What Kills Virginia Buttonweed?


The scientific name for Virginia buttonweed is dioda virginiana, and it is included in the same family of flowering plants as bedstraw and partridgeberry. This family of blooming plants is known as the Rubiaceae or madder family. The southern United States are home to several populations of this evergreen plant that is indigenous to North America. The proliferation and invasion of the broadleaf plant is difficult to manage due to the fact that it is considered a weed.


It may reach a height of up to 8 inches in length and has branches that spread out horizontally rather than upwards. The Virginia buttonweed can, however, also grow vertically. The roots penetrate the ground to an incredible depth.) Their dark green leaves, which may reach a maximum length of 2.5 inches and a maximum breadth of 1 inch, grow in an opposite direction on the stems of the plant. A widespread virus is likely to blame for the mottled yellow colour that often appears on the leaves of this plant. During the months of June through August, this plant produces blooms both above and below the ground. The flower, which is white and fashioned like a star and is barely a half an inch long, has four petals and is very little. The plant is capable of producing a green fruit that is hairy and contains two seeds.


Although it grows best in damp or wet environments, such as marshes, river bottoms, and the edges of ponds, Virginia buttonweed may survive under circumstances that are similar to drought. The above-ground fruit has the ability to float, allowing the seeds to be transported to other regions through water. Additionally, this plant has a vigorous root system that may rapidly grow new roots and form rhizomes, also known as stems, that are capable of giving rise to new plants. Cutting the stems of an existing plant may potentially result in the growth of new plants. Because of this, eradicating Virginia bottomweed will be exceedingly challenging. The weed spreads quickly and may be found on residential lawns, golf courses, flower beds, alfalfa fields, and sod farms.

Hand Removal

If you have a modest infestation of Virginia buttonweed in your yard or garden, you may get rid of it by pulling the weeds out by hand. In order for this strategy to be successful, you will need to cut away the majority of the plant’s root, let the plant to get completely dry, and then burn it. Throughout the summer, you should keep a close eye on your yard for any symptoms of the weed and pull out any new plants that appear. You should be able to eradicate the weed from your yard as long as you are persistent about it.

Chemical Control

Utilizing chemical means, Virginia buttonweed must be managed and eradicated. In order to eradicate the weed, the University of Tennessee’s Extension department suggests making use of herbicides containing sulfonylurea. Choose herbicides that include either chlorosulfuron, metsulfuron, or trifloxsulfuron as one of its active ingredients. Two separate applications of the herbicide are required, the first in May, just before the weed blossoms, and the second one, four weeks later. In addition, the extension service recommends that you make use of herbicides that include a combination of three or more phenoxy or phenocy-type chemicals. On the other hand, certain herbicides might cause harm to plants that are close. Always be sure you read and carefully adhere to the instructions on the bottle.
