NoID Phal. recovering from crown rot

[Salixx]

Hi all

This might seem like a silly question, but I'll ask anyway.

I have a particular Phal that's been with me for a very long time... probably somewhere around 13 years. It's only bloomed a handful of times for me, one of which was last year. I was excited, since it is one of the first orchids I ever acquired and it's been so hesitant to bloom. Then, disaster struck not long after the last blooms faded. The top leaves started to wilt. I'm a forgetful gardener, some might say even neglectful, so I naively though it needed more water. When the top, newly growing leaf yellowed and died, I knew I was in trouble and, sure enough, most of the other leaves followed suit as the crown rot became even more evident. I was always careful when watering not to allow water to pool in the leaves, but I suspect from overflow from another plant hanging above it might have been the culprit.

To my relief, the phal survived. The bottom most leaf is still alive, fleshy and intact and it shot a keiki of from its base shortly after I got the rot under control and vigorously grew from there. This is where my question starts. Firstly, the leaf from the old, main plant is still there- I've left it in hopes of it still providing for the newer offshoot. It is making the keiki grow a little funny- the leaves are slightly whorled instead of bilateral-like growth of leaves growing opposite each other. I don't really care if the plant is a little weird looking, but am I right in leaving the old leaf attached until it dies on its own? Or should I remove it now?

I was also wondering how long, after an event such as crown rot, it might take the plant to bloom again? The keiki is almost as big as the original plant was at the time the rot started, but I'm worried it will now be almost another decade before I'm allowed to see blooms again since it was already a reluctant bloomer.
