NZPPI has applied for exemption of seven cultivated Japanese cherry varieties from Auckland Council's Regional Pest Management ban.
The applications followed fertility testing research which was done over two spring and summers in 2022 and 2023 by Plant & Food Research.
The cultivars Kanzan, Shimidsu Sakura and Kiku Shidare Sakura were all exempted from the ban in 2023.
Temporary exemptions were given for Ukon, Shirotae, Tai Haku and Amanogawa while further research was undertaken.
Unfortunately Auckland Council have recently reversed their decision to include Ukon and Shirotae in their exemptions. These two cultivars, as well as Tai Haku and Amanogawa do not meet the Auckland Council standard and nurseries currently holding stock have until December 2025 to move these on to avoid financial loss.
NZPPI has been advocating for the exemption of various low fertility/ low sterile Japanese flowering cherry cultivars for some time now. Flowering cherries are a popular street tree in urban subdivisions and developments, as well as home gardens.
