My Sherry Babies spiked and flowered last year. This year, one spiked and flowered. It sent up another spike now almost 4' but no blooms showing. The second is doing the same. In east window with ample light. What is the issue? How solve?
Likely the issue is lack of patience on your part.
From start of spike to blooms takes around four months on most of my Onc.... some even longer. Sounds like they're doing just fine to me.
Welcome to Orchid Board! And you may want to have an admin or someone with more expertise than I tell you how to change your name from your email to something more generic. You don't really want your "real" email addy floating around on a forum.
Agree that you really don't want your ID to be your email!
Request an ID change ASAP, it could take admins months to change.
Re: your Oncidiums, even though you think you are getting enough light, your bloom problem could still indicate that the light is below optimal. That often leads to spikes with few blooms or delayed blooming.
