Cymbidium ensifolium blooming and repotting questions

[Dulcinea]

Hi everyone! I love scented orchids and I have a few Chinese cymbidiums. They haven’t been blooming much for me for several years. Yesterday I found to my surprise a cymbidium Tie Gu Shui Jing in bloom. Right now they’re outside in their summerhouse in partial shade. More than half shade. Our temps have been in the 90°’s most of the time for several weeks. Watering once or twice a week unless it rains.

In winter they grow in my plant shed under Florescent lights but a bit off to the side. Temps during the day 65°+ as sun comes in through a south slanting skylight. At night the temp drops to 55°. (A choice I opted for hoping to bloom cats, phals, brassavola and other miscellaneous other orchids. I keep the humidity as high as I can by spraying the cement floor every day. Most are fed weekly with U of M orchid food.

Most of my Chinese cymbidiums don’t flower under these conditions. They did flower years ago when I had a couple I kept in the house all year about 3' from south facing windows.

What should/could I do to get blooms?

My second question is what part if any should I cut off of this plant when I repot? It was repotted early this spring. I was unable to get it lower in the pot because of the difference in the height of the pseudobulbs.
