Trim down cypress exposing dry/drown core
I moved to a new house recently with a cypress (I think) growing up against the livingroom window (see photo).
I'd like to take it down in height (so I can open the window) but as I'm sure is common, it is brown and dry inside (I would include a photo of that too but it appears you can only add one photo to a forum post here?)
In cutting it down, I would expose a brown, dry circle on the top which isn't a problem if it will green up over time. Is anyone able to advise if that will happen or will the exposed part stay brown and dry?
