Help with unknown plant disease.
Hello, I have 2 x Hardenbergia violacea and both are suffering from the blueish powdery covering you can see in these images. It's quite fly away and there is a light misting of it everywhere when windy. it's sticky to touch. Thank you, Tamara
Thank you for contacting Yates.
Hope this helps and happy gardening :)
