Reviving a Dying Anthurium: Watering, Pests, and Root Health

Reader Question

My Anthurium from Bunnings initially thrived in a humid bathroom with monthly fertilizing and watering 2–3 times weekly in bright indirect light. Then all leaves browned and died, including flowers. Now only one ugly green/brown leaf remains. I also see little white bugs at the base. What happened?

Root Cause: Watering Issues

The primary problem is improper watering. Plants die from frequency errors — too often or too infrequent — not from volume per watering. The white bugs are likely fungus gnats or springtails, which thrive in constantly moist soil.

Correct Watering Method

1. Water thoroughly until excess drains out.
2. Lift the pot — feel its weight when fully watered.
3. Do not water again until the pot feels considerably lighter and the top soil is pale.
4. This may mean watering every 5–10 days, not on a fixed schedule.

Immediate Actions

• Remove all dead/brown foliage back to live tissue.
• Stop fertilizing until recovery.
• Send a clear photo of the white bugs for precise ID.
• Ensure the pot has drainage; empty saucers promptly.

Recovery is possible if roots aren't fully rotted. New growth will emerge from the crown if the root system survives.
