I've been taking care of this oncidium for few years and it's starting to grow at the very edge of the pot. Is it time to repot it in a bigger container? If so, when would be a good time? Another question that I have is; what can I do to keep older bulbs from dropping their leaves?
It was in a smaller container when I bought it from traders joe. When it outgrew it I split it in two and put it in it's current pot.
