Are Peanut Shells Good for Compost?
The answer to that question really depends upon where you are. In the southern United States, the use of peanut shells as mulch has been linked to the spread of Southern Blight and other fungal diseases. While it’s true that the composting process may kill any fungus that’s being harbored in the shells, Southern Blight can be nasty, and it’s really better to be safe than sorry. It’s not as much of a problem in other parts of the world, but it has been seen spreading farther north in recent years, so take this warning into account.
How to Compost Peanut Shells
Apart from the worry about blight, composting peanut shells is pretty easy. The shells are a little on the tough and on the dry side, so it’s a good idea to break them up and wet them down to help the process along. You can shred them or simply put them on the ground and step on them. Next, either soak them for 12 hours first, or put them on the compost heap and wet it down thoroughly with the hose. If the shells are from salted peanuts, you should soak them and change the water at least once to get rid of the extra salt. That’s all there is to composting peanut shells should you decide to do it.
