Philadelphia fleabane · Erigeron philadelphicus

Why is my Philadelphia fleabane dropping leaves?

It is less common for this plant to drop leaves, but it usually happens when the soil stays too wet or the plant gets too hot. Check the soil moisture first to see if the roots are sitting in soggy dirt.

Check these first

  1. Feel the top inch of soil for moisture.
  2. Check the drainage holes for clogs.
  3. Inspect the leaves for signs of wilting.

Likely causes

  1. Overwatering

    Most likely

    How to tell: The lower leaves turn yellow and soft before falling off. The soil feels constantly damp or muddy.

    What to do: Stop watering immediately and let the top 2 inches of soil dry out. Ensure your pot has drainage holes so extra water can escape.

  2. Heat Stress

    Possible

    How to tell: Leaves wilt and drop during the hottest part of the day, especially in midsummer. The plant looks generally tired.

    What to do: Move the plant to a spot with partial shade during the afternoon. Water in the early morning to help the plant handle the heat.

When to worry

A few leaves dropping after you move the plant is normal as it adjusts. If the whole plant is losing leaves rapidly, it is a serious sign of root distress.

Stopping it coming back

Keep the soil consistently moist but never soggy, and provide good airflow around the foliage.

Questions people ask

Should I fertilize a plant that is dropping leaves?
No, avoid fertilizing until the plant recovers. Adding nutrients to a stressed plant can burn the roots.
Will the leaves grow back?
The plant will grow new foliage once the conditions improve. It will not regrow leaves on the bare stems.
