Wash the egg shell with clear water, dry it and grind it into powder.
Evenly sprinkle a layer of egg shell powder on the surface of the basin soil.
After pouring water, gently pat the soil to make the eggshell powder fully contact with the soil.
Under normal circumstances, egg shell powder can be applied once a month. If you want to increase the effect, you can appropriately increase the number of fertilization.
It should be noted that egg shell powder can not be directly put into the soil, otherwise it will easily form lumps, which will affect the respiration and growth of plant roots. In addition, eggshell powder should not be used excessively, otherwise the soil will be too acidic or too alkaline, which will have a negative impact on plants.
