Culture

Garden Use
Large bindweed is a typical and widespread weed in gardens, notable for its climbing growth habit. This vine often chokes out the plants it uses as support, so it is best to remove it as soon as it is spotted. Some gardeners, especially those tending wildlife and native gardens, let large bindweed grow in the garden because of its white, big, decorative funnel-shaped flowers. It can be grown over support structures such as wire fences.

Weed Control

Large bindweed originates from Europe and West Asia. This plant is classified as a weed due to its outstandingly invasive nature, hindering the growth of other vegetation. Its resilience and rapid reproduction through both seeds and rhizomes, enable it to colonize large areas quite quickly, pushing out native plants and crops. Gardeners see it as a nuisance because it competes with desired plants for nutrients, water, and sunlight, causing substantial damage to gardens and crops. This invasion often results in decreased crop yields and additional labor and costs for management and control. In order to spread, large bindweed mainly uses its tuberous rhizomes. These intricate underground root systems spread out, allowing new shoots to pop up some distance from the original plant, which can make control efforts quite challenging.
How to Control It
The best season for the removal of large bindweed is early spring. The plant should ideally be removed before it has a chance to flower and spread its seeds. Here are a few organic and interesting methods to control its growth:
  1. Hand Pulling: Ensure that you are removing the entire plant, including the root system. If any part of the root is left behind, large bindweed could regrow.
  2. Mulching: Cover the soil around your plants with a thick layer of mulch. This will help to suppress the growth of large bindweed by blocking sunlight.
  3. Cover Crops: Plant a vigorous cover crop that can outcompete large bindweed for resources. This could be a fast-growing plant like clover.
  4. Vinegar Spray: Mix a solution of vinegar and water and spray on the leaves of large bindweed. The vinegar will help to kill the plant.
