I have a very tall potted brugmansia, over 6 feet. I moved it indoors into my sunroom, but now it has lost all the flowers and leaves and only the very tall stalk with the Y remains. Do I cut it back or leave it? The previous years I have cut it all the way down and I never get flowers in the summer, not until right before the outdoor growing season ends here in Minnesota. Is that wrong to cut it that far back?

These plants bloom on new wood. Cutting them down that far inhibits blooming. Generally, the best time for pruning is spring since blooms usually begin appearing within a month or so following pruning.
