Here’s why you want to hang a mesh bag of eggshells in your garden

1. Natural Pest Deterrent

One of the main benefits of hanging eggshells is that they act as a natural pest deterrent. Slugs, snails, and other soft-bodied pests avoid crawling over sharp or rough surfaces. While scattered shells on soil can work, a hanging mesh bag creates a larger, more visible barrier that discourages unwanted visitors.


2. Slow-Release Nutrients

Eggshells are rich in calcium, which plants love. By hanging them in a mesh bag, the eggshells gradually break down in the rain and sun, slowly releasing nutrients into the surrounding soil. This is particularly helpful for plants prone to blossom-end rot, like tomatoes, peppers, and eggplants.


3. Bird and Wildlife Repellent

Some gardeners find that a hanging bag of eggshells helps keep birds and small animals from digging in soil or eating seeds. The unusual texture and appearance can discourage curious nibblers without harming them.


4. Eco-Friendly and Budget-Friendly

Instead of tossing eggshells into the trash, you’re giving them a second life in the garden. It’s a zero-cost, environmentally friendly solution that reduces waste while improving your plants’ health.


5. Easy to Make

All you need is:

  • A handful of clean, dry eggshells
  • A mesh produce bag, netting, or old nylon sock
  • String or twine to hang it

Simply fill the bag with crushed or whole shells, tie it securely, and hang it in your garden near plants that need calcium or are prone to pests. No digging required.


Tips for Best Results

  • Crush lightly: Large pieces work fine, but lightly crushed shells release nutrients faster.
  • Replace periodically: Over time, the shells break down, so refresh the bag every few months.
  • Combine methods: For extra protection, scatter some crushed shells around plant bases as well.
