Field Bindweed (Convolvulus Arvensis)

Field Bindweed

Field Bindweed is the bane of many Colorado gardeners. It is a vine-like, creeping perennial that spreads thickly over the ground, and can quickly climb and smother desirable plants. It is also poisonous to horses. Flowers are white or pink, bell shaped, and have the characteristic Morning Glory appearance. Leaves are alternate, 1-2 inches long, and somewhat arrow-shaped, although there can be great variation in leaf shape, even on the same plant.

Field Bindweed is one of the most competitive perennial weeds in Colorado, and is very common in our area. A 2 or 3-year food supply is stored in the root system, making this plant very difficult to kill. In addition, seeds can remain viable in the soil for over 40 years. It is best to eliminate young bindweed plants before they have a chance to set seed or develop their extensive root system.

For information about herbicide control of these and other noxious weeds, contact the Garfield or Pitkin County weed control program.

A mite is currently available from the CSU Insectary in Palisade Colorado. Landowners can order mite releases directly from the Insectary for $35 per release. Call 970-464-7916 for more information. In addition, Pitkin County has a number of releases available for redistribution to Pitkin County residents on a first-come, first-served basis. Contact Pitkin County Land Management soon to reserve your mites!

Garfield County, in cooperation with the local Conservation Districts, and Pitkin County both offer cost-share programs that provide financial assistance to landowners for noxious weed management.
