Our OCE took a look at your question -
"There looks to be a major issue with the root system in that repotting was delayed. By delaying the repotting, there are not enough live roots left in order to keep the leaves nice and plump. They are wrinkled showing an overall lack of adequate moisture.
The new pot is way too big!! With only a few small live roots, a smaller pot is needed. A pot small enough to hold the root system snuggly, no extra room. That only makes the plants recovery very slow.
Water plant in a smaller pot every three days. Low light, no fertilizer. Expect new roots in 4-6 weeks. It should recover. As it is right now, there is very little hope for that!"
Back to Ursula -
It might be a good idea to read through our "Supermarket Orchid thread" and Bill's
thread "New group of Phalaenopsis and modern ways of repotting. "
