Check these first

  1. Check if the soil is soggy or waterlogged.
  2. Look for signs of drainage issues in the pot.
  3. Evaluate the amount of light the plant receives daily.

Likely causes

  1. Overwatering

    Most likely

    How to tell: The leaves turn yellow and feel soft or mushy. The soil stays wet for a long time and may smell slightly sour.

    What to do: Let the top inch of soil dry out slightly before watering again. Ensure your pot has good drainage holes so excess water can escape.

  2. Insufficient light

    Possible

    How to tell: The lower leaves turn yellow and the plant looks stretched out. It may stop producing flowers.

    What to do: Move the plant to a brighter location with bright, indirect light. If it is in deep shade, it will struggle to maintain its foliage.

When to worry

It is normal for the very oldest leaves at the base to yellow and drop as the plant grows. If the yellowing is happening on new growth or across the whole plant, it is a problem.

Stopping it coming back

Ensure your plant gets bright, indirect light and avoid letting it sit in standing water. Use a well draining potting mix to keep the roots happy.

Questions people ask

Should I cut off the yellow leaves?
Yes, you can snip them off with clean scissors. This helps the plant focus its energy on healthy growth.
Is my plant getting too much sun?
Indian tobacco likes full sun to partial shade, but if it is in intense, direct afternoon heat, the leaves might bleach or yellow. Try moving it to a spot with afternoon shade.
