I have two different varieties of this orchid that I have seen classified different ways. They are great orchids as once they grow a flower stalk, they will continue to pop out great flowers for years. The two that I have, Oncidium Mariposa ‘Magestic’ and Oncidium Mendenhall ‘Monarch’, both have two flower stalks and a lot of new pseudobulb growth and I think finally need to be repotted. The place I live in is very cool in the winter, any recommendations on potting materials? I was thinking about clay and sphagnum moss or a phaleanopsis mix I got from repotme.com that is a mix of sphagnum moss and materials. I also do not want to sacrifice the flower stalks that have just finally matured.
