Euonymus Scale on heat stressed plants
Our Euonymus fortunei has enough water but can't overcome the extreme temperatures to protect itself from Euonymus Scale. And, the poor thing has a bad case. The ladies are the brown bits and the gentlemen are the white ones. The Unive rsity of Kentucky Ag site has a good summary and advice for treatments. Since I won't spray poisons during butterfly season, I'll cut it back to the trunk and do harsh water treatments to remove as much as possible until I can do more in early winter. It can become invasive ( Invasive.org ) in some areas such as PA - also zone 7 , but it has not in our yarden. Spellchecker has some amusing alternative choices for Euonymus ;-)
