Mass Cane (Dracaena massangeana) Brown Spots: Fertilizer Burn on Drought-Stressed Plant

A Dracaena massangeana left dry 3 weeks, then fertilized immediately, shows brown spots from fertilizer burn on desiccated roots.

What Happened

• 3 weeks no water = severe drought stress.
• Fertilizer on dry roots = chemical burn → root death → leaf browning.
• Stem wilt = root system collapse.

Salvage Attempt

1. Set pot in tub; slowly run water through to flush fertilizer.
2. Do not fertilize again until healthy new growth.
3. Water only when soil dry (skewer test).
4. Bright indirect light (north window okay).

Prevention

• Arrange plant-sitting for absences >1 week.
• Water first, wait a week, then fertilize after drought.
• Use bamboo skewer to monitor moisture.

May recover if some fine roots survive. Lesson: never fertilize a bone-dry plant.
