Question
Hi, I was wondering if you can help me out, my plants (all of them) are developing this white matter on their leaves, I think its a fungus so will you please help me out in getting rid of it?

Answer
Hi Sulman,

The white stuff might be a fungus (powdery mildew), but more likely it is mealybug. If the white stuff looks like little bits of soft cotton, then it is mealybug.

Let me know what you think you have - you can e-mail a photo of it to me at [email protected] - then I will advise you on an appropriate treatment.

Regards,
Will Creed
