Can You Put Eggshells on Top of Soil?
Yes, you can put eggshells on top of soil, but the method and benefits depend on your goals.
Crushed eggshells, when added to soil, provide several benefits:
- Calcium Source: Eggshells are primarily calcium carbonate, offering a slow-release source of calcium for plants. This is beneficial for plants needing strong stems and fruit production (e.g. tomatoes). [Source: Quora, Reddit, Southern Living]
- Improved Soil Structure: Adding eggshells to the soil improves drainage and aeration, leading to healthier plants. [Source: getstronganimals.com]
- Pest Deterrent: Laying crushed eggshells on top of the soil can deter slugs and other crawling pests due to their sharp edges. [Source: Modern Milkman, Laying crushed eggshells...]
How to Use Eggshells in Your Garden:
- Crush the eggshells: Thoroughly crush or grind the dried eggshells for better incorporation into the soil.
- Composting (Recommended): Composting eggshells before adding them to the soil is beneficial. This allows for better decomposition and nutrient release. [Source: Nourish and Nestle]
- Incorporating into soil: Add crushed or composted eggshells to the soil during planting or as a top dressing.
Using Eggshells as a Mulch or Top Dressing
Placing crushed eggshells on the surface of the soil offers a different set of advantages:
- Slug and Pest Deterrent: This is the primary benefit, creating a physical barrier that deters slugs and snails from reaching plants. [Source: Modern Milkman, Laying crushed eggshells...]
Important Considerations:
- While eggshells are beneficial, they are not a quick fix. The release of nutrients is gradual. [Source: Reddit]
- Overuse of eggshells can slightly alter soil pH, so moderation is key. [Source: Reddit]
Conclusion
Eggshells offer various uses in gardening, both as a soil amendment and as a pest deterrent. Proper preparation and application are key for optimal results.
