Using eggshells as flower fertilizer works even better than commercial fertilizer

Autumn is the peak growing season for plants, so they need plenty of nutrients. If you use store-bought fertilizer, it will cost you a lot of money. Better to use the most common household waste - eggshells - and then add a few little extras, and use them to grow flowers. That way you can give your plants plenty of nutrients, and you never have to spend money on flower fertilizer again!
Using eggshells directly
First wash the eggshells clean, then put them out in the sun to bake. Once they are dried, crush the eggshells directly into a powder, then spread it evenly over the surface of the soil. When you water, the nutrients in the eggshells will seep into the soil, supplying the plants with calcium and making them grow stronger and more robust.
Eggshells + fruit peel
First wash and dry the eggshells, then crush them and put them in a clean plastic bottle. Add an appropriate amount of fruit peel, then leave the bottle out in the sun to bake. Fermentation is basically complete in about a month. Then mix the liquid with clean water at a ratio of 1:100, stir well, and water directly. This supplies the plants with plenty of nitrogen, phosphorus, calcium and other elements, and makes the root system grow stronger and stronger.
Eggshells + vinegar
Wash the eggshells clean, then crush them and put them in a clean container. Add an appropriate amount of vinegar, stir well and let it soak for a while. After soaking, take the eggshells out, then mix the liquid with clean water at a ratio of 1:100, stir well, and pour it directly onto acid-loving flowering plants. This makes the leaves deep green and also prevents chlorosis, so you never have to worry about yellowing leaves again.
