I've had this poinsettia for almost a year now. Adopted it from walmart, and for a really long time it was doing amazing! It tripled in size since I bought it, and it's never had any issues at all... until I moved into my new apartment.
Ever since I moved, the leaves have been turning brown and it's dropping them like crazy; even the ones that seem really healthy are falling off. At first I thought it was because it was situated near a heater vent, but its condition hasn't improved after moving it to a less dry spot a few weeks ago. I'm beginning to worry because even the new leaves are dying as soon as they come out. But it's not wilted, so I don't think underwatering or overwatering is the issue? I water it whenever the soil feels dry.
The only difference that I thought could factor in between my apartment and old residence is that I now have to use city water (which is relatively clean, given how dirty city water can be) but I used to have well water. Should I start giving it bottled water?
I've looked into poinsettia issues but I can't pinpoint what's going on with it because it fits more than one criteria, but maybe someone who knows plant illnesses better can help me?
[yes it's very oddly shaped which is normal, i've never pruned it x) ]
