Repotting oncidium , should I split or combine them?
 

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?

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.

What kind of medium did you used?

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

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

This one media mix with spag moss
