While an average person might just think of eggs for cooking, gardeners, especially those who are obsessed with gardening, think of eggshells as a wonderful resource.

Here are five ways to use eggshells in your garden.

1. Crush eggshells and add them to the bottom of planting holes, especially for crops like tomatoes, peppers, and eggplants. These plants are prone to blossom end rot, caused by a lack of calcium. By adding eggshells, your garden will have a steady source of calcium, and the soil will also be nourished as the shells break down.

2. Use eggshells as pots for starting seedlings. Plant the seedling with the eggshell “pot” directly into the garden.

3. Crush eggshells to keep slugs, snails, and cutworms away. These pests can be a real headache for gardeners, particularly cutworms, which can sever seedlings’ stems at the soil level. Since these pests dislike anything sharp, crushed eggshells on the soil’s surface might help deter them.

4. Add eggshells to your compost pile. If you’re not using them for tomatoes or pest control, adding eggshells to your compost pile is an excellent way to add calcium to your finished compost.

5. Crush up eggshells and place them in a dish near bird feeders if you’re feeding birds in your yard. Female birds, particularly those who are getting ready to lay eggs or have recently laid them, require more calcium.

Regardless of how you use them, ensure that you rinse the eggshells thoroughly before using them in your garden.

1. Why should I use eggshells in my garden?

Eggshells are an excellent source of calcium, which is essential for the growth and health of plants. Additionally, eggshells can be used to deter pests, such as slugs and snails, as the sharp edges of crushed eggshells can cut their soft bodies and prevent them from crawling over plants.

2. How do I prepare eggshells for use in my garden?

To prepare eggshells for use in your garden, rinse them thoroughly to remove any egg residue and allow them to dry completely. Once dry, crush the eggshells into small pieces using a mortar and pestle or a food processor.

3. Can I use eggshells for all types of plants?

Eggshells can be used for most types of plants, but they are particularly beneficial for plants that require a lot of calcium, such as tomatoes and peppers.

4. How do I use eggshells to deter pests?

To use eggshells to deter pests, sprinkle crushed eggshells around the base of your plants. The sharp edges will discourage pests from crawling over the shells and onto your plants.

5. Can I use eggshells as a natural fertilizer?

Yes, you can use eggshells as a natural fertilizer. Crushed eggshells can be added to your compost pile or directly to the soil around your plants. As the shells break down, they release calcium and other nutrients into the soil.

6. Are there any plants that should not be given eggshells?

Plants that prefer acidic soil, such as blueberries and azaleas, may not benefit from the addition of eggshells as they can raise the pH level of the soil. Additionally, eggshells should not be used on plants that are sensitive to calcium, such as potatoes and sweet potatoes.

7. Can I use eggshells in indoor plants?

Yes, you can use eggshells in indoor plants. Crushed eggshells can be added to the soil in your indoor plant pots to provide calcium and other nutrients. Additionally, eggshells can help to keep pests, such as fungus gnats, away from your indoor plants.
