Smallish plant, one or two years from flowering, I guess.

It is dropping leaves. It had nine or so leaves, there are now five
green leaves and two that are turning yellow.

It is now winter. The indoor humidity is about 40-50% at a steady
22-23C. The plant is getting about 35kLux of sodium-based (yellowish)
light. I water it twice a week, the roots look ok to me.

Help! What is happening? I haven't changed anything AFAIK. The
plant has been happy the last fourteen months or so.

Geir

Is it potted? If so, in what?

My first instinct was to say you're not watering often enough, but that is
probably because around here, vandas are grown "bare in the basket" and
watered daily [2x/day during the worst heat of summer]. I wouldn't know if
2x/week is enough for one in a pot, never having tried it.

Next thought was fungus. It wouldn't hurt, and might help, to spray it with
hydrogen peroxide. The usual recommendation for spraying peroxide for
"general hygiene" seems to be 4 oz/gallon [of the 3% solution most commonly
sold in drug stores], but I have seen it used full strength without harm to
plants.

Yes. It is in a 22cm/9in clay pot with pieces of fir bark about 1-3 in
large. There is lots of air in there, for fear of rot.

probably because around here, vandas are grown "bare in the basket" and
watered daily [2x/day during the worst heat of summer]. I wouldn't know if

Well, the fir bark is totally dry when I water. I will try to step up
the watering and see if it helps.

Next thought was fungus. It wouldn't hurt, and might help, to spray it with
hydrogen peroxide. The usual recommendation for spraying peroxide for
"general hygiene" seems to be 4 oz/gallon [of the 3% solution most commonly

I will try to get hold of some tomorrow.

Could it be fertilizer related?

Geir

Your initial post has apparently expired, but from memory, I don't think the
symptoms you reported would be fertilizer-related.

Ok, well, the vanda is now in a 400 lux bathroom environment which is
kept at 26C or so, and getting water about once every day. It looks
like it has stopped going yellow, and the roots in the bottom of the
pot are slightly moist before I water again. The top roots are dry and
white.

I can't get any more light in there. Will I get a problem if I keep it
in the bathroom two or three more weeks?

Geir

I wouldn't think so. We generally try to give stressed-out plants extra
shade while they recuperate from whatever stressed them out. You probably
won't get flowers without more light, but for the long-term health of the
plant, it should recuperate before you let it flower anyway.
