I don't think things look so bad........First, orchid mixes...especially bark mixes are not designed to hold water; they hold moisture and provide a place for the roots to climb around in, attach to, and draw moisture from. Your plant looks like is suffering from a lack of water, but there appears to be sufficient roots, and a new root starting, so I would not suspect a root rot problem, just a general lack of water problem. This problem was most probably started before you got the plant...It was probably sitting in water at the store and developing root rot - you indicated you trimmed the "rotted roots" off before you repotted it.

There appear to be sufficient roots on the pant for it to survive. Water the plant when it gets dry, soak it thoroughly (hold it under a stream of water and flood it) then allow it to become almost completely dry before you repeat the process. Don't put it on a time table, when it becomes almost completely dry, water it.

You indicate you have been fertilizing it almost every time you water it...for right now I would suggest not doing that. stop the fertilizer for a while until the plant has new roots, then fertilize at half the recommended strength about twice a month when the plant is growing. The plant is a Phalaenopis, so I would suggest a balanced fertilizer.....(10-10-10, 5-5-5, or similar)

I suspect when you change the watering habits, you will see an improvement in the general condition of the plant. Change will not come quickly, orchids do not grow fast, but change will come. You may loose that bottom leaf over time, but the new one coming looks nice and healthy.

I think you have the potential of a nice plant. Good luck

I second what Bill said. However, having grown Phals in NY for a long time, I always found straight bark difficult. I always mixed some sphaghnam moss in to the bark to hold some moisture.

You don't mention where you are growing this plant. I assume a window but what exposure? Southern, North, etc.

I would recommend sticking the pot in a bowl of water and leaving it for a few hours to help the bark to take up water. I always soak bark mixes before potting a plant. Phals need more moisture. You might run into problems over winter when the indoor air is very dry. I highly recommend adding some sphag moss to the surface of the bark to provide some humidity to the roots.

These plants grow naturally attached to trees. The roots get covered with debris, old leaves, mosses etc. Bark by itself is very dry.

The plant looks healthy as do the roots but it is becoming dehydrated. Soak the plant in some water to hydrate the bark and water again when almost dry.

It is summer. Phals love warmth and this is the time of year they make their growth. Winter is when they bloom. Give them a good summer and you will be happy this winter.

Good luck,
