In autumn, many orchids freeze: the leaves turn pale, growth stops, and the peduncle never appears. Many people begin to water more often, put them under a lamp, or buy stimulants. But in reality the problem is different. The plant lacks calcium, which is needed for the formation of strong cells and the formation of buds.
But there is a source of calcium in every kitchen. We are talking about eggshells.
Orchids, especially phalaenopsis, respond very well to calcium: it helps the leaves become denser and richer in color, and also promotes the appearance of buds even in winter, when there is little light.
How to use:
- Collect shells from 3-4 eggs, rinse well and dry for 1-2 days.
- Grind in a coffee grinder or mortar until fine crumbs.
- Gently mix 1 teaspoon into the top layer of substrate.
- Repeat every 6-8 weeks, especially from October to February.
After 3-4 weeks, you will notice that the leaves have become more elastic and rich green in color. And after 1.5–2 months, many will have a new peduncle.
Question and answer:
Do I need to bake the shells before use?
It is not necessary, but it is advisable to rinse and dry well to remove any protein residue and avoid any odor or mold.
Is it possible to replace the shell with chalk or plaster?
No. Chalk and gypsum contain calcium carbonate, but can disrupt the pH of the substrate. The shell is softer and safer for epiphytic plants.
