About a month and a half ago, I got a baby titan arum from a greenhouse I work at, and it's been healthy and happy up until about a week ago. The leaves are not as green or perky as they used to be, and it's growth pretty much plateaued at a little over 2 ft. I took a look at the tuber today and the roots look white and happy. My question is, is it going dormant, or is it under watered? I've been consistently watering it a couple times a week, or when the soil is dry, and recently it's been dry more often than not. I don't know for sure, but I believe it's been growing since about Christmas time, but it could be longer. This would be it's first dormancy, the tuber is still pretty small. Any suggestions?
