Organic Weed and Pest Control Through Soil Sterilization
I'm actually using big sheets of newspaper on the garden paths in the flower garden to the same effect. While not sterilizing the soil, it is starving the weeds of light, and preventing germination until we can get the landscape fabric, pebbles and stepping stones to that particular potion of the pathway. I plan to try solar sterilization next year on sections that right now are lost to weeds.
Weeds, weeds, weeds....seems like I'm always in a battle with them!
