hi, I’ve had this dragon plant for a month, and suddenly all of the leaves from the shorter stem are dropping off. It went from healthy to no leaves in 2 or 3 days. Can anyone advise what to do? I have been watering it pretty infrequently (every 10-14 days or so), and it doesn’t get direct sunlight. I’ve made sure the soil is dry before watering again. The label on the plant says it needs minimal water and shade.
