Azure bluet · Houstonia caerulea

Why are my Houstonia caerulea tips turning brown?

Brown tips are less common for this plant and typically happen when the air is too dry or the mineral content in your water is too high. Check the humidity levels around your plant first to see if the air is drying out the foliage.

Check these first

  1. Feel the leaf tips to see if they are dry and crispy.
  2. Check the air temperature to ensure the plant is not near a heater or vent.
  3. Observe your watering water source to see if it is heavily treated.

Likely causes

  1. Low Humidity

    Most likely

    How to tell: The tips of the leaves become crispy and brittle while the rest of the leaf looks healthy.

    What to do: Group your plants together to create a more humid microclimate. You can also place the pot on a tray filled with pebbles and a little water.

  2. Water Quality

    Possible

    How to tell: Brown tips appear even when the soil is kept consistently damp.

    What to do: Switch to using filtered or rainwater instead of tap water. Tap water often contains salts or chlorine that can build up in the soil and burn the leaf tips.

When to worry

Worry if the browning continues to move inward toward the center of the leaf. Minor browning on the very edges is often just a reaction to indoor air conditions.

Stopping it coming back

Maintain consistent soil moisture and keep the plant away from direct drafts or heating vents.

Questions people ask

Will the brown tips turn green again?
No, the damaged tissue will not recover. You can trim the brown parts off with clean scissors if they bother you.
Does misting help?
Misting provides only temporary relief and is not as effective as using a humidity tray or a humidifier.
