Discover the benefits and methods of making eggshells as fertilizer or homemade compost for succulents or cacti.
What is the eggshell for in succulents?
When we explain how to make soil for succulents, we not only talk about a series of components that you can use, but we also mention some “ingredients” that you could add to your recipes, as well as the different benefits that each one of them provided.
One of the components or ingredients we are talking about is the eggshell. The eggshell is a waste that to a greater or lesser extent almost everyone has at home.
Eggshells can be used as a fertilizer or homemade compost for succulents and cacti. They provide calcium, phosphorus, potassium, iron and magnesium. These are very important nutrients to promote its development and growth.
How to use the eggshells as fertilizer or compost?
1. As part of the succulent soil mix
You can use the eggshells as a component of the substrate. First of all, you must rinse the shells well to remove the remains of the yolk or egg white, as they can cause a bad smell and the appearance of any disease.
Once the shells are rinsed, you must let them dry. Leave them in a cool, ventilated place or put them in the sun to speed up the drying process. Then you must grind them. For this you can help yourself with a mortar, food processor, or simply crush them with some object used for crushing.
Once crushed you can apply them directly in the soil mix.
In case you want to add them in the container where the succulent is already planted, it is advisable to water immediately after pouring the powder to ensure that the substrate absorbs it well.
Eggshells take months to decompose within the substrate so it is not recommended to add them more than once a year.
As we recommend in the storage of substrate, you can store the excess in a closed and dry container to use in future occasions.
2. By making tea or infusion out of eggshells
Another way that you can use eggshells to add nutrients to succulents is by making a tea or infusion. Applied in this way, it is a fertilizer for succulents and cacti. (Read also our article on making banana peel tea fertilizer)
To make the tea, you must, again, rinse the shells to remove excess white or dirt that they may have. Break them a little with your hands or, as in the previous method, with the help of a mortar or food processor.
Then, put them in boiling water. The recommended ratio is 2 generous tablespoons of crushed shells for every 4 liters of water.
Put the mixture to boil for approximately 10 minutes and then will let it rest for about 24 hours. Then filter the mixture with the help of a strainer or cloth.
Use the liquid from the infusion to water your succulents and you will be providing them with all the nutrients that the eggshell contains. Remember that succulents should not be fertilized frequently. We recommend that you carry out the fertilization process once a year, preferably at the beginning of the active growth season or during flowering.
