Q: I have notice my Euonymus is turning yellow and there are white little specks on the leaves. What is it and what do I do?
A: What you are seeing on the leaves is most likely Euonymus scale. They look like little white bugs and do not fly. They survive by sucking out the moisture and nutrients from the plants leaves and can destroy an Euonymus if not addressed.
It's best to spray with some sort of horticultural oil (dormant, neem etc.), and as always follow the instructions on the bottle.
