Last year, I visited a local orchid nursery (Orchids by Hausermann in Villa Park, IL) on the occasion of their annual open house and sale. Among my purchases was a beautiful yellow Cymbidium. I had owned two Cymbidiums in the past, but had to discard them due to a scale infestation. (I have learned, the hard way, that it is best to get rid of plants with scale. This doesn't mean I always do; as a matter of fact, I have rescued both my much loved Monstera deliciosa and my ZZ plant from scale, but it wasn't easy.)

So I bought this plant wondering if, after the blooms faded, I'd ever see it bloom again. Orchids are finicky, I thought. I haven't been the most diligent of plant caretakers, especially these past few years. But the care sheet made it seem simple enough: Let the plant spend the summer outdoors in dappled light. The cooler night temperatures as fall approached would encourage rebloom.
Did I do that? No, I didn't. I left the plant in my sunroom. I repotted it after the flowers died. I used the special Cymbidium mix I bought for it, but I didn't put it outdoors. I fed it a couple of times when I remembered. But I kept it indoors. My sunroom does undergo a natural cool down at night. In the cool months, I keep the heater set at 60 degrees Fahrenheit. During the day, the sun warms the room to at least 70 degrees, and oftimes warmer.

I have to admit that I don't know if the plant bloomed again because it liked my conditions, or because of the professional care it received previously. Next year will be the test. I plan to repot it again after the blooms fade. I'm not sure when that will be. The plant started blooming in January, and is still going strong in March.
