When to cut spike on Oncidium?

Adlemsi,

I'm going to defer this question to someone that grows in your area and also uses s/h. I grow my plants pretty much out doors all year long, and I do not use s/h.

Having said that, I do most of my re-potting in the spring, as it is the natural time for my plants to really kick start their growing into full gear.
