Getting Yellow Bells (Tecoma stans) to Bloom in Texas

Yellow bells (Tecoma stans) are tough, drought-tolerant shrubs that bloom heavily with minimal care. If yours produced lush growth but few flowers in year two, the cause is usually excess nitrogen.

Common Bloom-Blocking Mistakes

• Over-fertilizing: High-nitrogen lawn fertilizer leaching into beds promotes foliage at expense of flowers.
• Over-watering: Established plants need only monthly deep soaking in summer.
• Pruning at wrong time: Hard winter pruning delays bloom; tip-prune only after spring flush.

Remedies

1. Stop all fertilizer—especially lawn products near root zone.
2. Water deeply once every 3–4 weeks during dry spells.
3. Lightly shear after first spring bloom to shape; avoid heavy cuts.
4. Ensure 6+ hours direct sun; thin overhead branches if needed.

Tecoma blooms on new wood. With reduced nitrogen and proper moisture, flower buds will form within weeks. Expect a massive show by midsummer.
