Question
I have had several large (approx 5ft) euonymous shrubs as part of my landscaping for several years.  3 of them on 1 side of my home have been dropping leaves the past couple of years so fast that by now they look barren and sick.  They're getting the same amount of water/sunlight as all the others, and I don't see any mites on them.  Is this a typical sign of some disease that I can counteract?

Answer
Hi Jane,
Thanx for your question.  It sounds like either anthracnose which is a bacterium or scale which is an insect.  I have included a website from Clemson University which goes into extensive detail about pests of Euonymus and the treatment.  I hope this helps.
Tom
