I have a friend who wants to clear weeds from an area but doesn't want  
to use herbicide, and I think that pulling them may be impractical.  I  
remember someone writing about using plastic and sunlight to do this.   
What are the details?  How many hours of direct sunlight would they  
need for this to work?

Thanks,
