What can I do with old nut shells?

Answered by Edward Huber

There are actually quite a few things you can do with old nut shells! Let’s explore some creative and practical uses for them:

1. Mulch: Crushed shells from various nuts can be used as an effective organic mulch for your garden. They help retain moisture, suppress weed growth, and add nutrients to the soil. Simply spread a layer of crushed shells around your plants and enjoy the benefits.

2. Potted Plant Filler: If you have deep decorative planters, filling them completely with soil can be expensive and heavy. Using nut shells as a filler can help reduce the amount of soil needed while providing drainage and aeration for your potted plants.

3. Potted Plant Drainage: Nut shells can also be used as a drainage layer at the bottom of your plant pots. This helps prevent water from accumulating and causing root rot. Just add a layer of shells before adding the soil and your plants will thank you!

4. Pest Deterrent: Some pests, like slugs and snails, dislike crawling over sharp and rough surfaces. Crushed nut shells can create a barrier around your plants, deterring these pests from reaching them. This natural method can help protect your garden without the use of harmful chemicals.

5. Fire Kindling: Nut shells, especially those from walnuts, can make excellent kindling for starting fires. Their dry and fibrous nature makes them easy to ignite, providing a natural and sustainable option for your fireplace or campfire.

6. Crafting: Nut shells can be used in various crafts and DIY projects. They can be painted, carved, or glued together to create unique jewelry, decorative items, or even small sculptures. Let your creativity flow and turn those shells into beautiful works of art!

7. Compost: Nut shells are organic materials that can be composted. However, they may take longer to decompose compared to other organic matter. To speed up the process, you can crush or grind the shells into smaller pieces before adding them to your compost pile. Over time, they will break down and enrich your compost with valuable nutrients.

In my personal experience, I have used crushed walnut shells as mulch in my garden and found it to be quite effective. The shells helped retain moisture in the soil during hot summer months and prevented weed growth. Additionally, I have used crushed nut shells as a pest deterrent around my delicate plants, successfully keeping slugs and snails at bay.

Old nut shells have numerous practical uses, from gardening to crafting and beyond. So next time you have some leftover shells, don’t throw them away – get creative and put them to good use!
