Trees and native bushes are now thought to have been damaged by a mysterious substance which decimated heritage roses at a Dunedin cemetery.
The results of tests to determine what damaged as many as 500 roses in the Northern Cemetery, some more than 130 years old, were expected to be released this week.
However, council parks operations manager Hamish Black yesterday said results were now expected to be released next month.
He yesterday revealed trees and native vegetation were also showing signs of damage.
"Further testing will include soil testing and testing of other plants in the cemetery to help identify the source of the problem," Mr Black said.
Heritage Roses Otago convener Fran Rawling said shewas pleased further testing was being done.
