Crushed eggshells can serve as a natural deterrent for pests like slugs and snails. The sharp edges of the crushed shells can deter these soft-bodied pests from attacking your plants, providing a chemical-free method of protection.
3. Compost Booster

When added to compost, eggshells provide an additional source of calcium, which is necessary for microbial activity. This in turn helps to speed up the composting process and enhance the quality of the compost produced.
4. Soil pH Balancer
The calcium carbonate in eggshells can help to neutralize acidic soil, making it more alkaline. This is especially beneficial for plants that prefer a balanced or slightly alkaline pH level.
5. Waste Reduction
By reusing eggshells in your garden, you are reducing kitchen waste that would otherwise end up in a landfill. This small step contributes to a more sustainable lifestyle and eco-friendly gardening practices.
6. Bird Attractant

Birds are attracted to eggshells for their calcium content, especially during nesting season. Having eggshells in your garden can attract beneficial birds that help with pest control.
7. Visual Indicator
A mesh bag of eggshells can serve as a visual reminder to regularly check and maintain your garden, promoting a more attentive gardening routine.
8. Microbial Activity Boost
Eggshells can help boost microbial activity in the soil, enhancing the breakdown of organic matter and improving soil health.

Implementing these practices is easy and requires minimal effort. Simply collect your eggshells, allow them to dry, crush them slightly, and place them in a mesh bag. Hang the bag in a strategic location in your garden to reap the benefits. Your plants and the environment will thank you!
