What I usually do Chris, if the plant shows it is still forming new leaves, then I continue watering, but not at the rate I do it in summer, where I water almost everyday. I scale down, maybe one thorough watering once a week, and making sure that water drains out properly.
But if it is already visibly dropping leaves, I start to leave it alone, and let it go into its dormant phase. Consider too the color of the trunk, I find if it is still very young and green, it needs a bit more watering, but if it has managed to make its trunk a harder bark cover during summer, it is already able to stash whatever it needs during dormancy time.
