Solarization or Occultation

4
  1. Solution: Cover weedy areas with clear plastic (solarization) or black plastic/tarps (occultation) for several weeks during hot, sunny weather.
  2. Explanation: Solarization uses clear plastic to trap solar heat, 'cooking' weed seeds and soil pathogens. Occultation uses opaque coverings to block all light, preventing photosynthesis and exhausting weed seed reserves. Both methods require leaving the covering in place for 4-8 weeks.
  3. Notes: Effective for clearing large weedy patches before planting. Requires taking the area out of production for a period. Best done during the hottest part of the year.
