How to Identify and Control Creeping Charlie
The short answer
Ground ivy, or creeping Charlie (Glechoma hederacea), is a low-growing perennial in the mint family. Identify it by square stems, round to kidney-shaped leaves with rounded, toothed margins arranged opposite each other, small purple flowers, and a minty odor when crushed. It creeps along the ground and roots as it spreads.
For physical control, dig out the existing patch and pull up all the roots and stems, because any pieces left behind will grow back. A thick, healthy lawn helps prevent it from re-establishing.
How to identify creeping Charlie
- Square stems (a mint-family trait)
- Round to kidney-shaped leaves with rounded, toothed margins, opposite on the stem
- Small purple flowers
- Minty odor when leaves are crushed
- Perennial that creeps and roots along the ground
Cultural and physical control
Dig out existing ground ivy, pulling up all the roots and stems, or the plant will grow back. Follow up by thickening the lawn so it can compete, since dense turf discourages reinfestation. Watch for and remove new sprigs from any fragments you missed.
When to escalate
Ground ivy is stubborn and can regrow from small pieces, so large infestations may need more than hand-digging. For chemical control options and the best time to treat in your area, consult your county Extension office.
