Yes, eggshells can be beneficial for grass, primarily due to their calcium content.
How Eggshells Help Your Grass
Eggshells are not a direct fertilizer for grass but instead act as a soil amendment. When crushed, they release calcium into the soil, which benefits plant growth. While grass does not require a high amount of calcium, it helps improve soil structure and can help other plants in the lawn that might be calcium-loving. Here's how:
- Calcium Source: According to the reference, “Crushed eggshells can add valuable nutrients back into the soil with the high-level of calcium being very beneficial to plants.” This calcium is essential for strong plant cell walls.
- Soil Structure: Calcium can help loosen compacted soils, allowing better root growth for grass.
- Natural and Organic: Eggshells provide an organic way to improve soil without using chemicals.
How to Use Eggshells on Grass
- Collect: Save your eggshells after cooking or baking.
- Clean: Rinse the shells to remove any remaining egg whites.
- Dry: Let the shells dry completely.
- Crush: Crush them into small pieces, or even a fine powder, using a blender or by hand.
- Apply: Sprinkle the crushed eggshells on your lawn or work them into the soil.

Important Note
While eggshells are beneficial, they decompose slowly. This means that they provide a slow release of nutrients. This slow release is important because it won't provide a surge of nutrients to the soil. Remember that eggshells aren't a replacement for fertilizers if your grass requires more nitrogen, phosphorus, or potassium.
