Paph roots in bad shape - need help

[Ray]

Rooting powders are much too concentrated for use on orchids.

Get a liquid version like K-L-N or SuperThrive. Soak the entire plant for about an hour in a gallon of tepid water to which you've added about a teaspoon of the stuff.

Pot it up in some fresh, moist, airy medium, put it in a plastic bag to maximize the humidity, then keep it warm and shady.

If it's going to recover, it will.
