Hanging a mesh bag filled with eggshells in your garden can be an eco-friendly and practical trick to improve the health of your outdoor space while promoting a natural environment. Here are the main reasons why:
- A Source of Calcium for Plants
Eggshells are primarily composed of calcium carbonate (about 95%), which is an essential nutrient for plants.
• Slow Release of Calcium: By hanging a bag of eggshells, you can easily crush them to enrich the soil with calcium as they decompose.
• Calcium is particularly beneficial for crops like tomatoes, peppers, and squash, which are often affected by blossom end rot due to a calcium deficiency.
- Natural Pest Repellent
Hanging eggshells can also help keep certain animals or harmful insects away:
• Against Slugs and Snails: Crushed eggshells scattered around plants create a rough barrier that deters these pests from approaching.
• Against Birds or Rodents: Some species may be repelled by the sight or smell of eggshells, signaling an area where they are less likely to find food.
- A Source of Natural Fertilizer
Eggshells contain other minerals like magnesium and potassium that can enrich the soil.
• By hanging them in a mesh bag, you can let them dry out before grinding them into powder and incorporating them into compost or directly into the garden.
