    Hi P1,

    I'm slowing catching up on posts...sorry to no have answered sooner. Brassavola Moonlight Perfume is a primary hybrid that is, a cross between two species of Brassavola nodosa as Gin mentioned and Brassavola glauca.

    Yellowing leaves is typically a sign of a water problem. Either too much or too little. If you aren't sure which it is, you can always unpot the plant and examine its roots. If the mushy or rotting, it's too much. If they're dry and crispy, it's too little. They should be greenish white or creamy colored and firm.

    Gin's right - Brassavolas need to dry out between waterings. But it might not just be your watering frequency that's at fault. If the mix is old and has broken down, it might be holding too much moisture. If that's the case, you should repot in fresh media that allows good drainage.

    yikes, up-rooting it sounds pretty scary, but that advice also makes alot of sense. i guess i'll try to have to work up my courage and see what i can do!

    thanks for the all the help so far, and anything else anyone wants to add would be very welcome. i'll update with more questions/problems/answers as they come up! XD

    Unpotting isn't as scary as it sounds, and it's a tremendous learning experience. Soak the pot for 5-10 minutes before you do. It will make the roots much more pliant. Figure all the old potting material will be tossed, so make sure you have some bark mix ready to go (soaking in water as well.)

    Carefully work any potting material off the roots. Gentle rocking will coax stubborn pieces of bark off roots. Nothing to jarring, or you might break the roots. Some will fall off anyway. Don't freak out. The plants don't mind a little root loss. If roots are rotted and mushy, cut them back with sterile scissors to a healthy point. Same as if they're brittle and dessicated. Only leave healthy roots on the plant.

    If the root mass was crowded in the pot, you might need to go up a pot size. If you cut away a lot of dead roots, you might want to step down a size. Have the pot choices available - either one size up or down - before you begin. The roots ideally want to nudge the sides of the pots, but not jam down into them, or reversely swim in the middle of a huge pot.

    Use some styrofoam peanuts in the bottom of the pot to aid drainage, and then add a thin layer of well-soaked potting mixture. I then try to loosely pack the center of the root ball with mixture, and set it into the pot. Fill in around the outsides of the root mass, tapping the potting mixture down to settle it around the roots securely, but don't shove too hard - you want to leave some air spaces and don't want to break any roots. Pottling clips can help secure a newly potted plant. You can also stake it.

    Be sure to let us know how it goes!

    Ok, thanks for the advice! there is a bud that is starting to open, so once that flower falls i will have some new bark, and i will investigate throughly and report back!

    EDIT: oh, and about the dead, brown, crispy leaves: will they fall off, or do they need pruned?

    just an update incase anyone cares: i haven't repotted it yet, but i have deduced that low light is at least a part of the problem. tomorrow i am ordering a new, brighter light, which should be here by the weekend. and not a day too soon: another leaft is tuning yellow!

    once the flower falls, i will probibally report back here for more help/advice.

    thanks!
