is my Angophora costata sick or dying?
I have a beautiful large Angophora Costata, but I am noticing that it's leaf canopy has become quite sparse and thin and its green leaves are starting to show red coloured spots - is my tree sick or dying? If so any tips on what I can do? or is this a common thing this time of year early Sept?
Appreciate your help!
Hi Adam It may be that your tree is infected with Myrtle Rust. Here is a link to an article from NSW Dept of Primary Industries. https://www.dpi.nsw.gov.au/biosecurity/plant/insect-pests-and-plant-diseases/myrtle-rust.
