Orange/rusty spots on citrus leaves

8 years ago

Hi There,


Just like the title suggests, I noticed some orange/rusty spots on my dwarf Valencia plant. I have been spraying eco oil and neem oil so I don't think it's aphids.


The weather here in Sydney has been very very cold, and a couple of nights we even had frost. I have been covering it with a frost protection cloth (sometimes during the day too when I am in a rush to work and don't have time to remove it).


So I've been thinking it could be some cold damage or perhaps even scales, but I'm not sure.


Could you please advise?


many thanks.
