Cedars are native to North Africa, India and the Middle East, all dry regions. They tend to grow very fat and soft on damp Irish soil and have a tendency to break in strong winds. Often dropping heavy branches or breaking the top off. Also they will suffer some needle damage in coastal areas and close to the sea will suffer salt damage.
The Monterey pine, Pinus radiata, is the best in such places. If you want to chance a cedar, the deodar cedar from the Himalayan region is likely to be best, planted in the least exposed place you can give it. Strong winds keep trees short.
