Keeping Nobiles rootbound?

[missann]

Ok, so I bought this great d. nobile from maui orchids for 8 bux, and I love love love it. I know that nobiles like to be root bound, but it came in a 3.5 inch pot, and it is top heavy, so I want to put it in a bigger pot. The pot is big enough that I can stick my index finger in on each side. I am afraid that is going to be too big though, and that it won't bloom if I have it potted in there.

Also, there are all these crazy roots that have started growing outside of the pot, and I would like to have them be inside of the new pot.

What to do? I have been thinking of wrapping the existing rootball in plastic (on the sides only, not the top or bottom) to simulate it being in it's former small pot. Then, I would like to place the whole thing in the larger pot and put potting media around the new roots, so they are nice and safe in the pot. Then, after it blooms in the spring, I can give it a proper repotting with new media etc. One more thing, in the pics of the plant with my finger in there, the root ball is moved all the way over into the corner of the pot, not sitting evenly in the middle, so it looks like I have a lot of room between the root ball and the pot.

I don't know how the orchid can tell if it's roots are in a little container, or in a pot with a lot of room around them. Or does it just mean to leave the tight rootball intact and not tease it out? I just keep reading to "not put it in a pot too big, or it won't flower.'
