Misting can temporarily increase humidity for tropical plants, but it is not a complete solution. Leaves may dry quickly, especially in centrally heated homes, so consistent humidity through a pebble tray or humidifier is often more effective.
Avoid over-misting, as wet leaves can encourage fungal diseases. Mist early in the day to allow leaves to dry before night.
Plants such as ferns or Calathea benefit from occasional misting, while succulents and cacti do not require it.
