Why I Put Hazelnut Shells in My Garden

I started using hazelnut shells in my garden because they help me keep the soil covered and protected. They act like a natural mulch, so my soil stays cooler in hot weather and holds moisture better after watering. I also like that they slowly break down over time, which means they can improve the soil little by little without me needing to replace them too often.

Another reason I use them is that they make my garden look neat and natural. I can spread them around plants, paths, and flower beds to reduce bare soil and help stop weeds from growing as fast. For me, that means less work and a healthier garden overall.

I also appreciate that hazelnut shells are a simple, eco-friendly material. Instead of throwing them away, I can reuse them in a way that benefits my garden. That makes me feel like I’m wasting less and doing something useful for the environment at the same time.
