Controlling bindweed

Field bindweed is a noxious perennial weed that is difficult to kill because of it's extensive root system. It has distinctive arrowhead-shaped leaves and white or pink flowers. Bindweed grows along the ground until it encounters an object that it can climb, such as fences or other plants.

Controlling bindweed

Hand-pulling well-established bindweed generally does not kill it because of its root system. Herbicides such as Round-up and 2,4-D or related chemicals can be effective in managing bindweed, but killing it with herbicides takes several applications over a period of years. Late summer and early fall applications are most effective. In a lawn environment, 2,4-D and related herbicides are preferred. Round-up or 2,4-D can also be used in flower beds and vegetable gardens. Be sure to apply 2,4-D when temperatures are between 65 degrees and 85 degrees Fahrenheit and winds are less than five mph.

It is important not to spray desirable plants with herbicides because it may kill those plants. Sponging or painting the bindweed with a herbicide is best when bindweed and desirable plants are in close proximity.
