Poison ivy is one of the most dreaded landscape weeds among gardeners and it is growing nad thriving now.\u00a0 If you have ever experienced the red, itchy, blistery rash that goes along with this weed, then you understand a gardener\u2019s disdain for this plant.\u00a0<\/p>\n\n\n\n

So how can you tell if it is poison ivy?  The old saying goes \u201cLeaves of three, let it be.\u201d  That is a good starting point, but just because a plant has three leaves, it may not automatically be poison ivy.  <\/p>\n\n\n\n

According to Dr. Mark Czarnota, UGA Weed Specialist, poison ivy can grow as a vine or a shrub, with compound leaves composed of three leaflets and arranged alternately on the stem of the plant.  Dr. Czarnota notes \u201cPoison ivy leaf shape and texture is highly variable. Leaves with different shapes may be found on the same plant or on plants near each other. People may incorrectly identify poison ivy when observing a poison ivy plant with an unusual leaf shape.\u201d  In any case, following the \u201cleaves of three, let it be\u201d motto can be good advice for avoiding contact with poison ivy.  <\/p>\n\n\n\n

That said, people may incorrectly identify poison ivy when observing a poison ivy plant with an unusual leaf shape, he said. In any case, the \u201cLeaves of three, let it be\u201d motto is good advice to use to avoid contact with poison ivy.<\/p>\n\n\n\n

But people frequently confuse poison ivy with other plants in the landscape. One of the main plants that people confuse with poison ivy is a vine known as Virginia creeper. It is a native vine that normally has five leaflets \u2014 but can have three to seven leaflets \u2014 emanating from a central point. It has a weedy growth habit and grows in similar habitats as poison ivy.<\/p>\n\n\n\n

Boxelder tree seedlings can also look suspiciously like poison ivy. Boxelder seedlings are young trees with three leaflets on a woody stem. But boxelder leaves are arranged opposite each other on the stem, while the leaves alternate on poison ivy. Neither of these plants have the same itchy effect as poison ivy, but the challenge is knowing what\u2019s what! <\/p>\n\n\n\n

Poison oak is not as common in Georgia landscapes as poison ivy. According to Sydney Park Brown with University of Florida Institute of Food and Agricultural Sciences Extension, poison oak is a low-growing, upright shrub that is about 3 feet tall. It is found in dry, sunny locations and does not grow in heavy shade. It is similar in appearance to poison ivy \u2014 it has three leaflets \u2014 but those leaflets are always lobed. Whether or not you can tell poison oak and poison ivy apart, it is best to avoid both.<\/p>\n\n\n\n

After you have positively identified poison ivy, there are several ways to control it in a landscape setting. If the poison ivy pops up in a lawn or other area that can be mowed, the easiest thing to do is to mow it down. Czarnota notes that keeping it mowed will eventually eradicate the vines. <\/p>\n\n\n\n

When herbicides are needed to control a larger area of poison ivy, follow the instructions outlined in UGA Extension Circular 867-10, \u201cControlling Poison Ivy in the Landscape,\u201d which you can find at www.extension.uga.edu\/publications<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"
