Default When to cut Oncidium Flower spike?

Hi, this is just a quick question I have an Oncidium multi-hybrid plant. Itís flowers are starting to drop so Iím wondering when should I cut the flower spike? A lot of people say cut it when itís brown after the sap is ďrecycledĒ or some people say it doesnít really matter and you should cut it immediately to promote new growth. Opinions?

Yes, the plant resorbs those nutrients.

Yes, it looks like hell while that happens.

If you are OK with leaving it, leave it. If not, chop it off - it's not providing THAT much to the plant. Some plants (phals, for example) can rebloom from the same spike, so I'm more likely to leave it. Oncids? Nope.

When to cut Oncidium Flower spike?

I have always cut my oncidium spikes once they start to fade. Most Oncidiums put so much energy into producing a substantial spike I just feel that when the flowers begin to fail the plant is saying "i am tired and had enough". I cannot see how a plant can suddenly decide that it is time for no more growth so I'll suck goodness what goodness is left for another time. It seems more likely to me that the plant just decides to hut down goodness flow to the spike. Now leaves are quite different in taking in energy. Some people even cut flower spikes off very early from Oncidiinae especially on young plants to conserve energy. I guess either way you are not going to make much difference on a mature plant. Again, some people hold that some species oncidiinae might even exert so much energy that they flower themselves to death and the pseudobulbs just shrink away.
