- Eggshells are often tossed away without a second thought. But did you know they have a wide range of surprising uses around your home and garden? These clever ideas will make you think twice before throwing them in the trash.
If you’re searching for eco-friendly gardening supplies, natural cleaning tools, or DIY calcium supplements, this list has something for you.
Boost Plant Growth with Eggshell Fertilizer
- Crushed eggshells are rich in calcium, making them ideal for nourishing your garden.
Simply scatter broken shells at the base of plants. This slow-release fertilizer helps strengthen cell walls and encourages healthier, more vibrant growth. You can even buy organic plant calcium boosters that use powdered eggshells.
Keep Garden Pests Away Naturally
Use Eggshells for Slug and Snail Control
- Crush and spread eggshells around your garden beds to form a sharp barrier. Pests like slugs, snails, and even stray cats avoid crossing these jagged edges.
This is a great alternative to chemical pest control. Many gardeners now buy natural pest deterrents made from eggshell granules for the same purpose.
Improve Your Compost with Eggshells
- Adding eggshells to your compost pile balances the pH level and boosts mineral content. As they break down, they release calcium and other trace nutrients into the compost.
For faster composting, crush shells before tossing them in. You can also buy compost starters that include eggshell powder.
Start Your Seeds in Eggshell Planters
- Eggshells make perfect biodegradable seed starters. They’re small, natural, and filled with nutrients.
Fill each half-shell with potting soil, plant a seed, and once sprouted, place the entire shell into the ground. For convenience, some gardeners prefer to buy seed starter kits with compostable shell containers.
Use Eggshells as a Natural Household Scrub
DIY Abrasive Cleaner with No Harsh Chemicals
- Mix crushed eggshells with a bit of dish soap and water. This mixture creates a gentle yet effective abrasive scrub.
It works wonders on pots, pans, and kitchen surfaces without scratching. For easier application, you can also purchase eco-friendly cleaning pastes with eggshell extract.
Make a Homemade Face Mask for Radiant Skin
- Grind dried eggshells into a fine powder and mix with egg white for a DIY face mask. The result is a natural exfoliator that leaves your skin feeling smooth and refreshed.
This beauty hack is perfect for fans of natural skincare products. You can even buy facial scrubs with organic eggshell powder online.
Brighten Laundry the Natural Way
- Add crushed eggshells in a mesh laundry bag to your next wash. They help whiten clothes and gently lift stains without chemicals.
If you’re looking to buy chemical-free laundry brighteners, look for options that include natural calcium or minerals like eggshell powder.
Clean Your Drains with Ground Eggshells
- Ground eggshells can help maintain your plumbing. Mix them with dish soap and warm water and pour down the drain to gently clean the pipes and prevent clogs.
This method is safer than harsh drain cleaners and aligns with eco-friendly living. Some people even purchase natural drain cleaning kits with ground shell formulas.
Add Calcium to Pet Diets Safely
- Sprinkle finely crushed, sterilized eggshells into your pet’s food for an added calcium boost.
This is especially helpful for older pets or those on homemade diets. Be sure to consult your vet first, or buy calcium pet supplements made with natural eggshell powder for peace of mind.
Smooth Out Bitter Coffee with Eggshells
- Mix crushed eggshells with your coffee grounds before brewing. This reduces acidity and gives your coffee a smoother taste.
Coffee lovers who enjoy DIY hacks or buy premium brewing ingredients often use this trick to level up their morning cup.
Fun DIY Crafts with Eggshells
- Eggshells can be painted, used in mosaics, or turned into beautiful decorative items. They’re perfect for kids’ projects or seasonal crafts like Easter eggs.
If crafting is your thing, you can also buy eggshell craft kits or use powdered eggshells in texture art.
Make Your Own Calcium Supplement
- Sterilize, bake, and grind eggshells into a powder to use in smoothies or food as a natural calcium supplement.
This is a popular DIY method for those looking to buy organic calcium powder but prefer a homemade version. Always ensure the powder is finely ground and sterilized before consumption.
Help Tomato Plants Thrive
- Tomatoes often suffer from blossom-end rot due to calcium deficiency. Place crushed eggshells in the planting hole or around the base of the plant to prevent this issue.
Many gardeners buy eggshell soil additives to support their tomato plants — but homemade works just as well.
Feed Backyard Birds with Extra Calcium
- Sterilize and crush eggshells, then mix them with bird seed. This provides nesting birds with essential calcium, which is especially important for egg production.
If you feed birds regularly, consider using or buying bird food with added calcium supplements for healthier flocks.
Absorb Odors Naturally in the Home
- Place dried eggshells in a bowl and leave them in your fridge, cabinets, or near the trash can. They naturally absorb bad odors and freshen the air.
For convenience, some homeowners purchase natural odor absorbers made with eggshell-derived compounds.
