Make a calcium-rich fertilizer

If you are looking to make calcium for plants at home, we encourage you to use eggshell to achieve it in the simplest and most economical way possible. For this you only need, as we have explained before, crush the eggshell and place them on the substrate that you use as soil for your plant.

Calcium for plants is one of the richest minerals to improve their development. For this reason, as the release of calcium in the soil is quite slow, there are many who choose to add eggshells to help the crops prevent rot. If you have roses in your home or garden, we also advise you to use the eggshell to improve the soil and promote its flowering.

Reduce the acidity of the soil

Many plants need a specific type of soil for their growth. Therefore, a home method to control the acidity of the soil where your plants are is to add ground eggshell to the plants . To achieve this you need to add the well-ground eggshell for a long period of time to achieve good results. The irrigation water will facilitate the release of the components of the shells in the soil.

Make homemade compost

If you are one of those who are encouraged to make your own organic compost or compost, we encourage you to add remains of eggshell so that it is much richer and more complete for your plants.

How to Prepare Eggshell Calcium for Plants

Although we have already discussed how to prepare the eggshell to improve the state and growth of your plants, we want to show you other ways to prepare them beyond crushing them to add them as organic fertilizer or as a repellent. Take note of these tips on how to make calcium from egg shells for plants :

  • You can use the crushed eggshell to make an infusion of these, using the shell of 6 eggs and bringing them to a boil in 3 liters of water. This eggshell water for plants is a very simple way to add more calcium and other beneficial minerals such as magnesium or phosphorus to your plants through irrigation doses.
  • Another way to prepare it is by creating eggshell flour. This takes a series of steps that are a little more precise, but that assure you almost immediate results in the well-being of your plants. All you have to do is make sure you let them dry in the shade to prevent them from losing the nitrogen they have. You will need quite a few of them, at least a dozen shells, to produce the flour. When they are dry, place them in a bag and crush them with the help of a mortar or a stone until they are a very fine powder and reserve them in a container with a lid until you use it. Remember that for some of the uses explained above, small pieces of shells are used, but that in the case of flour we are talking about using the powder of these shells, so they must be crushed to the maximum. Using eggshell flour is very simple: You only need to add one or several dessert tablespoons to your pot depending on its size for about 40 days. In this way, they will receive the calcium intake they need.
