I am a new bonsai owner. I got this plant recently (it is a Serissa Serissoides - Snow Rose?) but it is 8 years old and has been in training for 5. It is my first bonsai. Anyway, i've been watering him and spraying the leaves. I haven't soaked the pot yet. I've had him for about 2 months. The reason i am posting is that one of his branches seems to be doing really well, with green leaves etc but the other branch has no leaves. It did have leaves but they have since shriveled up and fallen off. I know this plant is deciduous, and have been told the leaves will fall off and grow back, but it seems odd that the same branch attached to one trunk and in the same conditions would be in such different states. Is it something I am doing? Is it just how this plant is?

Sorry, I couldn't figure out how to directly add a picture but here is a link.
