Wax Begonia · Begonia cucullata

Why are my wax begonia's leaf tips turning brown?

It is less common for wax begonias to have brown tips, which usually happens due to low humidity or salt buildup from tap water. Check your environment and water quality to find the culprit.

Check these first

  1. Check if the air around the plant feels very dry.
  2. Look for white mineral deposits on the soil surface.
  3. Review your water source for high mineral content.

Likely causes

  1. Low Humidity

    Possible

    How to tell: The leaf tips turn crispy and brown while the rest of the leaf remains green.

    What to do: Group your plants together to create a more humid microclimate. You can also place a tray of pebbles and water near the plant.

  2. Mineral Buildup

    Possible

    How to tell: A white crust appears on the soil surface and the leaf tips slowly turn brown.

    What to do: Flush the soil with distilled or filtered water to wash away excess salts. Switch to using filtered water for your regular watering routine.

Stopping it coming back

Questions people ask

Should I mist my begonia to help with brown tips?
Misting is not very effective and can encourage fungal issues like powdery mildew. It is better to use a humidity tray or a room humidifier.
Can I trim the brown tips off?
Yes, you can trim the brown parts with clean scissors. Just be careful not to cut into the healthy green tissue.
