- Check the drainage holes to ensure they are not blocked.
- Look at the overall leaf color for signs of dehydration.
Likely causes
Underwatering
Most likelyHow to tell: The tips turn crispy and brown while the rest of the leaf feels dry and brittle. The soil will be pulled away from the edges of the pot.
What to do: Water your plant thoroughly until liquid runs out of the drainage holes. Stick to a schedule of every 7 to 14 days, adjusting based on how fast the soil dries.
Low humidity
PossibleHow to tell: If your home air is very dry, the tips of the long, sword like leaves will dry out. This is common in winter when heaters are running.
What to do: Group your plant with others to create a microclimate. You can also place a tray of water and pebbles near the base to increase local humidity.
When to worry
Brown tips are mostly cosmetic and not a sign of a dying plant. You only need to worry if the browning starts moving down the entire length of the leaf.
Stopping it coming back
Maintain a consistent watering rhythm and keep the plant away from direct heat vents.

Questions people ask
- Can I trim the brown tips off?
- Yes, you can trim them with clean scissors. Cut just outside the green tissue to keep the leaf looking natural.
- Does my flax need misting?
- Misting does not really help with humidity. It is better to use a pebble tray or a humidifier if your home is very dry.
