Bindweed: Convolvulus arvensis

Also known as wild morning glory and creeping jenny, bind weed is a creeping perennial. It is a noxious weed which is difficult to eradicate because of its extensive root system.

It has a vining, sprawling, prostrate growth habit and may climb by twining around fence wire or around stems of other plants. The leaves of bindweed are arrowhead-shaped. It flowers in summer; the blooms are attractive, white or pink, and resemble the morning glory.

Pulling generally is not an effective control due to the tremendous reserves in the root system, and new shoots appear soon after pulling. Regular, persistent pulling may gradually starve the root system. Shoots should be pulled as they are noticed, since all shoots (leaves) are producing food reserves. To inhibit bindweed, increase the density and competetiveness of your turf with the proper cultural practices described in CSU Fact Sheet 7.202, Lawn care.

Control

Herbicides such as glyphosate can be painted on bindweed leaves. Repeat applications will be needed. Herbicides such as 2,4-D combinations can be sprayed on bindweed foliage; repeat applications may be needed. The most effective times for herbicide application are during flowering, or inAugust/September. Always read the label before applying any pesticide.
