Composting doesn’t have to be complicated. Simply pick a shady spot for your bin and remember the four key ingredients: browns, greens, water and air. Browns are mostly yard debris like fallen leaves and woody materials chock full of carbon energy, while greens are nitrogen-rich lawn clippings or fruit and vegetable scraps. Mix these together and make sure to keep them moist and aerated by adding water and turning the compost regularly. For best results (and to deter pests), cover your bin with a tarp and bury food waste you add to the mix. Within a few months, your bin should yield a dark brown bottom layer of nutrient-rich humus.
