Brassia roquebrune 'spider' dry aerial roots: repot or not?

[Piao Liang]

I have a Brassia bought in August 2015. Somebody in the forum told me to repot it but I was afraid from bad experiences repotting anything other than Phals. It has massive new growth but many aerial roots dried as it is dry in Marseille. But I followed instructions for watering with the skewer method and weighing and I think it had the right amount of water judging from its growth. However, it has become very heavy and it hangs forward. It has started new root growth. My question is, should I repot it or should I leave it alone to recover its roots? I am showing a picture of when I got it and 2 in its present state. Many thanks!

These like to stay slightly damp. So I would want to re-pot in a slightly larger pot and set it in there so that some of those roots are buried. You can maybe get it sitting straighter and then stake it. It looks like very large chunky media for such fine roots. I would also want to know for sure that there isn't a wet mass of moss in the centre. With new roots started, now is the time.

I have been moving to a bit chunkier medium for some of my Oncidiums and they seem to do well. I used to use fine bark and moss. But just make sure the roots are healthy in the pot. That looks like large orchiata which can dry out pretty fast. Make sure the pot has good drainage holes too.
