Weed Control

Beggarticks hails from the tropical and subtropical regions of the Americas. Being classified as a weed, it has a rapid growth and robust reproductive capabilities; it easily multiplies via an abundance of seeds that can cover great distances, thanks to their barbed structure which attaches to clothing or animal fur. To make matters worse, this plant is incredibly hardy and can shrug off adverse conditions. These characteristics allow beggarticks to spread quickly, suffocate other plants in their vicinity by outcompeting them for resources, and be extremely hard to eradicate. While beggarticks isn't particularly harmful or toxic to humans or pets, it poses a significant threat to gardens and agricultural fields due to its rapid spread and resource-demanding nature. Its primary mode of dispersion is through its seeds, which are readily carried by wind, water, or animals contributing to its undeterred spread.
How to Control It
The best season for removal of beggarticks is during the late spring to early summer period, before the plant has had a chance to set seeds. This will prevent its potential rapid spread throughout the garden. Here are few organic methods to control or remove beggarticks:
  1. Hand Pulling: After a good rain, soil tends to be softer and it is easy to pull beggarticks out by hand, ensuring to eliminate root as well.
  2. Smothering: Use a layer of landscape fabric, cardboard, or plastic to smother beggarticks. Ensure it covers the whole area where beggarticks is growing. Leave it there for a full growing season to suffocate the plant.
  3. Vinegar Solution: Prepare a solution containing one part vinegar and one part water. Spray it directly on the beggarticks to burn the plant and cause it to wilt.
  4. Regular Mowing: Regularly mow the lawn where beggarticks is growing. It cannot tolerate frequent mowing and will die over time.
  5. Boiling Water: Pour boiling water directly on the beggarticks. The high temperature will kill the plant and surrounding seeds.
