Time Frame

• Burdock plants begin to flower in July, continuing until the first frost. Flowering burdock can spread quickly if the seeds are dispersed.
  
  

Solution

• Eliminate burdock plants without pesticides by cutting the plant at the ground level, then digging up the roots with a shovel or spade.
  
  

Other Considerations

• Place burdock plants into plastic bags and seal them tightly to dispose of the plants without risk of the seeds spreading. Alternatively, burn the plants to eliminate them once you dig them up.
