It’s good to know that eggshells contain 93% calcium and 1% nitrogen, making them a vital addition to the soil.

In addition, eggshells can also help maintain a balanced soil pH. It’s important to keep in mind that eggshells must be dried and cleaned before using them as fertilizer to prevent the growth of bacteria or fungi.

However, be careful if you add them in large quantities; they can change the soil’s pH, making it more basic.

How to Treat Eggshells

To properly use eggshells, once you’ve separated them from their contents, wash them and let them dry for at least 24 hours.

Then, place them in small bags and crush them, obtaining small pieces, which you can use to scatter on the soil, in flowerbeds, in pots, or in the garden itself, between plants, near the stem.

By doing this, you’ll be providing a lot of energy to the plants, as eggshells contain a high percentage of calcium carbonate, the same calcium our bones need to grow strong, so you get an idea of how important it is.

You can also apply the ground eggshell to your own compost or substrate, or to your homemade compost.

There are many options available to obtain extra energy for plants to grow healthy and strong.

Many people boil the broken eggshells and then use them as irrigation water for plants.
