Can orchids be planted with eggshells?

Actually, eggshells can be used as a high-quality phosphorus fertilizer material for growing orchids, but they need to be treated beforehand before mixing them into the substrate as a base fertilizer or applying them as a top-dressing. If raw eggshells are placed in the orchid pot without treatment, they can easily attract pests like "small black flies," which not only affects environmental hygiene but can also lead to orchid diseases and pests.

Can eggshells be used to grow orchids?

Although eggshells may seem insignificant, they contain a wealth of nutrients. In addition to phosphorus, potassium, and calcium, they also contain many trace elements.

In terms of the benefits of using eggshells, we can simply process them to use for gardening, and the results are no worse than commercial nutrient-rich soil. They are especially breathable, allowing orchid roots to absorb nutrients well without rotting.

The nutrients in eggshells are abundant, and adding a handful once a month is usually sufficient. This not only improves soil breathability but also supplements nutrients, achieving a win-win situation. Those who grow orchids at home can try this method, which is simple and effective.

How to use eggshells as fertilizer for orchids

I. Making Eggshell Fertilizer

Eggshells are mainly composed of crystalline calcium and a protein-fiber matrix, rich in organic phosphorus, calcium, iron, and other nutrients.

Eggshells can be collected, dried in the sun, crushed, and then ground into a powder in a mortar. Using this as a base fertilizer for orchids is much better than placing eggshells directly into the orchid pot.

[Usage]

When repotting orchids in spring, take a small amount of eggshell powder and mix it with peat soil and other soft substrates.

You can also, about 2-3 weeks before the orchid forms buds to blooming, dig a small trench about 3 centimeters deep along the edge of the pot with your hand and bury the eggshell powder in the substrate and cover it well.

Then, through watering, the calcium, iron, and phosphorus in the eggshell powder will slowly leach out and be absorbed by the orchid roots, making the orchids vibrant and lush.

II. Mixing into Substrate

You can also clean the raw eggshells, fry them in a iron pot, or dry them in the sun, and then crush them into granules or powder with a mortar or small stone mill. Then, mix a small amount of crushed eggshells into peat soil or other soft substrates.

Its main functions are: on the one hand, eggshell powder can provide orchids with calcium, phosphorus, iron, magnesium, and other trace elements; on the other hand, crushed eggshells can help loosen and aerate the soil.

Crushed eggshells in granular form, when mixed into the soil, can help with aeration and also leach out phosphorus, calcium, and iron trace elements.

In summary, using eggshells to grow orchids mainly utilizes the trace elements in the eggshells, such as phosphorus, calcium, iron, and magnesium. However, it is necessary to preprocess the eggshells physically.

Orchid enthusiasts should be reminded that it is not advisable to place eggshells directly into the orchid pot to avoid attracting pests like "small black flies," which is very harmful to the growth of orchids and the maintenance of environmental hygiene.

The above[] provides a comprehensive introduction to whether eggshells can be used in orchid planting, hoping to bring some plant-related knowledge to greenery enthusiasts.
