Common toadflax · Linaria vulgaris

Why are my Linaria vulgaris leaf tips turning brown?

Brown tips on your toadflax are less common and typically indicate that the plant is struggling with low humidity or inconsistent watering. Check if the soil has become bone dry for too long.

Check these first

  1. Feel the soil to see if it is completely dry.
  2. Check the location to see if it is near a heater or vent.
  3. Observe if the browning is spreading inward.

Likely causes

  1. Underwatering

    Possible

    How to tell: The tips of the leaves become crispy and brown while the rest of the leaf feels dry. The soil pulls away from the edges of the pot.

    What to do: Water the plant thoroughly until moisture runs out of the drainage holes. Resume your schedule of checking the soil every 7 to 14 days.

  2. Low Humidity

    Possible

    How to tell: The leaves look dry and brittle at the edges despite the soil being moist. This often happens in very dry indoor environments.

    What to do: Move the plant to a spot with better air circulation. You can also place a tray of pebbles and water nearby to increase local humidity.

When to worry

Minor browning on the very tips is common in dry weather. Worry if the brown patches start to cover more than half of the leaf surface.

Stopping it coming back

Keep the soil moisture consistent and avoid placing your toadflax directly in the path of hot air vents.
