Primarily, this includes soil solariazation and flaming. Some material on prescribed burning is also included, not because it is considered an appropriate control measure in home gardens, but because some of the issues have relevance to a broader understanding of weeds and their control. Soil solarization is a clean, environmentally friendly and efficient way to clean up seed infested soils prior to planting. Flaming, if done properly, can be a clean, environmentally friendly, and efficient way to control seedlings and adult plants. Prescribed burning is primary for the rejuvenation or clearing of prairies, meadows, or open fields. . .
Soil solarization is straight forward and effective.
Solarization uses trapped solar energy to raise the soil temperature to that level. Cultivate and rake the soil level, remove the large clods, and irrigate well. Wait 2 weeks for surface seeds to germinate, again cultivate and rake smooth. Give another deep irrigation and tarp with 2 mil clear plastic. Bury the edges of the plastic to give a tight seal and solarize for 4 weeks.
