I got this dracaena over a month ago and it was doing well up until this week. This plant stays in an office with just fluorescent lights and is watered once a week. Last week it started getting some new growth up top, but I started to notice some of the leaves were browning. It was mainly the bottom ones so I thought nothing of it.
However this week, more and more leaves started falling off daily and today the center part (with the new growth) just fell off! What am I doing wrong? How can I save my plant?
