Salsify · Tragopogon porrifolius

Why are there bugs on my Salsify?

Seeing small insects on your Salsify is usually a sign of aphids. They love to cluster on tender new growth and flower buds, sucking the sap out of your plant.

Check these first

  1. Inspect the undersides of the leaves for clusters of tiny insects.
  2. Check the flower buds for any sticky residue or moving bugs.
  3. Ensure the plant is receiving at least 6 to 8 hours of direct sunlight.

Likely causes

  1. Aphid infestation

    Most likely

    How to tell: Look for tiny green or black insects huddled on the undersides of leaves or near the flower buds. You might also notice sticky residue on the leaves.

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

  2. Environmental stress

    Possible

    How to tell: Plants that are not getting enough sun or are struggling with irregular watering are more attractive to pests. Check if your plant is in full sun.

    What to do: Move your Salsify to a spot with full sun. Ensure you are watering every 3 to 7 days to keep the soil evenly moist.

When to worry

It is serious if the aphids are causing the leaves to curl or the flower buds to fail to open. A few bugs are normal, but a heavy infestation needs quick action.

Stopping it coming back

Keep your Salsify healthy with consistent watering and full sun to make it less appealing to pests.
