Hard white spots on leaves
I noticed today that several of my phals have small, hard white bumps
on the top of some leaves. Just a few. It's possible that they have been that way for a while. I only noticed it today because I decided to put my glasses on and check for new spikes. Without my glasses everything looks great! The plants look fine and are either in flower or growing spikes. Help would be appreciated. |

Hard white spots on leaves
hmm. do they come off? are they stuck on or part of the leaf? are
they hard shell scale or just ookiness from hard water? also, are they stray potting bits that have gotten stuck on? i occaisionally am given a heart attack by a stray piece of sphag that has lodged somewhere and i think "eek! scale!" then i poke it and realize it's sphag. have you tried wiping yours off? water first, then rubbing alcohol. see if it makes them run away. ;) --j_a |

Jane,
The spots may not have been caused by the same reason. In the lower photo these white spots on top look like they have been there for at least a while. They will remain on the leaf, no wiping them off. The one spot seems to have a trail off the edge of the leaf. The plant has grown on with a small indent at the edge. It could have just been an inadvertent injury or scratch. One thing to consider is that the orchid was visited by a slug. The underside may have marks where the lil pest was munching? If there are slugs hiding down in the media during the day, you can just set the pot in water that covers all of the media. In about 15-30 minutes they will at the top of the plant waiting for a helicopter to save them from the flood! If it turns out be slugs you can use a product with iron phosphate (such as Slug and Snail Bait distributed by Lilly Miller Brands) to spread around the growing area.

There was an indentation left from those that came off. I also thought it might be potting medium, but I don't think it would get that hard, would it?? I do sometimes spray the medium because the bark chips just allow all the water to go right through. I use a mix of chips and moss. I never get water on the leaves. Good news is the plants are looking fine. Growing new spikes and leaves. |

I have to agree with a previous poster, that not all of the spots look to
have the same cause. Most look like mechanical damage, to me, but if they are coming off, that's not it. Sorry not to be of more help. Kenni "Jane" wrote in message ...
