18 Genius Ways to Use Eggshells: Garden to Home Uses

Find tips ranging from the garden to the home.

1. Garden Fertilizer

Crushed eggshells are a great way to add calcium carbonate to your garden soil. This mineral is essential for plant growth, helping to strengthen cell walls and prevent common problems like blossom-end rot in tomato plants. Simply crush the shells into small pieces and sprinkle them around the base of your plants. Over time, the shells will break down and enrich the soil with organic matter, providing your plants with a nutrient boost.

2. Pest Control

Eggshells can be a natural deterrent for common garden pests like slugs, snails, and even cats. The sharp edges of crushed eggshells create a barrier that these pests won’t want to cross. To use, scatter the crushed shells around your flower beds, vegetable garden, or any other area where you want to keep pests at bay. It’s a simple and effective way to protect your garden without resorting to harsh chemicals.

3. Compost Enhancer

Adding eggshells to your compost pile is a good idea for balancing the pH and enriching it with valuable nutrients. Eggshells contain calcium, which helps to create a more balanced compost heap by neutralizing soil acidity. Make sure to crush the shells before adding them to your compost bin for the best results. This practice reduces food waste and turns leftover shells into a great source of calcium for your future garden.

4. Seed Starters

Use eggshells as biodegradable seed starters for your garden. Simply place eggshell halves in an egg carton, fill them with soil, and plant your seeds. The small drainage hole naturally present in the eggshell allows excess water to escape, preventing root rot. Once the seedlings are ready to be transplanted, you can place the entire eggshell in the ground, where it will break down and provide extra calcium to the young plants.

5. Household Cleaner

Crushed eggshells make an excellent, gentle abrasive cleaner. Mix them with a little soapy water to scrub tough-to-clean pots, pans, and other surfaces without scratching. The calcium carbonate in the eggshells is a great way to tackle grease stains and other stubborn messes. After cleaning, simply rinse with hot water for a sparkling finish.

6. Face Mask

Create a natural exfoliating face mask by grinding eggshells into a fine powder using a coffee grinder. Mix the powder with egg whites and apply the mixture to your face. Let it dry before rinsing off with warm water for smoother skin. The high levels of calcium and amino acids in the eggshells help to nourish the skin, making this mask a great addition to your beauty routine.

7. Laundry Whitener

Add a small mesh bag filled with crushed eggshells to your laundry. The shells help to remove stains and keep whites bright, especially when combined with a little lemon water. This method is particularly effective for whitening delicate fabrics that can’t withstand harsh bleaching agents. Just toss the bag into the wash with your clothes and let them work their magic.

8. Natural Drain Cleaner

Ground eggshells can help keep your pipes clean. When mixed with warm water and dish soap, they can scrub away residue and prevent clogs. This natural drain cleaner is especially useful in the kitchen, where grease and food particles often cause blockages. To use, simply pour the mixture down the drain and flush with hot water.

9. Calcium Supplement for Pets

Crush eggshells into a fine powder and sprinkle a small amount over your pet’s food. It’s a great way to add extra calcium to their diet, which is essential for bone health and overall well-being. This is particularly beneficial for dogs, cats, and even wild birds that may need a calcium boost for strong eggshells and healthy bones.

10. Coffee Grounds Enhancer

Add crushed eggshells to your coffee grounds before brewing. The shells help reduce the acidity of the coffee, resulting in a smoother taste. This tip is especially helpful if you prefer a milder cup of coffee but still want to enjoy the rich flavor. Plus, it’s a great way to repurpose eggshells that would otherwise go to waste.

11. Craft Projects

Eggshells are a versatile material for various craft projects. They can be painted, used in mosaics, or as unique decorations for Easter eggs. The shells can be dyed in various colors and glued together to create beautiful, intricate designs. Using them in crafts is a fun and eco-friendly way to make use of leftover eggshells.

12. Calcium Supplement for Humans

Sterilize and grind eggshells into a fine powder to use as a natural calcium supplement. Add the powder to smoothies, baked goods, or sprinkle over food to boost your calcium intake. Eggshells are composed mostly of calcium carbonate, making them an excellent, all-natural supplement to prevent calcium deficiency and support bone health.

13. Soil Amendment for Tomatoes

Tomato plants benefit significantly from extra calcium, which helps prevent blossom-end rot. Add crushed eggshells to the planting hole or around the base of the plant for a nutrient boost. This is one of the best ways to ensure your tomato plants have enough calcium to produce healthy, delicious fruit all season long.

Feeding Birds Eggshells in their Seed

14. Bird Feed

Birds need calcium for their eggshells, and you can help by sterilizing and crushing eggshells to mix with birdseed. This is a great idea for bird lovers looking to support their feathered friends, especially female birds that require extra calcium during the breeding season. Place eggshells in a bird feeder or scatter them on the ground to attract a variety of wild birds.

15. Household Deodorizer

Place dried eggshells in a bowl or container and put it in your refrigerator or cupboard to absorb odors naturally. Eggshells are porous and can help neutralize unwanted smells without the need for chemical-based deodorizers. For best results, replace the eggshells every few weeks or whenever they start to lose their effectiveness.

16. Natural Bandage for Minor Cuts

Eggshell membranes, the thin layer inside the shell, can be used as a natural bandage for minor cuts or scrapes. The membrane helps protect the wound, stops minor bleeding, and promotes healing. Simply peel the membrane from the inside of a fresh eggshell and place it over the cut, allowing it to dry and form a protective barrier.

17. Calcium-Rich Bone Broth

Adding eggshells to homemade bone broth is a great way to increase its calcium content. As the broth simmers, they slowly break down, releasing calcium and other minerals into the liquid. To use, simply add a few clean, crushed eggshells to your bone broth recipe and strain them out before consuming. This technique enriches the broth with high levels of calcium, making it even more nutritious.

18. Succulent Planters

Eggshells can be used as tiny planters for succulents and other small plants. Carefully crack the top of the eggshell, empty its contents, and rinse the shell out. Fill the eggshell with a small amount of soil and plant a tiny succulent or seedling inside. These cute, biodegradable planters are perfect for windowsills and make great eco-friendly gifts. Plus, they provide good drainage for your plants, ensuring they thrive.

By using these practical tips, you’ll not only make the most of your eggs but also contribute to a more sustainable lifestyle. Whether you’re looking to improve your compost heap, enhance your coffee, or support your pet’s health. They are a simple, effective, and environmentally friendly option.
