Repotted Brassia (Oncydium) with few roots left

[Maria José]

hello ,
I am quite new to orchids. I have just been growing Phalaenopsis for a year now. I keep all orchids indoors as I live in Dublin and the weather is cool in general. Last summer I got this Oncydium 'Brassia".

It was in a small grey pot, and two weeks ago I decided to repot, it. I put it into a bit bigger, transparent pot, with holes on the sides. Next, I got rid of all the dead roots and I was left with just a few ones.
I put it into a mix media (medium sized bark and bits of red clay) to which I added Spagnum moss. I read that this material would help with root development. I probably overwatered it and it happened to be raining a lot outside, so the plant got some spores growing on the roots. I had to repot it again, got rid of the Spagnum moss and added a tiny bit of perlite to it. My question is: is trying to anchor the plant with skewers enough? should I put it back into the small pot? The plant looks healthy to me. Regards,
