In winter, many orchids stop blooming, the leaves turn pale, and the roots wither, despite watering. Flower growers think that they have “over-watered” or “under-watered”, but in fact the plant lacks nitrogen and organic matter, which are quickly depleted in the bark – the main substrate for orchids.
But instead of special fertilizers, you can use what remains after your morning coffee. We are talking about coffee grounds. It slightly acidifies the soil and provides beneficial substances that help roots grow, protect against diseases, and even make them bloom in winter.
How to use:
- Take the grounds from 2-3 cups of coffee, squeeze well and dry for 1 day on a radiator or at room temperature.
- Grind to fine crumbs.
- Gently mix 1 teaspoon into the top layer of substrate.
- Repeat every 6-8 weeks. More often it is impossible, so as not to acidify the substrate.
After just 2-3 weeks you will notice: the leaves become lush green, the roots are silver-green and elastic, and new buds appear on the flower stalks even in winter.
Question and answer:
How much coffee grounds can you put in an orchid pot?
No more than 1 teaspoon per adult plant. Excess will cause acidification and rotting of the roots.
Can I use instant coffee grounds?
No. It contains almost no nutrients, but a lot of sugar and flavorings. Use only natural ground coffee grounds.
Why doesn't the orchid bloom in winter?
Due to substrate depletion and lack of microelements. The bark contains almost no nutrients, and without feeding, the plant goes into survival mode.
