Turfgrass's Least WANTED Weeds - Bindweed

September 24, 2019

Type

A broadleaf perennial that is one of the most difficult to control and persistent weeds in landscapes and crops. Its strong root and rhizome system prevents the possibility of removing the weed through cultivation, and in most cases, it actually makes the infestation worse. Its seeds have can be viable for up to 60 years. It’s important to control this weed early, because its roots can reach up to 20 feet. It is considered to be one of the most noxious weeds because of it’s yield-robbing practices in crops and landscapes.

How to Identify

This weed has winding and twining stems that grow along the ground up to 6.5 in length and often get wrapped up in other plants and structures. The flowers are bell-shaped, with white to pinkish petals. Leaves grow alternate and are arrow-head in shape.

Where it Grows

This plant can flourish in sun or shade and is extremely drought-tolerant. It’s found in fields, turf, farmland and residential areas.

How to Manage

It’s recommended to use herbicides technologies like Lazer® to help prevent the weed from growing before it emerges. Herbicides can also be used after the weed has been established, but it’s more difficult. It’s especially difficult if herbicides are not used, as pulling the weed will only result in regrowth, as the roots are left in the soil and the plant regenerates within 2 weeks.
