“Broadleaf herbicides are most effective on spurge when the plants are young. Mature plants are can be resistant to post-emergent herbicides. A product containing 2,4-D and other ingredients such as MCPP, MCPA, or Dicamba is recommended.
Vinegar-based (20% acetic acid) or Citric Acid herbicides – considered natural organic weed killers – can be used effectively in landscape beds, sidewalks and driveways. Spray them when they are young for best results. These herbicides are not selective – they will damage any foliage they come into contact with.”
