ok mariah, first let me welcome you to the garden helper's forum. we are a friendly bunch, and glad to have you.

second... about your fern. when a plant is brought in from outside, the leaves (especially those on a fern) tend to die off leaving new ones in their place. the reason for this seems to be the change in humidity and light intensity. cutting the brown ones off is the right thing to do. and rather than misting, you might want to set your plant on a pebble tray with water. just make sure the plant isn't actually sitting in the water. the evaporation of the water from the tray will give the plant more even and consistant humidity. hope this helps. let us know how you make out!
