12. Nourish Soil with Egg Shells
Just as we mentioned before that egg shells are great for starting seedlings, crushed up egg shells are actually perfect for fertilizing your full grown garden. Egg shells contain amino acids and proteins that help keep the acidity and pH levels in the soil balanced. This can be essential during the dry summer months where soil moisture and quality can be compromised. What’s great about this trick is you don’t have to do anything fancy, just crush up egg shells and sprinkle them around your plants! Super simple!
