Curling Leaves on anthurium
What's Happening
Leaf curling in anthuriums indicates water stress - either too much or too little. Underwatering causes leaves to curl inward to reduce surface area and conserve moisture. Overwatering/root rot prevents water uptake, causing similar curling despite wet soil. Other causes include low humidity, heat stress, or pest damage affecting water transport.
How to Fix It
- 1
Check soil moisture immediately: insert finger 2-3 inches deep
- 2
If soil is dry: water thoroughly until water drains from bottom
- 3
If soil is wet and plant is curling: check for root rot (unpot and inspect)
- 4
For root rot cases: trim rot, repot in fresh mix, water sparingly
- 5
Increase humidity to 60%+ to reduce water loss from leaves
- 6
Move away from heat sources (radiators, heating vents)
- 7
Check for pests on stems and leaf undersides that might affect vascular system
How to Prevent It
Maintain consistent watering schedule based on soil dryness, not calendar; use well-draining mix to prevent both drought and waterlogging; keep humidity 60-80%; avoid temperature extremes; monitor for pests regularly; use clear pots to visually assess moisture and root health
