This article reveals effective natural fertilizers for accelerating orchid blooming at home, based on tips from Romain Le Tallec, a florist in Lyon.

Banana Peel for Orchid Bloom:

Banana peel, rich in vitamins B6 and C, and minerals like potassium and magnesium, is an excellent natural fertilizer. Soak a washed and cut banana peel in 2 liters of water for 48 hours, then strain. The nutrient-rich water can be used to water orchids.

Egg Shells:

Eggshells, high in calcium and potassium, can be crushed finely and sprinkled on orchid bark. The soil absorbs these essential nutrients, boosting flowering.

Ash as Fertilizer:

Fireplace ash, loaded with calcium, potassium, phosphorus, and trace elements, can also fertilize orchids. Add it to the orchid’s soil post-watering. Ash enhances flowering and helps control insects, but lacks nitrogen and phosphorus. Use gloves due to its caustic nature.

Banana Tea and Powder:

Banana peels can be dried in the sun or oven and then blended into a powder. Use a teaspoon of this in 200 ml of hot water to make banana tea. Once cooled, it can be used on orchids. Alternatively, the dry banana powder itself can be a direct fertilizer.

Vegetable Cooking Water:

The nutrient-rich water from cooking vegetables (excluding salted water) is an excellent, unexpected fertilizer for orchids.

Usage and Timing:

Use these natural fertilizers cautiously. Overuse can harm orchids. In winter, fertilize once a month, increasing frequency as new shoots develop.

Troubleshooting Non-Blooming Orchids:

If orchids develop leaves but no flowers, it might be due to inadequate light or humidity. Orchids need light but not direct sun, and should be kept in a warm, humid spot away from drafts to encourage blooming.
