Wow! They're beautiful! You must have lots of patience for this hobby! I love bonsai! Had one as a gift sometime ago, it lasted for 3 years, finally it died. Recently I had one as a Mother's day gift, the Gardenia Bonsai. After a week leaves started to turn yellow, though, I followed the instruction not to water too much, only when the surface got dried. I put it outside, it got better, I think. Now, it has more green leaves than yellow. I really want to save this tree. Thank you for sharing photos of your beautiful trees.
