We have a large, 25 + yr. old Cypress on the North side of our property and it appears to be, overal, turning brown. There is a large moldy patch on one of the trunks. Last year, the arborist that pruned it, pruned it rather hard - meaing he cut it back very short. Is there something I can do to green it up again, or is it dying? Your input is appreciated!
Doesn't sound good; most cypresses won't regrow from hard pruning. Can you post some photos? The species of cypress can be important.
Possibly Chamaecyparis lawsoniana dying from root rot, if not killed by being whacked back. Once a conifer goes rusty brown (and crispy) it is over. The exception is kinds that normally go bronzy etc. during the winter, the leaves of these however remain fresh rather than becoming dry.
