What's growing on my plants?

Asked June 22, 2019, 3:35 PM EDT

I have some bushes that cover the railing that leads down stairs to our basement. I just noticed that they have white stuff growing on the leaves and stems of the plant I've attached some pictures- is this treatable?

Montgomery County Maryland euonymus scale shrub

This looks like euonymus scale, a sucking insect on your euonymus shrub. This looks like a heavy infestation. Take a look at our website for more information and management.

At this point we'd suggest either removing it or cut the plant back to the ground and let it re-grow. Keep an eye on the new growth and treat as needed.
