Please, could you let me know if the leaves changed color on your Chinese Elm bonsai just before they started to drop? Did they go spotty or black at the tips or? This is a perfectly normal seasonal change in deciduous outdoor bonsai. The indoor bonsai may also lose some of their older leaves. This is particularly obvious in the Chinese Elms.
The older leaves turn yellow and then drop off. The Juniper is an evergreen, while the Elm is a deciduous tree that drops its leaves (or at least part of it) during autumn and winter. Watering too often, while the tree is planted in a soil mixture that retains too much water, will lead to root-rot and the tree dropping its leaves. I bought a Chinese Elm Bonsai while vacationing in Florida. My problem is that this Bonsai is dropping leaves constantly. There is also a lot of new growth on the tree, but even some of the new little leaves turn yellow.
Hi everyone! Sorry in advance about the long post, and I hope the images aren’t too big. I received Chinese Elm as a gift last June. When grown under ideal conditions, the tree is evergreen. However, in a less-than-ideal environment, it will become deciduous and drop its leaves. The tree grows rapidly and is adorned with glossy green leaves of heavy substance. It makes an easy-care and supremely eye-catching bonsai specimen.
