Households across Britain are being urged to save their eggshells this January instead of throwing them away, as a gardening expert claims the breakfast scraps can revolutionise gardens during the winter months.
Gardening specialist Ish, who shares advice on TikTok as gardening.with.ish, has outlined several benefits of using eggshells in the garden. In a recent video, he explained that the crisp, sharp edges of crushed shells act as a natural deterrent for slugs, which avoid crawling over them.
Ish also highlighted that eggshells can be used as a slow-release fertiliser. Rich in calcium, they promote root growth and nutrient transfer. He recommends crushing them into a fine powder using a bag or blender, then mixing with compost or placing at the base of plants. The shells break down slowly, providing a steady nutrient supply.
Additionally, eggshells can be added to compost heaps to accelerate decomposition due to their calcium content. They help prevent blossom end rot in tomatoes, peppers, and squash, and can balance soil pH while introducing essential minerals like phosphorus and magnesium. Eggshells can also serve as biodegradable pots for seed germination.
The gardening expert advises applying crushed shells directly to soil or watering them in. While whole eggs can be buried, this may attract pests unless buried deep enough. The technique is simple and cost-effective, priming gardens for spring growth.
