Routine root loss?

[(..._...)]

Hi everyone

I have a question; I already asked about whether others ever loose roots after buying new plants ...(whether I repot or not, I guess the new watering schedual may be incorrect for many orchids' roots). But I also find that with some of my orchids (especially Oncidium alliance plants), they loose most of their roots every time I repot. New, healthy roots grow back, and are nice and healthy for the following year.

Does anyone else have this problem?

Thanks!

Cam
