I have had this plant for a few years now. Healthy and blooms right on schedule. Question is, the roots are bound in the pot. I am thinking about re-potting, but read they will pout for years and they, like Dens., like to be rootbound.
Any experience/opinions?

Ted, except for a small species of Sobralia some years ago, the only other Sobralias I saw was in Ecuador, mostly on road sides. I think you are doing great with your plant. I have no idea what your next step is. Don't fix if it isn't broken?

One suggestion if I may Ted, I make it a practice of disturbing any orchid being repotted as little as possible no matter what it is.
Clay or plastic pot?
If clay and the roots are really pot bound, just break the clay away and pot up just a little bit. Do not go a couple of sizes larger.
If plastic, you could use a sheetrock knife with a sharp blade and cut right through that plastic. Just be very careful to put it down on a steady flat surface. Then peel back the pot by prying away the two sides of the pot and then gently get the base of the pot away. This might allow you to disturb the roots minimally. then if you have a nice tight root system, just slide the whole thing into a slightly bigger pot. Add media and that is it. To try to leverage the plant up and out of the pot may be a bit too rough.
I have cut away plastic pots on some very root bound Oncidiums and Cattleyas and this has worked pretty well for me. Just a suggestion Ted.

I have done the same as you, Nick with those type plants and pots. But this is in a gallon plastic pot I got at a show from Cal-Orchid. Just don't know if I should disturb it at all. It may be like my Psychopsis and pout for a year or two if disturbed. It is a terrestrial, so I don't have roots growing all over the place. And it is by far my largest orchid. Since it has new growth starting I think I will take Ursula's advice and leave it alone. If it ain't broke, don't fix it is one of my mantra's at the shop. Thanx to both of you.

Hey, good luck with whatever you decide!
