Which flowers are suitable for using eggshells as fertilizer

Using eggshells as flower fertilizer is something every gardener knows. That is because eggshells contain many minerals and calcium, as well as trace amounts of phosphorus fertilizer. Burying eggshells in the soil can also make the soil loose and breathable, so it does not compact easily. That is why many people like to collect eggshells and turn them into flower fertilizer.

When making flower fertilizer from eggshells, be sure not to place the eggshells upside down directly in the flower pot, because then the liquid inside the eggshells will flow onto the surface of the pot. It easily ferments on the pot surface, gives off a strong odor, and also easily breeds pests. If there is a large amount, it can also easily burn the flowers.

When making fertilizer, we should wash the eggshells clean. Then sun them for a few days or roast them a little over a fire. After a few days of sunning, the eggshells crumble easily with a pinch of the hand.

Crushing them and mixing them into the soil lets the fertilizer slowly ferment so the plants can absorb it. It not only provides the plants with a lot of calcium and trace amounts of phosphorus, but can also play a role in aerating the soil.

Crush the eggshells and scatter them around the edge of the flower pot to prevent snails, slugs and other mollusks from damaging the plants, because the sharp edges of the eggshells will cut them, which can serve as a preventive measure

Flower fertilizer made from eggshells is suitable for most potted flowers. However, for plants with thicker roots such as clivia and orchids, it is best not to use it. That is because the edges of eggshells are rather sharp, and when mixed into the soil they easily cut their fleshy roots, causing root damage and the occurrence of hollow roots.
