  • Smothering.
    If you can prevent light from getting to the plant by smothering with a thick layer of newspaper covered with mulch the bulblets will eventually die. It can still take a number of years.
  • Organic solution.
    Many people believe in the use of vinegar solutions as weed killers, vinegar will kill foliage, but it will not kill the bulblets under the ground. Repeated applications are needed to eventually 'starve' the oxalis. Soap mixed with the solution will help penetration of waxy surfaces on some plants.
