I have one Oncidium and one Vanilla Planiflora in my home, and I'm hoping I manage to keep them alive and get them to flower! The Oncidium has flowered previously but then had some die-back, due I think to watering issues. I'm now trying to get a little more organized about my approach!
Any beginner growing tips for these two varieties is much appreciated!
Here is a link to a page that has many care sheets for orchids, including oncidiums. The culture sheets are the same ones used by the American Orchid Society, and are used on this site with permission:
