Gleochoma hederaceae, Gleochoma hederaceae, control The plant Creeping Charlie is difficult to manage. Regardless of its name – creeping Charlie, ground ivy, gill-on-the-ground, or creeping Jenny – this plant is tough to control. Glechoma hederacea is a perennial plant in the mint family that propagates by seeds, rhizomes, and stems that root at the nodes.
This European native was brought to North America by early settlers who believed it would make a suitable shade-providing groundcover. The round or kidney-shaped, brilliant green leaves have scalloped edges and are produced opposite one another on the square (four-sided) stem. On short stalks, tiny, bluish-purple funnel-shaped blooms appear in the spring.
When the plant is crushed, a pungent mint-like odor is released. Creeping Charlie grows in wet, shaded locations, such as beneath trees and bushes. If you can adjust these circumstances, it will be simpler to prevent this weed from growing. If at all feasible, improve soil drainage, water less regularly, or cut trees to let more light into the area.
- Attempt to increase turf health and density if the region is poor and the lawn is sparse by mowing frequently at a height of 2 to 3 12 inches, fertilizer as necessary for the grass type, overseeding in the autumn, and watering appropriately.
- Also, ensure that you are growing the most appropriate variety of grass for the region (shade tolerant varieties under trees).
Consider removing the grass and replacing it with shade-loving plants that compete well with weeds, such as vinca, English ivy, pachysandra, and hosta. This plant produces lavender blooms and stalks that spread through creeping. Hand-pulling creeping Charlie is possible, but it is difficult to entirely remove the large stem system, thus this may not be a feasible option in strongly infected areas.
Be sure to eliminate the plucked plants so they cannot regrow. Dethatching equipment, also known as a power rake or vertical mower, can be used to clear up bigger sections of grass afflicted with creeping Charlie. This device produces tiny wounds in the earth and the roots so that the creeping Charlie may be “combed out” using a rake.
Caution is advised, however, since this might exacerbate the issue by spreading nodes and promoting their growth into new plants. This also removes some grass, so you may need to reseed following dethatching. This should be done between mid-August and mid-September, which is also the optimal period to overseed your grass.
- Borax has been promoted as an organic control for creeping Charlie, however research conducted at the University of Wisconsin and Iowa State University demonstrates that it is often ineffective and can cause stunting and yellowing in grass and other plants.
- Borax includes boron, which is essential for plant development in minute levels but harmful in greater concentrations.
Creeping Charlie is particularly sensitive to boron, therefore adding additional boron would be more destructive to it than to grass or other plants that are less susceptible. Due to the fact that the availability of boron in the soil is dependent on soil type and pH, it is difficult to calculate how much boron should be administered in any given location.
- And there is minimal room for error: too little results in ineffective management, while too much harms neighboring plants.
- Additionally, because boron does not degrade or evaporate in the soil, frequent or excessive treatments might result in regions where no plant life can develop.
- Creeping Charlie thrives in wet, shady environments.
Postemergence broadleaf herbicides are the most effective way to manage creeping Charlie. As with any pesticide, always read and follow the instructions on the label. A weed pesticide containing salt of dicamba (3, 6-dichloro-o-anisic acid) or triclopyr is the best option for homes.
- These active components are frequently found in combination treatments, such as Trimec or Three Way Lawn Weed Killer, so check the label for dicamba and triclopyr.
- In general, 2,4-D (2,4 dichlorophenoxyacetic acid) and mecoprop or MCPP (2-(2-methly-4-chlorophenoxy) propionic acid) are the additional compounds in these mixtures.
These compounds are suitable for use on lawns, but they cannot be used in vegetable or flower gardens since many broadleaf plants are extremely sensitive to these herbicides and even little doses would cause serious damage. In certain places, it is recommended to manually pull or hoe invasive plants.
If there is more creeping Charlie than grass on your lawn, it may be simpler to start over by eradicating all plants and reseeding. Under ideal conditions, Creeping Charlie spreads quickly. Applications of herbicides should be made while weeds are actively growing. After the first frost, mid to late fall is an ideal time to apply herbicides against creeping Charlie and other perennial broadleaf weeds.
During this period, plants are actively transferring food reserves to their roots, therefore the herbicide is also transferred to the roots, resulting in improved control. The following spring, a second spray can be done, but only when the plants are in flower (April to June), when they are most vulnerable to herbicides.
- Once again, a second application may be required.
- For optimal effects, use when temperatures are between 60 and 80 degrees, there is no chance of precipitation for 24 hours after application, and there is little to no wind.
- Before and after spraying herbicides to lawns, avoid mowing the area for a few days.
Controlling creepy Charlie requires effort and is sometimes unsuccessful. Regular herbicide treatments may be required for several years to entirely eradicate the weed. It may be simpler to simply accept its presence and periodically remove the weed when it grows too thick.
Will the herbicide Roundup destroy creeping Charlie?
Utilize Roundup® Ready-To-Use Weed & Grass Killer with Sure Shot® Wand to completely eradicate creeping Charlie.
Dicamba and 2,4-D may have comparable effects on the weeds they are sprayed to, however they differ significantly in a number of ways: (1) dicamba suppresses tougher weeds than 2,4-D, and it is more effective on problem weeds such as Canada fleabane and wild buckwheat; (2) fewer weeds have been found to be resistant to dicamba than 2,4-D; and (3) dicamba is less toxic than 2,4-D.
How can I prevent the spread of creepy Charlie among my neighbors?
Like all other plants, creeping charlie need sunshine to survive. Eliminating the weed’s exposure to sunlight will destroy it. While it may seem laborious, it may be eliminated by securing cardboard with pebbles. This procedure requires patience, since it might take up to two weeks.
