Thanks for sharing! I have multiple citrus plants, both indoors and out (in pots), and I've never had most of the leaves fall off any one of them, I was surprised when you said that. At this time of year (Christmas), the plants with fruit are ripe or almost ripe, and all of them seem to like the cool weather by growing.
Do you fertilize your citrus?
I'm glad to see how it turned out with your pruning. I intend to trim several of my plants around the beginning of spring.
