Do you know the name of your Vanda and how much light/water/fertilizer is it receiving?

Hi Junebug, it is V Roberts Delight, I also have a V Siriporn Pink that has the same problem. I have a tunnel where my Vandas grow (+-100) shade cloth 50% & plastic. They get water twice daily and fertilizer 1 a week. Misting system keeps humidity at 70%. I am in Sub tropical South Africa. thanks

I did a little research and found that V. Roberts Delight is a strap leaved Vanda, but couldn't find info. on your other one. The strap leaf varieties like partial shade and all Vandas like frequent root misting and good air circulation. Are your roots potted or allowed to dangle? You mentioned shade cloth and plastic. Is there sufficient air circulation. Was the (+-100) the temperature of your growing environment? If so, then my guess would be that they're either getting sunburned, cooked or need more air circulation. I'm no expert and have never used shade cloth so I don't no if 50% would be sufficient for this type of Vanda. Maybe some other OB members would like to chime in.

It looks like its getting enough light and enough water. Is that plastic covering it up from evening rains? Do you have a pic showing the roots?
