Field bindweed

Field bindweed (Convolvulus arvensis) is a perennial broadleaf that has a root system that is 20 or 30 feet deep or more, making this plant very difficult to control.

This weed trails for several feet along the ground, forming a mat until it finds something to climb, such as shrubs, perennials, annuals or vegetables. It has a white or pinkish-purple 1- to 2-inch trumpet-shaped flower that is open until late afternoon, when it closes to reopen the next morning.

Field bindweed may root wherever a piece of the plant touches the soil, so if pulling, make sure to pick up each piece. Bindweed is very drought-tolerant and seems to thrive in clay soils.

You can control field bindweed by vigilantly removing the top growth from the plants. This will eventually starve out the plant, but this can take some time and requires constant removal.
