I got it from Costco about half a year ago and it hasn't had many problems in the time that I've had it- in fact, it has flowered about 5 or 6 times since I bought it. I had to leave it at my old house for about 3 weeks after heading off to my university's dorms and during that time my family did not water it or anything- it just remained outside during the hot and humid wave through Missouri. Now, the leaves towards the bottom have turned yellow and brown and the newer growth is somehow shriveling but squishy at the same time and the tips are turning brown. And yet, somehow, it is growing a new stalk of flowers. Is it overwatered? Underwatered? Something else? Am I overreacting? note: Some of the leaves have been broken due to traveling. I did my best to cushion them but some didn't make it and have been broken for a while.
