I've just become the proud owner of a beautiful Chinese Elm bonsai that traveled all the way from California to my home in the mountains of North Carolina. I'm very new to caring for a bonsai of any type, and I'm a bit worried about the yellowing leaves on my tree that fall off at the touch. I've been watering it a little bit in the evening as the pamphlet said, I pruned a little bit to get rid of some scraggly branches, I keep it in direct sunlight in the mornings and filtered light in the afternoon, I set it outside when it's warm, and I play music for it here and there. I'm not entirely sure if it's just in shock after traveling six days by mail (it was very nicely packaged, but I can imagine that would be traumatizing for any plant), or if there's something else that I'm doing wrong. I'm worried that the soil isn't draining properly, or if I'm watering it too much, but then again, I have no idea.
Any advice would be very much appreciated!
