Hello, my bourgainvillea leaves have yellow dots with red/brown edges. I'm not sure if this means I'm over/underwatering or whether this is a fungal infection. I've added a photo so you can see exactly what I mean. Any advice would be appreciated. Thanks

It's definitely possible, I hadn't thought of that. I was worried it was a disease or something so cut off all the leaves to stop it spreading. Possibly a bit of an over-reaction! Thanks for your help Bamboo

Well it may also be bacterial leaf spot, which is spread by water splash - for that you remove affected leaves and only water from below to prevent splash transmission - but it does look more like burning. Trouble is the photo's a bit blurry.

That looks as if water has splashed the leaves, or dropped onto them, while in very hot, full sunlight, and has burned those spots. Is that possible?
