I have successfully composted behind my fence. however, i have a hill (using google think 25%grade). various plants and bushes..and in the spring lots of weeds. cutting down grasses, carex, and weeds, i wondered if i could use the cuttings as mulch, then add something that would give it a 'compost' start. it faces south so would heat up. it's certainly not a perennial type garden. cleaning it all up is exhausting. down the hill to the mower cart and thence to the compost pile. why not in place. what can i add to make it to give it the oomph that comes from compost/mulch
