Q.I Have An Indoor Potted Crown Of Thorns That Has Never Had Blooms. Any Suggestions.
I have had it about 6 years. I have repotted and pruned once. It sits at a window that gets the morning sun.

Usually a plant not flowering isn't getting enough light. Try moving it to a south or west facing window. You also can move these plants outdoors in the summer if you would like. Just be sure to bring it back in before the temperatures drop in the fall.
