Broadleaf Weed – Poison Ivy

(Toxicodendron radicans)

Also known as Rhus radicans, Eastern Poison-Ivy, Markweed, Poison Creeper, Three-leaved Ivy, Picry and Mercury, Poison Ivy is a creeping perennial weed that can be found throughout the northeastern and midwestern United States. As with other poisonous plants in this family (including Poison Oak), Poison Ivy can cause painful irritation and severe allergic reaction upon contact with the skin.

Identifying Poison Ivy -

Poison Ivy does not typically invade mowed turfgrass and prefers shade along fences, rock walls, or in wooded areas. If you suspect Poison Ivy in these areas, do not touch it or try to pull it out by hand. Take a picture to have it identified, or ask your Scotts LawnService technician for assistance.

Poison Ivy can be a climbing or trailing perennial, forming either a deciduous woody shrub or a climbing vine with 3 leaflets. On older plants, Poison Ivy's aerial roots give the stems a hairy, fibrous appearance. Its leaflet stalks are short, except on the middle leaflet.

Poison Ivy features small, yellowish-green flowers on auxiliary panicles. This poison creeper also forms small white berries containing a single seed. These berries typically remain on the stems through winter. Poison Ivy reproduces by these seeds or by creeping root stocks and stems that root where they contact the soil.

Poison Ivy Control -

Small clusters of Poison Ivy plants can be removed physically, but only when the plants are young and lacking thick, woody stems. Gloves must be worn and no part of the plant should contact the skin.

Poison Ivy

Removing larger groupings of this poison creeper is considerably more difficult, even when using weed control methods. Because Poison Ivy can grow into other woody plants and trees, it is important to use extra caution when applying herbicides so that collateral damage to surrounding plants is kept to a minimum.

Scotts LawnService uses a selective systemic weed control program to fight Poison Ivy in your lawn, which ensures the herbicide is moved throughout the weed, killing it completely root and all. While our lawn program does not usually control Poison Ivy in landscapes or wooded areas, we recommend Ortho® MAX® Poison Ivy & Tough Brush Killer to kill Poison Ivy in these environments.
