How can I reuse or recycle pistachio shells?

Reuse – Practical: Use them at the bottom of plant pots to help drainage.

Reuse – Creative: They can be made into rattles (in an old tin can or cardboard tube depending on how loud you want it) or instead of seashells wind chimes.

Recycle: Smash them up a bit and spread them around the garden – to start with, the sharp edges will deter slugs and snails and eventually the shells will break down into compost and feed your soil.
