Yellow Bells (ทองอุไร) – Tropical Garden Care Guide

Scientific Name: Tecoma stans
Thai Name: ทองอุไร (Thong-urai)

Yellow Bells are vibrant, sun-loving tropical shrubs known for their bright yellow trumpet-shaped flowers. They thrive in warm climates and are relatively low-maintenance, making them a great addition to any garden.


1. Propagation

Yellow Bells can be propagated through seeds or stem cuttings.

A. Seed Propagation

  • Collect seeds from mature pods after flowering.
  • Soak seeds in warm water for 24 hours to improve germination.
  • Sow seeds in well-draining soil (a mix of potting soil and sand works well).
  • Keep moist and place in a warm, sunny spot.
  • Germination time: 2–4 weeks.

B. Stem Cutting Propagation

  • Take cuttings (6–8 inches long) from healthy, semi-hardwood stems.
  • Remove lower leaves and dip the cut end in rooting hormone (optional).
  • Plant in soil or a water medium (change water every few days if propagating in water).
  • Roots develop in 3–6 weeks; transplant once established.

2. Pruning

Pruning helps maintain shape, encourage bushier growth, and improve flowering.

When to Prune:

  • Best done after the main flowering season (late dry season or early rainy season in Thailand).
  • Light pruning can be done year-round to remove dead or weak branches.

How to Prune:

  • Remove dead/diseased branches first.
  • Trim back leggy stems to promote bushier growth.
  • Cut just above a leaf node to encourage new shoots.
  • Avoid heavy pruning during peak flowering to preserve blooms.

3. General Care Tips

  • Sunlight: Full sun (6+ hours daily) for best flowering.
  • Watering: Moderate; allow soil to dry slightly between waterings.
  • Soil: Well-draining, slightly acidic to neutral pH.
  • Fertilizer: Use a balanced fertilizer (10-10-10) every 2–3 months in growing season.
  • Pests/Diseases: Watch for aphids and fungal issues; treat with neem oil if needed.

Final Tip: Yellow Bells are drought-tolerant once established, making them perfect for tropical gardens. With proper pruning and care, they’ll reward you with year-round golden blooms!
