Eggshells, often discarded as waste, are a valuable natural resource for gardening. Rich in calcium carbonate, they strengthen plant cell walls, boost root growth, and prevent issues like blossom end rot in tomatoes.
Crushed eggshells can be used as fertilizer, pest repellent, or mixed into soil to improve structure and nutrient content. They also make excellent biodegradable seed starters—plant them directly into the ground, where they decompose and nourish young roots. Adding eggshells to compost balances acidity and enriches it with calcium, while they can also help neutralize acidic soil.
Especially beneficial for tomatoes and peppers, eggshells promote healthier, more productive plants. Instead of throwing them away, recycle eggshells to naturally enhance your garden’s growth and vitality.
