Why are there bugs on my Indian tobacco?

Indian tobacco is a favorite snack for aphids, which cluster on new growth and suck the sap. Check the undersides of your leaves and the tips of the stems for these tiny, soft bodied insects.

Check these first

  1. Inspect the undersides of leaves for clusters of tiny bugs.
  2. Check for sticky residue on the stems or leaves.
  3. Look for fine webbing between the plant parts.

Likely causes

  1. Aphid infestation

    Most likely

    How to tell: You will see small green or black insects clustered on the tender new growth. They often leave behind a sticky residue called honeydew.

    What to do: Spray the plant with a gentle stream of water to knock them off. If they persist, apply insecticidal soap every 5 to 7 days until they are gone.

  2. Spider mites

    Possible

    How to tell: Look for fine, silky webbing between the leaves or stems. The leaves may also appear stippled or pale.

    What to do: Increase the humidity around your plant to discourage mites. Wipe the leaves down with a damp cloth and use neem oil if the infestation is heavy.

When to worry

If the plant is covered in bugs and the leaves are curling or yellowing, it is time to act immediately. A few stray bugs are normal, but a full colony will weaken your plant quickly.

Stopping it coming back

Keep your plant healthy with consistent moisture and check it weekly for early signs of pests. Avoid over fertilizing, as excess nitrogen can attract aphids.

Questions people ask

Can I use dish soap to kill the aphids?
Yes, but use a mild, non detergent soap mixed with water. Avoid soaps with degreasers or perfumes, as these can burn the leaves.
Will the aphids kill my plant?
If left untreated for a long time, they can stunt growth and weaken the plant significantly. Catching them early makes them very easy to manage.
