Where Do Scales Come From?

Scale will attack any plant, but they are more attracted to plants that are weakened. I would check the plant to see if it might be under stress from something (under-watering, lack of nutrients, etc.) and correct this while also treating the scale infestation. We recommend treating with neem oil, as it is very effective against these pests.
