About Dieback

Susceptible Plants

Phytophthora dieback kills a large number of garden plants, horticultural plants and over 2300 native plant species in the south-west of Western Australia. In particular Banksia, Dryandra, Hakea, Jarrah, She-Oak, Hibbertia and Grass trees are susceptible. For more information please visit The Centre for Phytophthora Science & Management website.

Please note that a number of WA native plants are resistant to Phytophthora dieback, but may be having disease issues due to water stress, toxicities or other plant diseases. These plant species include Red Gums, Tuart's, Flooded Gum, Wandoo and Karri trees.
