How to Use Eggshells in Gardening

🥚 How to Use Eggshells in Gardening [Complete Guide]

You can use eggshells in gardening as a natural fertilizer, pest repellent, compost booster, and seed starter. Crushed eggshells add calcium to the soil, improve drainage, deter slugs and snails, and reduce waste in an eco-friendly way.

🌱 Why Eggshells Are Good for Gardens

Eggshells are 95% calcium carbonate — an essential nutrient that strengthens plant cell walls. They also contain trace minerals like phosphorus, magnesium, and potassium, making them a powerful organic additive for your garden.

🔟 10 Smart Ways to Use Eggshells in Gardening

1. 🥄 Crush and Sprinkle for Calcium Boost

Crush dried eggshells and sprinkle them around your plants. This slowly releases calcium into the soil — especially helpful for tomatoes, peppers, and eggplants, which are prone to blossom-end rot.

2. 🐌 Use as a Natural Pest Deterrent

Crushed eggshells act like tiny shards that deter soft-bodied pests like slugs, snails, and cutworms. Create a rough barrier around vulnerable plants.

3. 🌿 Mix into Compost Pile

Eggshells balance acidic materials in compost and add valuable minerals. Rinse before composting to avoid attracting pests.

4. 🌱 Start Seeds in Eggshell Cups

Use half eggshells as biodegradable seed-starting pots. Add soil and seeds, then transplant the whole shell into the ground. The shell decomposes and enriches the soil.

5. 💧 Improve Soil Drainage and Aeration

Mix ground eggshells into heavy or clay soil. It helps loosen the structure and enhances root health.

6. 🌼 Add to Container Plants

Place crushed shells at the bottom of pots to boost drainage and prevent waterlogging. They also release calcium gradually over time.

7. 🧪 Make Eggshell “Tea”

Soak crushed shells in water for a few days. Use the calcium-rich liquid to water plants — especially helpful for tomatoes and roses.

8. 🐔 Feed to Chickens for Stronger Eggs

If you keep backyard chickens, dried crushed eggshells make a natural calcium supplement for them, completing the cycle.

9. 🐛 Use as Compost Worm Bedding

Eggshells help maintain pH levels in worm bins and provide grit for worm digestion.

10. 🔄 Reduce Kitchen Waste

Using eggshells in your garden reduces landfill waste and supports a sustainable, zero-waste lifestyle.
