Dividing backbulbs

[Dollythehun]

I never watch YouTube! However, my attention was called to Roger's Orchids. He was discussing the Oncidium tribe. I've looked for the video and can't find the link.

Anyway, Roger was inspecting his Twinkles, which had exploded in growth. Now since there were lots of leafless backbulbs, Roger said he was going to divide them. He said that for the health of the plant and asthetics, it was wise to divide them.

Mine have done the same thing, exploded with growth, bloomed their heads off, and now have lots of leafless bulbs. I'm thinking he's right. Much like an ornamental grass grows out and has to be divided to get rid of the "bald" center, once divided, the newer divisions usually take right off. I'd like to hear your thoughts?
