    Thanks. I checked the crown and sure enough the two top leaves seemed to have rotted and came right out when I pulled lightly on them. How do I avoid the crown rot? These vandas are all outside (hanging under trees) so get rained on and leaves and other debris in them. Do I rinse weekly with physan (or something similar)?

    Pour 3% hydrogen peroxide directly into the top of the crown every 2-3 days until it stops fizzing when you apply. I would also sprinkle some ground cinnamon into the crown. Being in Florida this is an issue that happens, I would suggest that come spring you start spraying a fungicide on a regular bases during our growing season. It is preventable at times but with all the rain we had towards the end last year it needs to be checked regularly.

    Concur with Jack. I would also suggest you cut the crown an inch below the last rotted fan and seal it cinnamon and ensure that water does not collect till it is completely dry and brown.

    If I cut the crown an inch below the rotted area, I will cut off the new growth/offshoot that is there. I'll try the hydrogen peroxide that Jack suggested and see how that goes first. Thanks.

    Jack, do you think I could do a fungicide treatment now since we still have been having a bit of rain? Or should I just wait? I just don't want any potential issues that may be lurking to get out of hand if I wait till April or so.

    I would say no as the hydrogen peroxide and the cinnamon will do the same thing with much less stress, we are finally getting some colder weather and they will have to deal with that. Check any other vannda's that are around this plant, I would also move it away from any other vanda's till you see new growth.

    While you treat for the rod with cinnamon,you can move this vanda under some cover place so the plant has some time to dry and heel the wound(the rod area)

    I did the same thing with my Phals that has crown rod .pour the cinnamon on conjunc of leaf .it stop the rod on time
