Why is my Indian tobacco dropping its leaves?

  2. Inspect the plant for signs of wilting.
  3. Assess the location for excessive heat or direct sun exposure.

Likely causes

  1. Underwatering

    Most likely

    How to tell: The soil feels dry to the touch and the leaves look wilted before they fall off.

    What to do: Water your plant thoroughly until liquid drains from the bottom. Maintain a schedule of every 2 to 4 days to keep the soil consistently moist.

  2. Heat stress

    Possible

    How to tell: Leaves drop quickly when the plant is placed in an area that gets too hot or receives intense afternoon sun.

    What to do: Move the pot to a spot with partial shade during the hottest part of the day. Ensure the plant has good air circulation to keep the foliage cool.
