satinjade: is or are they cymimbidiums not sure on spelling. I've got mine in 20 lte pots filled with a really course potting mix nearly bark, need to have 3 green bulb, before they will flower and where we are we need to water heaps in the summer which is our Jan & Feb to get good spikes. Hope this helps
skipinnz: I have cymbidiams growing and all I do is tie/attach them to a tree trunk in the back yard and they eventually "root" and stay there on their own. You can buy a special potting mix for orchids, and that would be the best way to go, but of course Im talking australia...tropical australia where orchids grow wild.
