Wash any excess oil or butter from your corncobs. Oil and dairy products can turn rancid in a compost bin.
Tear up husks and chop up corncobs before adding them to the pile. Breaking up vegetable scraps helps them decompose more quickly.
Cover corncobs with finished compost. The scent of fermenting corncobs may attract flies and other pests.
Add water and a nitrogen source such as coffee grounds, dried leaves, or tea leaves to balance the pile. An ideal compost pile has a 10:1 ratio of carbon to nitrogen. Compost should feel as moist as a damp sponge, but not soggy. If possible, use rainwater to moisten your compost, not tap water, which may contain chlorine and other chemicals.
