2. Eggshells: A Calcium-Rich Powerhouse for Soil and Pest Control

Do not discard those eggshells after breakfast. Rinsed and saved, they serve a dual purpose in the garden: as a superb soil amendment and a natural deterrent for soft-bodied pests. They are a fantastic source of calcium, which is crucial for preventing blossom end rot in tomatoes, peppers, and squash.

1. 🥚 Soil Amendment and Calcium Supplement

Crush dried eggshells into a fine powder using a mortar and pestle, blender, or by rolling them with a jar. Sprinkle this powder directly into the planting hole when setting out tomatoes, peppers, or other calcium-loving plants. You can also mix the crushed shells into your compost pile or sprinkle them on the soil surface around plants. As they break down, they slowly release calcium into the soil.

2. 🐌 Slug and Snail Barrier

Crush eggshells into small, sharp pieces (not a fine powder for this use). Create a wide ring of these sharp fragments around the base of susceptible plants like hostas, lettuce, or strawberries. The jagged edges are uncomfortable for soft-bodied slugs and snails to crawl over, acting as an effective physical deterrent. Replenish after heavy rain.

3. 🏺 Biodegradable Seed Starter Pots

Carefully crack eggs near the top to preserve more than half the shell. Rinse, let dry, and use a needle to make a small drainage hole in the bottom. Fill with potting mix and plant your seed. Place the shell in an egg carton for stability. When the seedling is ready to transplant, gently crush the bottom of the shell and plant the entire thing—the roots will grow through the cracks, and the shell will decompose, adding calcium to the soil.
