Invasive Vines

Long Island is home to both native and non-native vines. For instance, our native poison ivy is considered noxious by many, but it is only so for people who suffer from rashes after touching the leaf, vine or root. Animals don’t have the same reaction, and in fact, the berries are a good food source for them. Poison ivy is listed here among the non-native invasive plants because it often grows alongside the truly invasive plants such as oriental bittersweet, English ivy, porcelain berry, honeysuckleJapanese wisteria,  winter creeper,  and kudzu, and could easily be touched or brushed against by someone attempting to remove one of these non-native species.

Another native vine is wild grape. While the berries are a feast for birds, the vines can bring down limbs and eventually kill trees by their dense leaf cover over the canopy, shading sunlight from their host trees. The best time for severing vines from trees is late fall through early spring when other plants, which could impede access, are dormant. Click Vine Removal for details.

Soon after removing vine roots, cover the ground with mulch (a thick layer of leaves) or replace them with native, shade loving plants (plugs or seeds) such as white wood aster Eurybia divericata, and then mulch.

White wood aster is a hardy, fast growing, beautiful shade loving flowering perennial that also serves as a weed suppressant. It self-seeds, blooms throughout September, is a source of nectar and pollen for native pollinators, and native birds feast on the seeds. Click Native Plants in Recent Posts.
