1. Choosing the Right Onion
Not all onions are the same, and for best results, you should use:
-
- Fresh yellow or red onions, as they have the highest sulfur content.
- Avoid onions that are too old or sprouting, as they may have lost some of their beneficial compounds.
2. Preparing the Onion Slice
-
- Take one thin slice of onion (approximately 1-2 mm thick) per week.
- Ensure the slice is fresh each time you use it.
3. Applying the Onion to the Orchid
There are two main ways to apply the onion: soaking in water for spraying or direct application.
Method 1: Onion Water Spray
This method ensures the nutrients from the onion are easily absorbed by the orchid leaves and roots.
Steps:
-
- Place one thin slice of onion into 500 ml of water and let it sit for 1 hour.
- Strain the water to remove any solid particles.
- Pour the onion water into a spray bottle.
- Lightly mist the leaves and aerial roots of the orchid once a week.
✅ Benefits: Absorbs nutrients quickly and strengthens the plant’s immune system.
Method 2: Direct Application on the Orchid
This method works best for promoting flower spikes.
Steps:
-
- Place the onion slice directly on the orchid’s root base or near the dormant flower spike.
- Leave it for 1-2 hours, then remove it.
- Repeat once per week for maximum effectiveness.
✅ Benefits: Directly delivers growth-boosting compounds to the orchid.
4. Combining Onion Treatment with Proper Orchid Care
For the best results, combine the onion method with proper orchid care:
-
- Light: Place the orchid in bright, indirect sunlight to promote healthy blooming.
- Watering: Water the orchid only when the roots turn silvery-gray to prevent root rot.
- Humidity: Maintain humidity levels between 50-70% for optimal growth.
- Air Circulation: Ensure good air circulation to prevent fungal infections.
- Potting Medium: Use a mix of pine bark, coconut husk, and sphagnum moss to provide excellent drainage.
