Eggshells are a fantastic natural resource that can significantly benefit your outdoor plant box soil. Rich in calcium and other essential minerals, crushed eggshells help improve soil structure, promote healthy root development, and even deter pests like slugs and snails.

To use eggshells effectively, rinse and dry them thoroughly, then crush them into small pieces or powder. Mix the crushed shells into the top layer of your plant box soil or add them to your compost pile for gradual nutrient release. Over time, the eggshells break down, enriching the soil with calcium carbonate, which is vital for preventing blossom-end rot in plants like tomatoes and peppers.

Additionally, eggshells act as a natural pH balancer, making them especially useful for acidic soils. For best results, combine them with other organic matter like coffee grounds or banana peels to create a nutrient-dense growing environment.

By repurposing eggshells, you not only reduce kitchen waste but also provide your outdoor plants with a sustainable, chemical-free boost. Try this eco-friendly gardening hack and watch your plants thrive!
