Likely causes
Dry Soil
Most likelyHow to tell: The tips of the leaves turn crispy and brown while the rest of the plant looks thirsty.
What to do: Water the plant thoroughly until water runs out of the drainage holes. Maintain a consistent schedule so the soil stays evenly moist.
Low Humidity
PossibleHow to tell: The leaf tips brown slowly in a dry indoor environment.
What to do: Mist the plant occasionally or place it on a tray filled with pebbles and water. This increases the moisture around the foliage.

When to worry
Brown tips are rarely fatal but indicate the plant is stressed. Worry if the browning continues to move down the leaf toward the stem.
Stopping it coming back
Keep the soil consistently moist and avoid letting the plant sit in hot, dry drafts. Consistent care prevents these crispy edges.
