Common boneset · Eupatorium perfoliatum

Why is my boneset losing its leaves?

It is less common for boneset to drop leaves, and this usually happens due to severe stress from extreme temperature changes or root issues. Check the soil moisture and the plant's location for sudden drafts first.

Check these first

  1. Check the base of the stems for mushiness.
  2. Look for signs of pests like spider mites.
  3. Verify the plant is not sitting in standing water.

Likely causes

  1. Root Rot

    Most likely

    How to tell: The leaves turn yellow or brown and fall off while the stems look mushy or dark at the base.

    What to do: Remove the plant from its pot and trim away any black, mushy roots. Repot in fresh, well draining soil and ensure the pot has adequate drainage holes.

  2. Temperature Shock

    Possible

    How to tell: Leaves drop suddenly after the plant is moved to a new location or exposed to a cold draft.

    What to do: Move the plant to a stable environment away from windows that get cold at night or doors that let in drafts. Keep the temperature between 65 to 75 degrees Fahrenheit.

Questions people ask

Does boneset go dormant?
Yes, in its natural habitat, it may lose leaves as it enters dormancy in the winter. If this happens, reduce water until spring growth begins.
Can pests cause leaf drop?
