Bauhinia purpurea (Kanchan / Purple Orchid Tree) in a pot is possible both indoors and outdoors, but it grows best with good sunlight.
🌱 1. Choosing the Pot
- Use a large pot (at least 14–18 inches deep) because Kanchan develops a strong root system.
- Ensure the pot has good drainage holes to prevent root rot.
🌿 2. Best Soil Mix
Kanchan prefers well-drained, fertile soil.
Recommended mix:
- 40% garden soil
- 30% compost or vermicompost
- 20% river sand
- 10% cocopeat
This mix keeps the soil nutritious but well-drained.
☀️ 3. Light Requirements
- Outdoor: Full sunlight (6–8 hours daily) – best for flowering.
- Indoor: Place near a south-facing or very bright window.
- If indoors, move it outside occasionally for sunlight.
Without enough sun, flowering may reduce.
💧 4. Watering
- Water when the top 2–3 cm of soil becomes dry.
- Avoid overwatering; Kanchan tolerates slight dryness better than soggy soil.
Typical schedule:
- Summer: 2–3 times per week
- Winter: 1 time per week (depending on dryness)
🌿 5. Fertilizer
Feed every 20–30 days during the growing season.
Good options:
- Vermicompost
- Mustard cake liquid fertilizer
- Cow dung compost
This helps the plant produce more flowers.
✂️ 6. Pruning
- Prune lightly after flowering.
- Remove dead or weak branches to keep the plant compact for pot growth.
🌸 7. Flowering
- Usually blooms late winter to spring depending on climate.
- Flowers are purple orchid-like, which is why it’s called an orchid tree.
