1. The oncidium was so rootbound when I bought it, that it was too big for the one size up pot. & the roots were cramped even after repotting it, they had no room to grow, or breath.
2. I had two clear containers the same size.
3. One psuedobulb was growing in a different direction.
4. I decided I wanted 2 leave one of them with my mom. & have two plants, the plant had just stopped flowering right before I bought it.
