Just add a small amount to your plants and they will bloom in just a week

There are three methods to integrate them into the life of the plant  .  The first method, the most common, is to take dried eggshells, crush them until they break into very small pieces and sprinkle them on the soil. For an even more potent result, you can also mix them with coffee grounds.

Finally, there is another way to take advantage of the properties of eggshells: After finely chopping the shells, you can put them in half a glass of vinegar with a good portion of warm water. With this fantastic trick, you will see how your plant thrives and grows  healthy  in no time, the result will leave you speechless.
