What causes crispy leaves on houseplants?
It depends on the plant and how it is kept, so check the plant pages below. For Philodendron, the records explain it like this: Crispy brown leaf edges on Philodendron stem from chronic underwatering or low humidity (<40% RH), causing guard cell closure and cessation of photosynthesis. Aroids evolved in tropical understories with 60-80% humidity; indoor heating reduces ambient moisture, forcing plants to sacrifice peripheral leaf tissue to preserve vascular integrity and root system.
Common first steps
- Increase humidity immediately: install humidifier, use pebble trays, or group plants to create microclimate
- Water thoroughly when top 2 inches of soil are dry; ensure water exits drainage holes
- Trim severely crispy edges with sterilized scissors for aesthetics (optional; not required for health)
