My Oncidiums wont flower !

[Maua]

I'm in New Zealand and have five Oncidiums but cant get them to flower. All appear heathy and start new shoots every year. I've tried in various situations but still no success. At present they are in sofused bright light, kept watered (we are in summer right now), mod temps and have good air circulation. Any clues to persuade them to flower ????

You'll have to let us know what plant it is exactly.
There are many different species and hybrids in the oncidium family.

Many have similar culture requirment, but not all.

Also how do you fertilize them and with what?

Yes, a little bit more info can be helpful. Depends on the Oncs you have, and if/how often you fertilize, as mentioned. What do you mean by bright light? Oncs can take a few hours of direct sun. Early or late in the day is better, when there's less chance of burning the plants. Mine (all hybrids except for one) bloom, and get enough sun in spring through fall for the plants to be a light green, and some bulbs are a bit yellow even.

If growing well, but not blooming, they may need more light. How does the foliage look? Should be fairly upright; not floppy.

Some Onc. intergenerics (those taking a lot after Odontoglossum) MAY want to be slightly cool.

Welcome to OrchidBoard

I've not worked out Oncidiums myself yet, so can't really advise, but I agree with others that there are lots of different Oncidiums so knowing more about what you have would help. Pictures help if you don't know the details, but you need 5 posts to do that.
