 Fungus or Virus?
I was given some orchids as housewarming presents a couple of years ago. They are all phalaenopsis and have done well. But in the past 6 months, they've all had white patches show up on their leaves and their leaves look grainy with them. I thought maybe they were just getting dry (low humidity) so I was water spraying them. Now I am wondering, are these scales? In the last month, I am also now seeing the tips of leaves turning yellow to brown to black. So I am thinking there is definitely something wrong. The photos are at photos.yahoo.com/wisechild9
Just today I have dusted 3 of them with cinnamon to see if that will change anything. Please help! |
