Hi, I have a ~4 month old Flame tree Bonsai. It seemed to be doing very well up until a week ago. The lower large leaves have fallen off but the rest of the tree looks ok? Is it normal for those bottom leaves to fall off? The attached picture shows one of the leaves in question before it fell off, the other fell off a few days later.

Thanks,
Walks

Hello...

That's pretty common to a Deciduous tree when climate starts to cool down, I don't know where you live, but here Flame trees shed 100% of their leafs...

And I can't see any photo btw.
