Brugmansia (Angel’s Trumpet) Blossoms Browning: Check Drainage, Feeding, and Pests

Sudden Bloom Failure on a Potted Brugmansia

A large brugmansia in a self‑watering pot on a sunny deck bloomed well, then all blossoms browned at tips. Regular water and fertilizer.

Troubleshooting Checklist

1. Self‑watering system: Brugmansias hate wet feet. Ensure the pot drains freely; the reservoir may be keeping soil soggy.
2. Feeding: They are heavy feeders. Use compost or fertilizer for flowering shrubs. Add 2 tsp Epsom salts per gallon water monthly to prevent chlorosis.
3. Spider mites: Check leaf undersides; wash off with water or insecticidal soap.
4. Flower parasites: Midges or moths lay eggs in buds; larvae destroy ovaries.
5. Extreme heat: Very high temps can cause bud abortion.

Key Takeaway

Start with drainage – the self‑watering pot is the prime suspect. Then adjust feeding and scout for pests.
