Creeping Charlie Weeds With Purple Flowers

Creeping Charlie, also known as ground ivy (Glechoma hederacea), is a common perennial weed that can become quite invasive in gardens and lawns. It is characterized by its round, scalloped leaves and small funnel-shaped purple flowers, which typically bloom in the spring.

Identification

Leaves: Round to kidney-shaped with scalloped edges.
Growth: Forms dense mats on the ground that can spread quickly.
Stems: Square-shaped and can root at the nodes.
Flowers: Small, funnel-shaped, purple or bluish, and typically bloom in clusters.

Management and Control

Cultural Control

Improve Lawn Health: A healthy lawn with vigorous turf grass can outcompete creeping Charlie. Regular fertilization, proper mowing, and adequate watering can promote this.
Manual Removal: This can be effective for small infestations. Ensure you remove the roots as well, as any pieces left behind can regrow.

Chemical Control

Herbicides: Products containing triclopyr or dicamba (often mixed with 2,4-D) are effective against creeping Charlie. Be sure to follow all label instructions and consider the impact on desirable plants.

Note: Herbicides are typically most effective when applied in the fall, but spring applications can also work when the plant is actively growing.

Natural Control

Mulching: A thick layer of mulch can suppress creeping Charlie in garden beds.
Vinegar and Salt Solutions: Some gardeners use household vinegar and salt mixtures, but these can also harm desirable plants and alter soil pH.

Preventive Measures

Maintenance: Regular lawn maintenance and monitoring for early signs of infestation can prevent creeping Charlie from becoming established.
Barriers: Physical barriers can help keep creeping Charlie from spreading to certain areas.

Environmental Considerations

Always consider the environmental impact before choosing a control method. Herbicides can affect non-target plants and wildlife, so use them cautiously and responsibly.

Creeping Charlie can be a tough weed to manage, but with consistent effort, it’s possible to control and even eliminate it from your lawn or garden.
