Monstera Deliciosa: humidity myths
Quick answer
1980s-1990s houseplant books recommended misting Monsteras daily for humidity. Research on Monstera deliciosa leaf surface properties (PMID 20709828, 26644508) shows epicuticular waxes form transpiration barriers. Misting provides only temporary humidity increase (15-30 minutes) and can promote bacterial/fungal growth on leaves without addressing root-zone humidity. CAM photosynthesis adaptation allows Monstera to tolerate lower humidity than tropical understory suggests.
Start here:
- 1. For humidity: Use pebble tray with water (pot sits on pebbles, not in water)
- 2. Group humidity-loving plants together to create microclimate
