Thanks 11orchid126. I stopped fertilizing the end of August. I'm sure I won't have any problems with the temperature requirements and you have answered my own questions regarding the watering process over the winter.
I also found Yamamoto's site and there's a weath of valuable information. For those who would like to check it out, here's the link. Check out the care section. Hopefully, I'll get some blooms from my Oriental Smiles. Good luck with yours.
