    I just discovered hydrangea scale on my 30+ year old Cornus kousa. I cut off and disposed of all branches where I could see the white scale egg cases. Also removed a few dead branches. What next? Should I treat the tree with dormant oil in the fall? Are there other treatment option?

    Any suggestions appreciated.

    Thanks!

    Just bumping this one up, in case someone who knows the answer missed it.
