Janet, no I didn't review your link. That clears it up nicely. I must have misread the reference I found at RHS. It's so sad to read about your loosing older/mature shrubs and trees. 30 years ago I had purchased 2 Chamaecyparis lawsoniana for my dad. One died 10-12 years ago, the other is doing fine. It was a hard winter but the more exposed one survived.
Unfortunately I can't follow your link Janice, it indicates the "file is damaged". Is this link to a pdf file?
