I put the natural materials found here in the southern Sierra Nevada mountains into my garden dirt. This is a hazardous wildfire area, so I am also eliminating some fuels from my 5 acres. The grasses grow Feb.- Apr., then dry out. I put them underneath my dirt, so I don't get any grass seeds germinating. I grow plants there, by time I harvest the grasses have decomposed. I like to build soil. I don't have to till, because the soil addtions build a great loam. How is it in your garden?
