Identifying Ground Ivy and a Plan for Dandelion and Creeping Charlie Control

Weed Identification

The “vine with purple flowers” is almost certainly ground ivy (creeping Charlie), not chickweed. Key traits: square stems, opposite kidney‑shaped leaves with scalloped edges, minty odor when crushed, and small funnel‑shaped purplish‑blue flowers April–June. It thrives in shade, moist, fertile soil and spreads by creeping stems that root at nodes.

Cultural Management

• Mow high (2.5–3 in.) to shade out creeping stems.
• Reduce shade by pruning tree branches.
• Improve drainage if soil stays wet.
• Hand‑dig small patches, removing all roots and stolons.

Herbicide Options

Ground ivy is tough; best control comes from fall (mid‑Sept to late Oct) or spring (when actively growing) applications of a three‑way broadleaf herbicide containing 2,4‑D, MCPP, and dicamba (e.g., Trimec, Weed‑B‑Gon Max). Triclopyr‑based products also work. Spot‑treat to minimize damage to desirable plants. For dandelions, a selective 2,4‑D spray (Weed‑B‑Gon) applied in fall gives excellent results.

Long‑Term Outlook

Ground ivy was once planted as a shade groundcover. A thick, well‑maintained lawn is the best defense. Overseed thin areas in early fall with shade‑tolerant fine fescues to outcompete invaders.
