Herbicide for Vinca


Employ the use of an appropriate herbicide when gardening with vinca major or vinca minor to control spreading. Vinca species are grown intentionally in the home garden, yet they become invasive weeds in more than 50 percent of the United States. An herbicide manages the spread of vinca to reduce the threat of competition with native plant communities.


Herbicides control vinca plants, offering substantial management of invasion. For vinca minor, apply a chemical with the active ingredient glyphosate. For vinca major, apply an herbicide with the active ingredient oxyfluorfen.


Oxyfluorfen is a selective herbicide, meaning it is formulated for use on specifically selected weeds. It functions as a cell membrane disruptor. This type of herbicide kills plants on contact through the destruction of cell membranes, according to the Penn State College of Agricultural Sciences Publications. Glyphosate is a non-selective herbicide, meaning it kills any plant material it contacts. This herbicide is an amino acid biosynthesis inhibitor. These herbicides function by inhibiting normal function of plant enzymes that promote the creation of plant amino acids, the building blocks of proteins. The disruption of amino acids causes plants to cease metabolic functioning, leading to death, according to the Penn State College of Agricultural Sciences Publications.


Practice caution when applying herbicides to vinca, particularly with glyphosate. Though controlling the area of application is essential with any chemical, due to glyphosate's non-selective herbicide classification, employ careful spot treatment to prevent killing desired plants and causing further damage to your home garden.

Time Frame

You may remove vincas by hand or with a rake during the spring season; dig out as much of the plant as possible, including roots, to prevent re-sprouting. Destroy the collected plants. Best control combines manual removal followed by a chemical herbicide for effective control of regrowth. Apply your herbicide during spring whether or not you choose to begin with manual removal efforts.


Wearing gardening gloves and protective eye wear, spray your herbicide directly onto plant foliage. Avoid contact with other plants. Choose herbicides with the appropriate active ingredients formulated for use on vinca. For vinca minor, apply glyphosate in a 2 to 5 percent solution to actively growing foliage during warm weather with temperatures above 50 degrees Fahrenheit for best results. For vinca major, select a pre-mixed herbicide. Fully saturate seedling weeds that have developed four to six leaves. When in need of assistance, contact your local county extension agent. For accurate application, employ the services of a licensed professional.
