Vanda- yellow leaves- old roots fell off.

[Orchid Davantage]

I will do my best. While it is on the mend, should I soak it twice a week for a shorter time? I mist my two other ones every day and dip them once a week. What should I do about this one? The new root is coming on the side, it makes it difficult to soak for an extended amount of time. It is in a bucket of water now, after that it is going to join all the other orchids in a sun room. It has lights and humidifiers.

We got four NOID vandas off of the raffle table at my orchid society; they literally had no root systems, the good ones had a half rotted root. They were infested with scale, so naturally they stayed outside, so we could take care of the scale first (they couldn't come indoors for the winter and ruin my valuable plants). The scale was gone, so now we turned our attention to getting a root system back. My husband has decided to make this his project. Even though we normally hang all of our vandas overhead, these are currently the exception. He has decided to use vase culture to establish a root system. It is working very well. He leaves water in the bottles (oberweis milk bottle and zip sauce bottle) and keeps the stem of the vanda above the water, so it doesn't rot. We are seeing new root growth and no leaf loss. If you have the space this may be a good option for you until you get a good root system.

If you need more detailed information on exactly what we're doing with our four let me know. There are also a ton of threads about vase culture and vandas on the OB.

I agree the plant is dehydrated and can be saved. And the good news is vandas can grow roots all year long.
