Need help with Ascf. Twinkle Pololei Orange

[Raqsharqi]

I got this over the summer with no growing instructions. I asked the grower to send me some information by email, and never got an answer. I don't know if I am supposed to put it on a winter rest plan, stick it in bright light, sing to it at night, or whatever else will make it grow. I think I put it in light that was too bright, or it didn't like the cold snap we had, because the leaves show damage. I'd really like some help with this before I kill it!
