Origin and Distribution
Ground-ivy is an exotic species that was introduced by the early settlers. Now, it has been naturalized in the north of Mexico and throughout most of North America. Now, it has footprints in all states of the US except Nevada, New Mexico, and Arizona. In the United States, it occurs in all states except Nevada, Arizona, and New Mexico. The basic purpose of bringing this species into the US was its medicinal uses, where it was cultivated in garden beds only. With time it absconded from the garden beds and spread all over the US and Canada. Ground ivy loves shaded habitats in woodlands, hedgerows, roadsides, orchards, ornamental landscapes, and garden beds.
Ground Ivy-Identification
Ground Ivy is a creeping perennial herb that extends by horizontal stolon, which branches from the nodes. Usually, it grows in patches and forms carpet mats. Ground Ivy height varies between 2 to 20 inches, and its stolon could grow as long as 7 feet. An individual ramet produces at the stolon node annually and develops from an overwintering structure that contains 2-true leaves or 8-10 leaves rosette. A cooler climate fever in developing only 2-true leaves. The leaves are often round or kidney-shaped with serrated margins. Flowers are like a funnel, bluish-purple, and pretty small. It usually possesses a fibrous, and shallow root system that emerges from the stolon nodes. The best growing area is damp and bright sunny locations as well.
Ground Ivy- Propagation and Lifecycle
Ground Ivy contains clones with male-sterile flowers. Sometimes, the male-sterile clone may have both males sterile and hermaphrodite flowers. Hermaphrodites produce larger and more flowers. Generally, cross-pollination takes place between Hermaphrodite and female clones flowers. Pollinators also visit flowers, and pollination that takes place by visitors is natural. Ground Ivy produces a huge quantity of viable seeds, usually 4 per flower. Usually, seeds disperse by wind, birds, and animals. Additionally, Ground Ivys' hairy structure helps them in disseminating in air. A few seeds may go into physiological dormancy for a short period. Otherwise, the majority of Ground Ivy seeds are viable and can grow on receiving favorable climatic conditions. Additionally, creeping growth patterns also help them establish the new plants from the stolon, so their propagation in landscapes is faster.

Chemical Control
Control using Pre-Emergent Herbicide
Roundup Weed & Grass Killer
Roundup Weeds & Grass Killers combines Glyphosate with Diquat Dibromide in 18% and 0.73% ratios, respectively. Glyphosate works through leaf and roots absorption whereas, Diquat Dibromide stops the growth of plants' foliage through burning. Both of these ingredients belong to a non-selective group of herbicides that can be used at or before planting turfgrasses and garden plants given 7- days break after application.
Due to a low Glyphosate ratio, the growers need to mix 6 ounces of this product in 1 gallon of water. Otherwise, one quart is enough for 3000 square feet of Ground Ivy infested area.
Control using Post-Emergent Herbicides
Triple Threat Selective Weed Killer
Triple Threat is a selective herbicide that targets only broadleaf weeds without any suppression effects over turfgrasses and narrow leaf plants like cereals, maize, and millets. It contains 2,4-D and Propionic Acids up to 4.55% together. Cumulatively they make 9.1% of the active ingredient in this chemistry. The mode of action is both through roots and leaves absorption. The result is often delayed but kills every target broadleaf weed in 2 to 3 weeks.
Add 1.5 to 2 ounces of Triple Threat in one gallon of water for targeting Ground Ivy. For commercial application, mix one gallon of Triple Threat in 50 gallons of water to spray the targeted areas.
