Eggshells as a fertilizer have both pros and cons.
On the one hand, this “waste” is beneficial to the garden and vegetable garden, as it replenishes the calcium deficiency and also makes the soil looser.
On the other hand, the shell can cause alkalization of the soil and the appearance of dangerous diseases and pests.
However, if you prepare the material correctly (heat-treat and grind it) and do not overdo it, the results will only be positive.
In addition, it is important to remember the following: eggshells are not suitable for all garden and vegetable crops.
But rest assured: the following plants will “react” positively to this fertilizer.
Cabbage
Hard egg shells dropped into holes when transplanting cabbage seedlings will have a positive effect on the garden crop.
In addition, it is worth scattering eggshells around the plant: this will create a barrier for gastropods.
Potato
Covering the spaces between rows with shells is a guarantee of getting large and appetizing potatoes.
Plum
Adding hard eggshells to the roots of garden crops helps to increase fertility.
In addition, the fruits collected as a result will have a very bright and pleasant taste.
But be careful: you can't "treat" the plum with eggshells too often. One procedure every 2-3 years is quite enough.
Tomatoes
Eggshells are a source of calcium. And this microelement is very necessary for tomato bushes.
