All parts of poison sumac contain urushiol, and it can even remain active in dead plants. If you need to work with poison sumac in your garden, you should always wear protective clothing, including long sleeves and pants, rubber gloves, and boots. Thoroughly hose down your boots and gloves after you’re done in the garden, and immediately wash your clothes. It’s ideal to take a shower as well, just in case there’s some resin on your body.
Sumac Varieties
There are multiple species of sumac that aren’t poisonous and make for great landscape plants. They include:
Staghorn sumac (Rhus typhina): A shrub or small tree that grows from 15 to 25 feet tall and features reddish hairs covering its stems Fragrant sumac (Rhus aromatica): A dense, low-growing shrub at only around 2 to 6 feet tall that gives off a sweet citrus scent when its leaves and stems are crushed Evergreen sumac (Rhus virens): A medium-sized shrub at up to 10 feet tall with glossy evergreen foliage
How to Remove Poison Sumac
Poison sumac is somewhat difficult to remove, primarily because of its toxic nature. While wearing protective clothing and eyewear, start by trimming the plant down to the ground with pruning shears. Make sure to immediately bag all the clippings—never burn them. Then, spray the area with a hose to loosen the soil. Dig around the plant’s root ball, pry it up, and put it in a yard waste bag as well. Search the soil for any remaining roots, as these have the potential to sprout new plants. You can cover the site with cardboard or a tarp for at least a full growing season to smother any new plants that try to grow. After removal, be cautious when removing protective clothing and immediately wash all garments and accessories. As a last resort, you can use herbicide to get rid of poison sumac.
