Wax Begonia · Begonia semperflorens

Why is my wax begonia dropping its leaves?

It is less common for a healthy wax begonia to drop leaves, so this usually happens when the plant is stressed by sudden changes in its environment. Check the soil moisture first to see if you are overwatering or underwatering.

Check these first

  1. Touch the top inch of soil to check for dampness.
  2. Inspect the plant for cold drafts or heat sources.
  3. Look for signs of soft or mushy stems.

Likely causes

  1. Overwatering

    Most likely

    How to tell: The leaves turn yellow or mushy before falling off and the soil stays soggy for days.

    What to do: Let the top inch of soil dry out completely before watering again. Ensure your pot has drainage holes so excess water can escape.

  2. Temperature Shock

    Possible

    How to tell: Leaves drop suddenly after the plant is moved to a drafty area or a spot near a heater.

    What to do: Keep your begonia in a stable spot away from air vents, radiators, or cold windows. Maintain a consistent temperature between 65 to 75 degrees.

When to worry

A few leaves dropping after you bring the plant home is normal as it adjusts. If the plant is losing most of its foliage, it is in serious trouble.

Stopping it coming back

Keep your watering schedule consistent and avoid moving the plant to new locations frequently.
