How to Manage Weeds in Arid-Region Water-Wise Gardens

Managing unwanted vegetation generates $30 billion in spending each year, and achieving it in low-water environments requires a fundamentally different approach than traditional turf care. Desert and drought-prone landscapes rely on sparse resource allocation, meaning every stray drop of moisture invites opportunistic weeds to take root. By controlling soil exposure, tightening irrigation zones, and applying targeted chemistry at the exact right moment, you can build a resilient outdoor space that suppresses weeds naturally. Starving Invasive Seeds Through Precision Irrigation Traditional overhead spray nozzles broadcast moisture across vast open spaces, feeding buried weed seeds along with your desirable plants. Shifting your … Continue reading

Soil Solarization: An Effective Method for Weed and Pest Control

Soil solarization heats the soil by covering it with clear polyethylene sheeting during hot periods to control soil borne diseases and weeds. The technique has been commercially exploited for growing high-value crops in diseased soils when maximum daily air temperatures regularly exceed 35°C. Farmers of the Deccan plateau in India have long exploited a form of solar heating of soil, by plowing the soil to expose the subsoil when maximum daily air temperatures usually exceed 40°C and soil temperature may reach 70°C. Studies have showed that 50°C will kill almost all weed seeds. Using clear plastic makes it possible to … Continue reading
