I'm not sure what's going on with my Lilly Pillys, but they are developing whitish-grey patches on the leaves. I've looked at them under a magnifying lens but I cant see any insects that may be causing this. I also tried wiping/scraping it off, but it seems like it's embedded in the leaf itself so nothing comes off. I don't think it's powdery mildew. Can anyone help me identify what's going on here - and how can I treat them?
Hello @TingleFarm
Welcome to the Bunnings Workshop community. It's wonderful to have you join us and thanks for sharing your question about your lilly pilly.
I suggest having a quick look at this guide - How to diagnose a sick plant by @Noelle and How to diagnose and revive a sick lilly pilly by @Noelle. Would it be possible for you to post a photo of the body of the plant where the patch is very noticeable. Can you also please post a photo of the base of the plant as well. This will help us give a better diagnosis of your plant.
It's possible that it could be a combination of different factors that has caused your lilly pilly to get sick. A fungal or viral infection in combination with insect infestation. Waterlogged roots or perhaps an infection has been passed on from another plant.
Can you please tell us your watering and fertilizing schedule. Has there been any other activity that has been going around your lilly pilly? Any other information you can share with us would be very much appreciated. Once we have more information, we should be able to provide you with more advice.
If you have any other questions we can help with, please let us know.
Eric
