Can Corn Cobs Go in Compost? Yes, they can! Although composting a corn cob takes longer than composting corn husks, the cobs serve an additional purpose even before they decompose into useable compost. Left intact, corn cobs provide air pockets in a compost pile.

Are corn cobs good for the garden?

Corn cobs and husks

Break up old cobs and bury them near the root systems of your plants. Worms are particularly attracted to corn cobs, and happy worms make for happy gardens. Corn husks break down easily and are a great source of nutrients for the soil.

How long does it take for a corn cob to decompose?

If you throw the corn cobs whole into your compost pile it can easily take up to or more than a year to fully decompose. However, if prepared properly this should only take up to 2 months, with some active compost techniques shaving that down even further.
