humidity stress on Philodendron
Quick answer
If your Philodendron has humidity stress, the most likely cause is: Philodendrons evolved in tropical rainforest environments with 60-80% humidity. Indoor conditions often fall below 40%, causing delayed or stuck leaf unfurling, brown crispy edges, and increased susceptibility to spider mites. New leaves especially require localized high humidity to unfurl properly.
Start here:
- 1. Direct humidifier output toward new leaf sheaths
- 2. Mist new growth area daily (avoid over-wetting established leaves)
