The Scarlet Clock Vine (Thunbergia coccinea) is a beautiful, fast-growing climber with bright red-orange tubular flowers—perfect for pots if you give it support and warmth.
🌱 1. Choosing the Right Pot
- Use a large pot (at least 12–16 inches wide and deep).
- Ensure good drainage holes—this plant hates waterlogging.
- Add a trellis, bamboo sticks, or railing for climbing.
☀️ 2. Light Requirements
- Needs full sun to partial shade.
- In hot regions (like West Bengal), give:
- Morning sun ☀️
- Light afternoon shade 🌤️ (prevents leaf burn)
🌿 3. Soil Mix
Use a well-draining, rich mix:
- 40% garden soil
- 30% compost/vermicompost
- 20% coco peat
- 10% sand or perlite
👉 Slightly acidic to neutral soil works best.
💧 4. Watering
- Keep soil consistently moist, not soggy.
- Water when the top 1–2 inches dry out.
- Reduce watering in winter.
🌼 5. Fertilizing
- Feed every 2–3 weeks during growing season:
- Liquid compost tea OR
- Balanced fertilizer (like NPK 10-10-10)
- For more blooms, switch occasionally to a phosphorus-rich feed.
🌡️ 6. Temperature & Climate
- Thrives in warm, humid climates (ideal for your region 👍).
- Protect from:
- Cold below 10°C
- Strong dry winds
✂️ 7. Pruning & Training
