Eggshells have long been touted as a natural way to add calcium to the soil, deter pests, and improve drainage in the garden. Many gardeners crush eggshells and sprinkle them around their plants, believing that they are providing much-needed nutrients and protection. While these benefits are real, it’s important to understand that not all plants respond well to eggshells and their presence in the soil.

Plants That Don’t Like Eggshells

While eggshells are generally beneficial, there are some plants that don’t like eggshells and may suffer negative effects when they come into contact with them. These plants include:

Tomato Fruite








Azaleas Flower


    These plants are known to be sensitive to the alkaline properties of eggshells, which can disrupt the pH levels of the soil and hinder their growth. If you are growing any of these plants, it’s best to avoid using eggshells in your garden to prevent any potential issues.

    How Eggshells Affect Acid-Loving Plants

    When it comes to plants that thrive in acidic soil, such as blueberries and azaleas, the alkaline nature of eggshells can be particularly problematic. These plants require a lower pH level in the soil to absorb nutrients effectively, and the presence of eggshells can raise the pH and make it difficult for them to thrive. If you have acid-loving plants in your garden, it’s essential to be mindful of how you use eggshells and consider alternative methods for providing nutrients and pest control.

    Alternatives to Eggshells for Pest Control

    If you’re concerned about pests in your garden but want to avoid using eggshells around sensitive plants, there are alternative methods for pest control that can be just as effective. For example, diatomaceous earth, neem oil, and companion planting are all natural and safe ways to deter pests without risking harm to your plants. By exploring these options, you can protect your garden without compromising the wellbeing of your plants.

    Benefits of Eggshells for Other Plants

    While some plants may not like eggshells, it’s important to note that many others benefit from their presence in the soil. Plants such as roses, cucumbers, and squash can all benefit from the calcium and nutrients that eggshells provide. These plants generally prefer a more alkaline soil, making them well-suited to the properties of eggshells. By understanding the needs of your specific plants, you can make informed decisions about when and where to use eggshells in your garden.

    Proper Application of Eggshells in the Garden

    For plants that benefit from the presence of eggshells, it’s essential to apply them correctly to ensure that they are effective without causing harm. Crushing eggshells into small pieces and adding them to the soil can help to release calcium gradually and improve its structure over time. Additionally, layering eggshells around the base of plants can deter pests and provide a natural barrier against slugs and snails. By understanding the specific needs of your plants, you can use eggshells in a way that is beneficial and safe.

    Conclusion: Finding a Balance in the Garden

    As with any aspect of gardening, it’s important to find a balance and consider the individual needs of your plants. While eggshells can be a valuable resource for providing nutrients and deterring pests, it’s crucial to be mindful of which plants may not like them and adjust your approach accordingly. By understanding the specific requirements of your garden and the plants you are growing, you can make informed decisions about how to best utilize eggshells and promote a healthy and thriving garden.
