It takes a good long period of high heat to kill diseases, maybe less to 
kill weeds.  We are talking summertime, not winter.  It might be easier to 
just put down cardboard, like a lasagna garden.  We had a patch of johnson 
grass that I fought for years, finally put down cardboard and feed sacks and 
grew a couple hills of gourds there.  I only had to pull the johnson grass 
from the small area where the vines were planted, and it got rid of nearly 
all of it.  If he'll pile his leaves and grass clippings on the cardboard, 
it'll be camouflaged pretty quick.
