Indoor Care and Pruning of Angel Trumpet (Brugmansia)

Indoor Challenges

• Prefers full sun; window light insufficient for thriving.
• Dry indoor heat harms them; they like damp conditions.
• Need fertile, organic-rich soil with high phosphorus, low nitrogen.
• Pot ≥12 inches diameter to avoid root-binding.
• Keep top 2 inches of soil moist; water more often in low humidity.

Pruning

• Prune at least every 4 months to stimulate bloom and branch growth.
• Remove discolored branches first.
• Prune up to 1/3 of plant uniformly; use clean, sterilized pruners (1 tbsp ammonia/gallon water).
