Dear j_a,
Not sure how many orchids you have but if you are growing inside then
it shouldn't be that many. How big of an area do you have? It needs to be
cleaned, wiped down from top to bottom.
Now I would move everything, saucers, trays, pots, tags etc., wash in a
bleach/vinegar solution 1/2 cup ea. to a gal of water.
Repot everything before returning plants to the growing area. I spray any
plant I repot with Physan/water.
Not sure of the best potting mix for indoors but it seems like most inside
growers water too often! I would use some horticultural charcoal in the mix.
Lots of luck,
--
Cheers Wendy

gah! rot below the medium. grrr. done the H2O2 thing; done the
cinnamon thing; lost two plants (one a seedling that i thought was
getting better, and the phal bellina from [insert name of large east
coast orchid grower which shall remain nameless--no one on here] that
started it all); now my Br. Lancer clone has it. did the H2O2 thing
and cut away the bad parts and cut the spikes off and sprayed with a
copper fungicide (all i had)--and now i'm paranoid the whole
collection's got it.

besides physan 20, what could i use as a prophylactic spray/drench on
the rest? these plants are in my living room so i don't want to go
too toxic; fan on them for 8 hrs a day; the rest of the time the heat
pump's running with two vents directly below the plants.

AND my african violets have powdery mildew. i think i'm just going
to switch to cut flowers.
