Eggshells are a treasure for gardening enthusiasts. Find out why we put them in boiling water.
Many of us have the habit of discarding eggshells without thinking twice.
However, what many people don’t know is that this seemingly useless waste hides an incredible secret for taking care of your garden.
In this article, we’ll reveal a simple trick that can make a big difference in the health of your plants. Get ready to change your perception of eggshells!
The Nutritional Power of Eggs
Before we dive into the world of gardening, it is worth highlighting the importance of eggs in our diet.
Rich in proteins, vitamins B12 and K2, as well as essential minerals such as calcium, iron and phosphorus, eggs are a superfood that, when consumed in moderation, bring countless health benefits.
But when you finish preparing an omelet or a cake, what do you do with the shells? If the answer is “throw them away,” it’s time to rethink this practice.
Eggshell: A Treasure Hidden in the Trash
Eggshells are a treasure trove for gardening enthusiasts. They can be used in two main ways to benefit your plants:
- Balancing Soil pH : The calcium in eggshells helps neutralize soil acidity, creating a healthier environment for your plants. After washing and drying the eggshells, simply crush them into small pieces and sprinkle them directly on the soil. This simple gesture can strengthen the growth of your plants, making them more robust and long-lasting.
- Calcium-Enriched Water : For an extra boost of nutrients, try boiling eggshells and using the “enriched” water to water your plants. This simple technique provides a concentrated dose of calcium and other essential minerals, encouraging healthy growth of the vegetation in your garden or planters.

Practical Tips for Application
- Quantity : The amount of shells depends on the size of your garden or the number of pots you have. Even the shells of a few eggs can be enough for smaller plants.
- Preparation : Wash the peels well to remove any residue and let them dry completely before grinding or boiling them.
- Application : If you choose enriched water, boil the peels for a few minutes and wait for them to cool before watering the plants.
Conclusion
Eggshells are much more than just kitchen waste. They can be turned into a valuable resource for your garden, contributing to the healthy and vigorous growth of your plants.
So, next time you’re preparing a hearty breakfast, remember to save the peels and give them a new life in your garden. Your greenery will thank you!
