How to Identify and Control Field Bindweed
The short answer
Field bindweed (Convolvulus arvensis) is a persistent perennial vine, often mistaken for its ornamental annual relative morning glory. Identify it by alternate, arrowhead-shaped leaves and white-to-pink funnel-shaped flowers about an inch across, with two small bracts set about an inch below the flower.
Its roots can reach many feet deep, so control is a long game. Pull or cut the vines repeatedly to exhaust the root reserves, do not let plants flower or set seed, and expect the effort to take several years of persistence.
How to identify field bindweed
- Trailing, twining perennial vine
- Alternate, arrowhead-shaped leaves up to about two inches long
- White to pinkish funnel-shaped flowers about 1 inch across
- Two small bracts about an inch below each flower (unlike some lookalikes)
- Extensive deep root system
Cultural and physical control
Pull, hoe, or cut the vines repeatedly to starve the deep roots, and never allow the plant to flower or set seed, since seeds remain viable for decades. For individual plants, complete and repeated digging can work, but every piece of the far-reaching roots must be removed. Persistence over multiple seasons is essential.
When to escalate
Because of its deep, regenerating roots and long-lived seed, bindweed frequently outlasts hand-pulling alone. For chemical control options and correct timing for your area, consult your county Extension office.
⚠ Field bindweed's roots run very deep and its seed can persist in soil for decades; expect control to take several years. For chemical options, contact your local county Extension office.
