Once in a while use a garden fork (or wood, or anything) to turn them. And not long after that you can get dark, rich soil for your garden. Seriously, it is not hard!!!
If everyone were to do abit, we can all help the environment, minimize waste, and also save money (no need to buy fertilizer maaaa)
Just remember to cover it well so that flies can't get in, cats won't go poop in it and also rats won't go dig it ya.
