Why Humidity Matters (and What to Do About It)
Most homes are too dry for tropical plants. Understanding why humidity matters and the three things that actually help.
Most popular houseplants evolved in tropical and subtropical forests where humidity regularly sits above 60%. The average heated home sits around 30-40% — drier than the Sahara. This gap is why brown leaf tips and crispy edges are so common.
Key Points
What to Do
Notice which plants have brown or crispy leaf tips — those are the ones that need more humidity
Group humidity-loving plants together so they create a shared microclimate
Fill a shallow tray with pebbles and water, placing the pot on top (water should not touch the pot base)
If you have several tropical plants in one room, consider a small humidifier set to 50-60%
Keep plants away from heating vents and radiators, which create localized dry zones
