Are there bugs on my Heath Milkwort?

It is less common for this plant to get pests, and they usually appear when the plant is already stressed by poor air circulation or dry conditions. Check the undersides of the leaves and the stems for any tiny webs or sticky residue.

    Possible

When to worry

If you see a heavy infestation covering the whole plant, it is time to take aggressive action. A single bug is manageable, but a colony can weaken the plant quickly.

Stopping it coming back

Keep the plant healthy with proper moisture and wipe the leaves occasionally to keep them clean.
