Poison Ivy Identification

Anybody who has ever experienced the blisters, swelling, and tremendous itching from an unlucky come across with poison ivy, learns rapidly to prevent it whenever possible. It grows in non-cultivated areas like along stream banks, roadways, fencerows, and woodlands. It can even make appear in your ornamental shrub or permanent borders. Hence, having the knowledge on how to recognize and control it is the best protection against unintentional contact.

Identification

The best means to recognize poison ivy or Rhus radicans is by its characteristic compound leaf composed of three leaflets. The leaflets are about two to four inches long, tedious or glossy green with pointed tips. The middle leaflet is normally bigger than the two laterals. The margins of the leaflets are changeable, appearing unevenly toothed, lobed, or smooth. The leaves are situated alternately on the stems. In contrast, Virginia Creeper, a non-poisonous vine most of the time mistaken for poison ivy, contain five leaflets shining from single point of connection.

Poison ivy can be seen in one of three figures; as an erect woody shrub, a trailing shrub running along the ground, or a woody vine. The vine is typically seen growing on trees or other objects for backup. It has aerial roots along the stem that provide the appearance of a hairy rope. Yellowish-green flowers grow in compact clusters in leaf axils, and grow in June or July. The waxy, fruits that are very similar to a berry is grayish-white, with distinctive lines marking the external surface, and is about three-sixteenths of an inch in diameter.

Control

There are three techniques that can be efficient in eliminating poison ivy in ornamental beds. They include hand pulling or grubbing; cutting the vine and then treating the re-growth with an herbicide; or integrating an herbicide to individual leaflets.

Hand pulling is most flourishing when the soil is humid. The roots can be dug and pulled out in lengthy chunks. Care should be taken to take out the whole root because the plant can re-sprout from segments of root left in the ground. Prevent skin contact by wearing gloves while you work and washing clothing and gloves right away after. The washing machine should be rinsed thoroughly next to abolish the chances of contaminating other clothing.

Vines growing on trees can be hard to pull out of the ground due to the roots might be entwined with the roots of the tree. Cut the vine at the base and cautiously pull it out of the tree. Glyphosate like Roundup or Ortho’s Kleeraway Grass and Weed Killer, a non-selective, translocated herbicide, can be integrated to the new shoots that will soon appear from the base of the old plant. This herbicide is most efficient if integrated to actively growing foliage two weeks on either part of complete bloom, in early summer.

Another herbicide that might be utilized is triclopyr. Poison ivy is hard to control even with herbicides. Neither glyphosate nor triclopyr will supply the full control from one application, and repeat applications to cure re-growth may be necessary. Other herbicide brands or formulations may be located at your local garden center. Make sure to read the label to guarantee that poison ivy is listed on the label, then follow the manufacturer’s instructions.
