Two oncidium types?

[euplusia]

Very colourful hybrids. You made them bloom again, which is a great success.
In my experience they should be repotted annually in a medium fine bark mix. During summertime you can grow them intermediate to warm, with regular watering and diluted fertilizing. Don't forget a Ca/Mg-fertilizer. When the bulb is nearly completed in autumn, reduce watering and fertilizing by giving less water and a prolonged intervall. When days grow grey and short, provide maximum light.
Eventually you can grow them outside in summertime, the climate in the UK should be beneficial.
