Fukien Tea Bonsai Leaves Drooping

The humidity tray provides a small bubble of moisture around the tree to keep the tree from drying out.
Fukien tea bonsai leaves drooping. My fukien teas usually drop leaves yearly iirc but they are replaced fairly quickly almost as they drop. When night time temperatures drop below 45 degrees we suggest that you place the tree on a windowsill or on a table in front of one. I also know that once you let them dry out totally to the point that the leaves wilt those leaves will most likely drop but again will be replaced quickly. Fukien tea trees require a large amount of humidity and are traditionally placed in a humidity tray.
1 why are the leaves falling off my bonsai tree. Overwatering is a common reason when the indoor bonsai is planted in poor soil that retains too much water. The fukien tea bonsai must be kept moderately moist and will shrivel easily or simply stop growing if the root ball is permitted to dry out completely. It is an indoor plant with no insect infestation.
The leaves are all turning brown and dropping off one of the branches has no leaves left at all. It is a fukien tea well watered and kept in a shady place. The ideal indoor location is on a window sill facing south. A few months of overwatering will lead to root rot only visible in the tree losing strength and dropping its leaves.
Most indoor bonsai species ficus carmona etc do not drop their leaves unless there is a problem.
