Black leg is a serious disease that can affect seedlings.
The main symptom of the disease is blackening of the root collar.
This situation usually leads to the death of the young plant.

How can we prevent the occurrence of such a dangerous disease?
It turns out that there is a very effective preventative measure. And, oddly enough, we are not talking about some chemical preparation, but about a completely natural powder.
Super remedy against black leg
One of the “enemies” of the disease is… the common eggshell.
Before using the hard shell of eggs as a means of protecting seedlings, this “waste” must be turned into powder.
It is done very simply. First, you need to put the shell in the oven for a few minutes. It is important to ensure that the mass dries out a little: in this form, it will be easier to crush.
Once the “waste” has reached the required state, it must be ground using a coffee grinder.
The resulting powder should be poured into containers with seedlings. As a result, the risk of black leg will be minimized.
