Extremely root-bound oncidium

[desirue]

Hi everyone. I attempted to repot one of my orchids from my large Carmela's Orchids batch early last month. It is my "speckle spire snowflake" oncidium. I made the decision to repot even though it was in bloom because I could see that a couple of leaves were starting to pleat suggesting stress to the roots. I was watering regularly, so I was pretty sure it wasn't from lack of that. Anyway; it's a fairly large plant; lots of pseudobulbs and leaf growth. So much so, I can't even see to the bottom. Well, I took it out of the pot ... and the sheer amount of roots it had, lol. I have never seen such a root-packed orchid before. It was severe. I attempted for hours (not exaggerating) to try and massage and untangle them best I could. I could not get them all untangled. There was some moss tucked up in the middle that I tried my best to get out.

In order for me to have gotten it all though, I would've had to literally rip hundreds of good roots out. I went ahead and repotted in a bigger pot (I believe it is 6") and used repotme's oncidium mix.

Do you think it'll be okay in the new medium even though I couldn't get all of the old moss out? Do you think I should've sacrificed some good roots to fully get to the middle? It was so root-packed, I couldn't get a chopstick or skewer even half-way up to clear a space.

It's currently growing new leaves and an additional flower stem.

How often do you think I need to water? Do more roots signal the need for more watering? Any helps or tips are appreciated. This orchid is by far my biggest one. Thanks guys!
