Greetings -
Whether you have one or two orchids, or have suddenly found yourself with a dozen (it can happen!), I'd really encourage you to check out your closest local orchid society or club.
Many are affiliated with the American Orchid Society, and thus have access to lots of educational materials.
To my surprise, our local orchid society turned out to be *not* a snooty bunch or highbrows, but rather a casual, friendly group of 'plant geeks'. I think the first meeting more than made up for my $10/year membership - I was asking about a languishing Miltonia...and was bluntly told "you can't grow that HERE!" Too hot in south Louisiana, who'd have thought?
When I first joined, people actually gave me divisions, and thanked me for taking them!
A good place to get good cultural advice - when I knew next to nothing, I found that vendors could tell me anything, and I'd believe them (thus, the Miltonia).
Regards - Nancy
