Why is my Japanese wisteria dropping leaves?

Check these first

  1. Feel the soil to see if it is dry.
  2. Inspect the stems for signs of wisteria scale.
  3. Check if the plant was recently moved.

Likely causes

  1. Drought stress

    Most likely

    How to tell: The leaves turn crispy and brown at the edges before falling off. The soil feels bone dry to the touch.

    What to do: Water the plant deeply until moisture runs out of the drainage holes. Maintain a consistent schedule of watering every 3 to 7 days to keep the soil moist.

  2. Transplant shock

    Possible

    How to tell: Leaves drop shortly after you move the plant to a new location or repot it. The plant looks otherwise healthy but is shedding foliage.

    What to do: Keep the plant in a stable environment with plenty of direct sunlight. Avoid fertilizing for 4 to 6 weeks while the roots establish.
