Eggshells are considered to be an effective and absolutely safe garden remedy.
It would seem, what harm can this natural fertilizer cause to plants and soil?
But there are several dangers that many gardeners and vegetable growers do not take into account.
An expert of the online publication "BelNovosti", agronomist and landscape designer Anastasia Kovrizhnykh spoke about the hidden dangers of the product.
The Hidden Dangers of Eggshells
Changing the pH of the soil
Many gardeners forget that too frequent application of hard egg shells can cause the soil to become highly alkaline.
This type of soil is not suitable for many plants.
Ailments
Eggshells can also be a source of pathogens.
Introducing contaminated mass into the soil may result in the death of flora.
The emergence of pests
Eggshells that are not properly prepared for placement in the soil can attract dangerous insects to the area.
What to do with eggshells before adding
First, the collected mass must be subjected to heat treatment. The procedure is necessary to rid the shell of pathogens.
Secondly, the hard shell of the eggs should be finely ground. It is advisable to turn it into powder. This way the product will quickly decompose and will not attract ants and other pests.
And one more important recommendation: add crushed eggshells moderately. Excess of the product will negatively affect both the soil and the plants.
