My favorite NOID phal needs help

[Mirranova]

Soaking the bark for 24-48 hours in room temp. water should suffice, you can also add a few drops of dish soap to it(helps it soak in). I also soak my bark with a few drops of Superthrive in the water, it helps with stimulating root growth. I would avoid fertilizer for a month or more after repot, and simply keeping it watered when it needs it will help it to produce some nice roots. I find after a repot my Phals have a growth spurt.

You can gently trim off anything that you are sure is dead. The key to repotting a Phal in keiki or spike is to be as gentle as possible, especially with healthy roots. Healthy roots if moved around to much or bent can develop tiny cracks that allow infection. Also the least amount of disturbance, the happier it will be with the repot. You want to make it happy, not stress it.
