Peanut Shells as Mulch

Resourceful gardeners are always looking for ways to save money in the garden, including using recycled organic materials as mulch. You may have heard of some gardeners using peanut shells as mulch.

At first thought, that might seem like a good alternative. Peanut shells are affordable and fairly easy to get in Florida. They also have high amounts of nitrogen and last for a long time before breaking down. However, peanut shells can carry certain fungal diseases and nematodes, tiny worm-like pests that can feed on the roots of your plants.

So if you're looking for an affordable, recycled mulch, it's better to skip the peanut shells and instead use fallen leaves or recycled yard waste from your utility company.
