How much humidity does assai palm need?
What actually works
What works, in order: a small humidifier nearby (by far the most effective), grouping plants together so they share transpired moisture, or standing the pot on a tray of damp pebbles (the pot base must sit above the water, not in it). A bathroom or kitchen with a window often suits assai palm better than a living room.

Relying on misting. It lifts humidity for a few minutes at most, then it is gone — it cannot hold assai palm at 70-90%, and wet leaves overnight encourage fungal problems. A humidifier or grouping does what misting only appears to do.
