Invasives and Vine Control


Vines compete with the tree’s leaves for valuable sunlight. The
invasive exotic vine, bittersweet, will wrap around the trunk and
essentially strangle the tree by blocking the flow of food through the
bark. Vine control is always a good idea. Severing the vine kills the
vine above the cut, while the lower rooted section may resprout. Such
resprouting is usually unsuccessful in a shaded understory. An
herbicide may be applied to the cut to prevent resprouting.


Invasive species are typically from another part of the world such that
when established here have no native enemies to hold their population
in check. When left uncontrolled, they spread into natural landscapes
and replace what would grow there naturally, including tree
regeneration and other native understory vegetation. Some common
invasive shrubs found in forests are barberry, euonymous and multi-
flora rose.

Control methods include mechanical and chemical methods. Pulling
the invasives out by the roots can be effective, but extremely difficult
and labor intensive. Yearly cutting back of the aboveground stems will
keep the invasives under control, and perhaps kill them after a few
years. The most effective control method is to cut the invasive and
follow with an herbicide treatment during the growing season. An
herbicide (Roundup) should be applied to the freshly cut stub and/or
green foliage.
