How many roots does an orchid need to survive?

I've recently started growing orchids (phals, paphs, cattleyas, dendrobiums and vandas), and I ordered two beautiful orchids from an excellent seller on eBay (past experiences have been great), but was upset to find that all but one of the roots were rotten on both plants. They're both phalaeonopsis. I trimmed all the dead, rotten roots away, but now there's just one healthy one left, and the leaves are looking soft and droopy from lack of support. What can I do to save my orchids?! Is there anything I can put on the roots or the bark to stimulate or expedite new root growth? I'm too new to orchids to know this yet...but they're beautiful plants and I don't want them to die! My favorite one is in spike right now, so I haven't even seen it bloom yet! =(

If there are flower spikes, cut them off.



Use a small pot and repot into fresh orchid seedling mix. If you don't have that, use half and half mixture of orchid mix and peat.



Keep moist - mist leaves (but not the crown) until you see new root activity.



They should produce new roots and you can repot again later in the summer into a larger container.
