jrat,
!
Daisy and Tarev gave some great advice and it sounds like you are headed down the right track with what you are doing. I don't have any advice to offer as far as plant care, but I do hope it all works out. I will say, though, that I love the tree-like look to your plant. I know others say to cut it to get it to grow bushier (and I love bushier plants, too), but if you didn't cut it back, I don't think it would be a bad thing! It looks so pretty and exotic the way it is right now. Whatever you decide to do, though, I know it will be a pretty plant for you and I think its great that you've cared for your grandmother's plant so successfully.
