Easter is just around the corner. With eggs on my mind, I started to wonder if there were any other uses for eggshells beyond beautiful holiday decorations. As it turns out, there are quite a few.
Next time you get a carton of eggs, crack them open carefully, rinse them out and fill them with potting soil for a biodegradable seed starter packed with calcium for your plants.
If you keep chickens, rinse and grind the eggshells and feed the crushed shells back to them. The shells contain valuable calcium for your hens, just like oystershell supplements.
Eggshells contain calcium, phosphorous, magnesium and potassium. These nutrients are crucial for plant health, which means that ground eggshells make great fertilizer. You can incorporate it into your soil, sprinkle it on top or your garden beds, or add it to a watering can for a slow leech of nutrients.
