I was hoping someone here could help. For the last month, a round about 10 year old Grevillier has been dying. I can't say which type exactly, but it's the most common one I ever see in gardens. It's getting browner by the day!
It's been quite happy up till now. It can't be drought as we had a lot of rain in August.
Maybe too much rain in August, resulting in some sort of fungal disease? Given its Australian origins, that would not surprise me. Phytophthora is perhaps the most likely disease, most Australian plants are susceptible to it.
