Re: Pohutukawa| Metrosideros excelsa| Lifespan| NZ Christmas Bush In Sydney they seem to thrive in the sandy coastal soils around Cronulla and Maroubra and similar areas. A big one here would be 6 m tall and spread about the same with a DBH of a metre or so. They were extensively planted as street trees by Randwick council maybe 30 years ago or so. I don't know how long they generally live here, but older specimens tend to die back and decline and become affeced by small longicorn larvae as you described in Bris.
Arborcraft should be able shed more light on this, they are prolific in his patch.
