How to Kill a Vine Weed With White Flowers

Field bindweed, sometimes called wild morning glories, came to North America from Europe and western Asia. You can find this vine weed across the United States, sometimes densely covering the ground with twining stems up to 6 feet long. The white flowers are shaped like trumpets or funnels and can grow to be pink, blooming multiple times throughout the growing season. This vine weed's root system is one of its most impressive features, growing up to 30 feet across and 30 feet deep. Unfortunately, field bindweed is perennial, meaning it will come back every year. Use multiple tactics to kill this vine weed with white flowers.

Herbicide containing glyphosate
Herbicide sprayer
Tiller

Instructions

- 1
  Wait until the fallow season when crops are not growing. This is the safest time to use any herbicide and is the most effective time to kill the weed.
- 2
  Spray a herbicide containing glyphosate if you can void spraying nearby crops. The vine weed's foliage will absorb it, moving it down to the root system and killing the roots. The root system is extensive and repeated applications of a herbicide are necessary to kill it.
- 3
  Allow the vine weed to produce flowers before spraying it again. Spray these chemicals while the flowers are blooming. "More translocated herbicide will be moved to the root system when the plant is flowering than when vegetatively growing," according to James Atland of Oregon State's North Willamette Research & Extension Center.
- 4
  Till the vine weeds multiple times during the growing season in addition to using herbicides. Wait one to two weeks after it re-emerges to till.
