One "mistake" I made at a show when I was newer to orchid growing was buying a particular Catasetum. This specific plant had crazy root growth over and out of the pot and I thought at the time that this was an encouraging thing. Well, when I got home and took it out of the pot, the smell of decay assaulted me and it was so root bound around the decaying sphag that it took me forever to repot it. I had to cut so many dead roots. The plant took a major hit in health and is actually still in recovery.
I learned 2 lessons in plant shopping from this -
1) Sometimes if the roots are growing out of the pot, it is because they are trying to escape the environment of the pot.
2) Don't get overly excited if you find that rare orchid you have been looking for at a show. Keep your head and critically evaluate the plant.
