Help needed / repotting yes or no / alternative?

[Blueszz]

Once again I need your help :-)

I have two Oncidium's Sweet Sugar and a Colmanara Wildcat. All of them are producing new growths.

Question 1) is it normal for Oncidium Sweet Sugar to produce 2 new growth's from the same pseudo bulb? Just being curious. I'm almost sure the answer must be somewhere here on the forums but I can't find it :-)

Question 2) I think at least 1 of the plants needs to be repotted as the new growth might grow out of the pot. I've read that the right time for repotting is when new growths appear. But... the plants still have enough room in the pot and without digging in the bark I can't find actual root growth from the pseudo bulb that bloomed a few weeks ago. The new growth's still are tiny (but grow fast, oh boy!). Is it OK to wait until I see new root growth on the new pseudo bulbs if I need to repot the plant?

Question 3) I've the idea to make the pot a bit higher on one side of the pot, with a piece of firm plastic sheet, to guide the roots from the bulb that might grow out of the pot into the pot... would that work?

I prefer not to repot as the medium still looks great from both 'Sweet Sugar's' I would love to see their roots but for me that's not a reason to stress the plants.

Thanks again for you time and help!
