about 30 to 60 minutes to allow the water to soak in. This will make it easier to pull up the roots. Using a shovel, dig around the root ball, prying it up from underneath. Then, with gloved hands, pull all the roots from the soil, and place them in a plastic garbage bag.

Using trimming shears, trim the plant to the ground and throw out the cuttings in a plastic garbage bag. Next, take cardboard, a tarp, or another smothering material, and cover the ground where the plant once lived. Take care to cover the surrounding area where roots could throw up new vines. Spread mulch over the smothering material, and let it sit for at least one growing season. After at least one growing season has passed, uncover the area, and dig up the roots.

Herbicide eradication works best on sunny days with little wind. Don't spray if rain is predicted within 24 hours of treatment. Prepare your herbicide according to the package directions. Some products might need to be mixed with water inside a pump sprayer. Always wear protective clothing when you're handling herbicide. It's ideal to spray the poison sumac when it's fully leafed out. This means going after it during the height of its growing season, which is generally late spring to mid-summer. If the sumac vines have engulfed a tree, carefully apply the herbicide onto the leaves to avoid damaging the tree with overspray.

Another natural method to control poison sumac plants is to cut the plant down to the stem over and over again. You have to do it repeatedly as the plant will continue to grow, every week or two. If you keep up with it and cut it quite often, it will eventually end up dying off and won’t re-sprout or grow again. This method is more time-consuming, taking up to 2 years, but there are fewer chances to get its leaves and the urushiol oil all over yourself.

Hi! I’m Sreten Filipović. I graduated from the Faculty of Agriculture at the University of Belgrade, with a master's degree in Environmental Protection in Agricultural Systems. I’ve worked as a researcher at Finland's Natural Resources Institute (LUKE) on a project aimed at adapting south-western Finland to drought episodes. I founded a consulting agency in the field of environment and agriculture to help farmers who want to implement the principles of sustainability on their farms. I’m also a founding member of the nonprofit organization Ecogenesis from Belgrade whose main goal is non-formal education on the environment and ecology. In my spare time, I like to write blog posts about sustainability, the environment, animal farming, horticulture, and plant protection. I’ve also published several science-fiction short stories.
