Strange leaf spots on vanda pr. mikassa - Orchid Board

Daemos · #1 04-20-2008, 04:01 PM

Saw these odd spots today. This vanda has been mistreated for a while. No fert and bad watering. Are these spots caused by an infection or a nutrition problem? Plant has also been sunburned severly

sorry for the photo quality. Didn't had a camera at hand.

The large marks look like a sun burn... are you talking about the tiny dots? My Vanda and Ascocenda get these. I've seen them on Vandas and Ascocendas at orchids shows too. Not sure what they are but they don't seem to be harmful or deter growth.

Got the tiny spots myself as well and everything goes fine. Its really about the large brown stripe like spots.

Ive heard of viral infections giving the same symptoms thats why I wonder. The plant started dropping lower leafs in a rapid rate until now. If its sunburn then everything is fine, if its viral I wish my friend a good luck.

The questioned mark is burn from either light or a cold chill. The spotting can come from the parents. I think the plant is an Ascocenda, not a Vanda also by the name. The spotting comes thru in some hybrids if Ascocentrum curvifolium is in the parentage ( & others)

You are right. It was in bloom when bought and the flowers where purple but in a shape of anything I have ever seen. The spike was very thin and the flowers had very small and violy shaped leafs.
I am now certain its a cold chill. Since you cleared it up being a asconcenda I now understand what happend to it. Thank you very much.

If the plant is Ascocenda Princess Mikassa, the flowers are nearly the same size as a regular Vanda, 3 1/2 - 4 inch ( 90 - 100 mm ) depending on culture. What size were the flowers on your plant please.

That was a long time ago (plant was bought in september last year in full bloom) but the flowers where smaller then 5 cm and deepblue/purple

Daemos, it doesn't sound like Ascda Pr Mikasa, it could be Vascostylis Pine Rivers, would really need a pic of the flower to be sure though. There are a number of hybrids that fit the description.

Just thinking your plant may also be Ascda. John De Biase 'Blue'. This a common plant sold around the world.

That just might be. It didn't came from a special place or anything like that. Just a garden centre. They had a whole load of vanda's that just came in and this was one of them. Too bad it never bloomed again after it dropped its flowers. i told my friend to bring it over at my place and I would took care of it and get it to spike.
He wants to try it himself.

Do you have any photo of the plant you have in mind Roy?? Ill look on the net in the meanwhile trying to spare you the trouble.
