Repotting oncidium , should I split or combine them?

[Greenpots]

Hi guys,

I need to repot this oncidium and turn out there are 3 of them. After clean up,
1 look good with new shoot,
1 look good with new shoot but loosing leaf
1 not look good and loosing new shoot.

What do think I should do?

Thank you and have a great weekend guys

Since you've divided them already, I'd repot all of them... and if they survive, I would offer some.

They were packed and planted like that. If I comine them, what pot size will be ideal?

[Orchid Whisperer]

Definitely repot each separately, smallish pots, medium or fine bark. There is no benefit at all potting them together

I agree with OW. If they grow as expected in two years you may end up with a plant 3 times bigger.
If you combine them in a single pot I suspect you would need to repot them after one year, so...

Thank you all great inputs.
Here they are. Will see how they will turn out.

Although sphagnum would not be my first choice (holds more water than I care for), you may be able to make it work if you are careful. Don't water until you are seeing very little condensation through the clear plastic. This will require a lot of discipline, the tendency for most people is to overwater.

I would remove a little sphagnum from the top of the pot so that the bases of the pseudobulbs and rhizomes connecting the pseudobulbs are not covered. This will reduce the chance of rotting pseudobulbs.

What kind of medium did you used?

[Greenpots]

I use orchid mix from Homedepot and mix with spag moss.

I don't know the components of that mix. Can you specify?
