Eggs are packed with protein, vitamins and minerals. An average person eats 150-200 eggs per year, meaning we consume over a trillion eggs per year. The question is next. Where do all those eggshells go?
Eggshells are 96% calcium carbonate (CaCO3) crystals that are connected through proteins. Most of the eggshells are added in fertilizers or animal feed. You probably throw them in the garbage. Well, that’s why we suggest that you try these 6 ways of using eggshells.
Use eggshells to boost the calcium content of your compost. Eggshells are high surface area and small volume, meaning they will “disappear” quickly. You don’t have to sterilize or grind up your eggshells. Just add them to the pile.
You can also add crumbled eggshells to the bottom of the planting holes in spring. If you don’t like them scattered to your ground in winter, clean and store them until spring.
Calcium is important for your tomatoes and peppers as these plants usually “struggle” with calcium-deficiency.
When added to the soil, eggshells give enough calcium to your tomatoes and eggplants, and prevent blossom end rot.
You need 150 eggshells to get a cup of coarse eggshell powder. Eggshells are also great to reduce tip burn in cabbage.
2. Pest deterrent
Sprinkle crumbled eggshells around your plants to keep snails away. They won’t like the sharp edges of the eggshells, and will leave your garden.
3. Seed-starter pots
Eggshells decompose quickly, and you can use them as seed-starter pots. Clean the eggshells, and make a small drainage hole in the bottom. Fill the shells with soil, and plant your seeds. transplant the eggshells in larger pots once the seedlings grow.
4. Birds feed
Mother birds need more calcium. Bake the eggshells at 250°F / 120°C for 10 minutes. Crumble them, and place them in a feeder outside. Combine the eggshells with birdseed, suet, or mealworms. This is your way of saying ‘thank you’ to birds that keep your garden safe from insects.
The baking process is necessary as it destroys salmonella. Rinse and sterilize eggshells if you plan to use them for anything other than compost.
Even your dogs can consume eggshells. Bake the shells in your oven at 200°F (93°C) for thirty minutes, and pulverize them using a mortar and pestle. Coffee grinders work well, too. Keep the eggshells in airtight container.
5. Repel deer
Deer hate eggshells. Moreover, they hate the smell of albumin and don’t go any near to things that smell like raw eggs. Unfortunately, this method may attract rodents that like eggs.
Scatter eggshell crumbles in your garden to make it pretty and keep pests away. The white color will sure add a nice touch to your garden.
