Why is my Epilobium montanum dropping leaves?

Check these first

  1. Check if the plant was recently moved.
  2. Feel the soil to see if it is completely dried out.
  3. Look for signs of pests like spider mites.

Likely causes

  1. Environmental Shock

    Most likely

    How to tell: Leaves fall off shortly after the plant is moved to a new room or location. The plant may look otherwise healthy.

    What to do: Leave the plant in a stable spot with consistent light and temperature. Avoid moving it again while it recovers.

  2. Extreme Drought

    Possible

    How to tell: Leaves wilt and then drop off because the soil has been bone dry for too long. The stems may also look slightly shriveled.

    What to do: Water the plant thoroughly until water drains from the bottom. Resume your regular schedule of watering every 3 to 7 days.

Questions people ask

Will the leaves grow back on bare stems?
Usually, leaves will not regrow on the same spot of the stem. The plant will eventually produce new growth from the tips.
Is leaf drop a sign of disease?
It can be, but it is more often related to environmental stress. Check the leaves for any spots or webbing to rule out pests or fungal issues.
