What are the benefits of using eggshells in the garden?
Eggshells are a fantastic addition to the garden due to their rich calcium content. Calcium is essential for plant growth, particularly for the development of strong cell walls and overall plant structure. By adding crushed eggshells to your soil, you can help prevent issues like blossom end rot in tomatoes and peppers, which is often caused by calcium deficiency.
In addition to calcium, eggshells can aid in improving soil texture. As they break down, they enhance drainage and help maintain moisture levels, creating a healthier environment for plants. Furthermore, using eggshells can attract beneficial organisms such as earthworms, which contribute to soil health and promote nutrient cycling.
How should I prepare eggshells for garden use?
To prepare eggshells for your garden, first, thoroughly rinse them to remove any egg residue, which can attract pests. It’s essential to let them dry completely to avoid mold growth.
