Q.Yucca
My indoor yucca plant, which has a trunk, loses leaves every winter. They are usually from the bottom of the growth of leaves and they droop, then go yellow and die. It is regularly fed in growing season and is not pot bound. I do water every couple of weeks in winter so as not to over water. It is moist at the moment and watered a week ago and leaves are starting to die again like last year.

Most likely you are watering it too much. Wait until the soil in the pot is completely dry before watering. Also, in winter plants need less water...usually only once a month.
