Canna lily · Canna × generalis

Why are my Canna lily leaves getting brown tips?

It is less common for Canna lilies to have brown tips, but it usually happens when the plant is not getting enough humidity or consistent moisture. Check your soil moisture first to see if the plant is drying out too much between waterings.

Check these first

  1. Check the soil moisture with your finger to see if it feels dry.
  2. Inspect the air around the plant for drafts or low humidity.
  3. Look for any signs of pests that might be stressing the leaves.

Likely causes

  1. Low Humidity

    Possible

    How to tell: The leaf tips turn crisp and brown while the rest of the foliage looks healthy. This often happens in dry indoor air or during very hot, windy spells.

    What to do: Mist the leaves daily with a spray bottle or place the pot on a tray filled with pebbles and water. Keep the plant away from direct air conditioning vents or heaters that dry out the air.

  2. Inconsistent Watering

    Possible

    How to tell: The soil feels dry to the touch several inches down. The plant may show signs of stress because it cannot keep up with its high water needs.

    What to do: Water your Canna every 2 to 4 days to keep the soil evenly moist. Ensure the pot has drainage holes so excess water can escape.

When to worry

Brown tips are rarely fatal, but they indicate the plant is struggling to stay hydrated. If the browning spreads to the whole leaf, you should adjust your care routine immediately.

Stopping it coming back

Maintain a consistent watering schedule and keep the soil moist at all times to prevent the plant from drying out.
