Why are Eggshells Good for Plants?

As gardeners, we are always looking for ways to improve the health and productivity of our plants. One tool in our arsenal that we might not always think about is something as simple as eggshells. Yes, those hard, outer casings of eggs that we typically discard can actually be a great source of nutrients and can benefit our plants in a number of ways. In this article, we will explore why eggshells are good for plants and how to use them effectively.

Eggshells Provide Calcium

Eggshells are composed primarily of calcium carbonate, which is a valuable mineral for plant growth. Calcium is essential for plant development, helping to form strong cell walls and aiding in the proper absorption of other nutrients. Without enough calcium, plants may become stunted, and their leaves may yellow or curl. By incorporating crushed eggshells into the soil, gardeners can provide their plants with a slow-release source of calcium that will benefit them throughout the growing season.

Eggshells Improve Soil Structure

Eggshells can also improve the physical characteristics of soil. When eggshells are crushed into small pieces, they can work their way into the soil and help to keep it loose and friable. This, in turn, allows for better drainage and aeration, which are important for healthy root growth. Additionally, the calcium that eggshells provide can help to neutralize acidic soils, making them more hospitable to a wider range of plants.

Eggshells Repel Pests

The sharp edges of crushed eggshells can help to deter certain pests from attacking plants. Slugs, snails, and other soft-bodied insects may avoid crossing a barrier of eggshells, reducing the likelihood of damage to leaves and fruit. However, it should be noted that eggshells alone are not a foolproof method of pest control, and should be used in conjunction with other measures.

How to Use Eggshells in the Garden

Now that we know the benefits of eggshells for plants, how can we use them effectively in our gardens? There are a few different ways to incorporate eggshells into your garden soil:

Crush eggshells into small pieces and mix them into the soil before planting.

Place crushed eggshells at the bottom of planting holes to provide a slow-release source of calcium.

Spread crushed eggshells around the base of plants to repel pests.

It's important to note that eggshells should be cleaned and dried before use to avoid introducing any unwanted bacteria or pathogens into the soil.

A Final Word

Overall, eggshells can be an excellent addition to any gardener's toolkit. They provide calcium for plant development, improve soil structure, and can even help to repel pests. By incorporating crushed eggshells into your garden beds, you can give your plants a natural boost and help them thrive.
