Worried about root rot, use peroxide?
Hi. I know very little about orchids, but recently I told relatives I'd like some for my 49th birthday and suddenly I've got seven -- four dens and three phals.
My wife got me the phals. They must have been on sale for Easter, because they came in a basket with fake grass on top. They were just sitting in the basket indoors for about a week while I shopped for suitable orchid pots. When I finally took them out of the basket, I discovered they'd been grown in sphagnum, probably a semi-hydro method. Sphag was sopping wet.
Problem was, at least one of them looks like the roots have started to rot. In the new pots they'll be growing in a combination of orchid bark, pumice and charcoal. Of course, I'm not going to water them for a while.
What I'm wondering, though, is if I should try giving them a dose of drug store hydrogen peroxide. Not straight out of the bottle. I'd use about a tablespoon per gallon of water.
If I don't do this, what else should I do to give these phals a fighting chance?
