Hi I re-potted my Chinese myrtle bonsai about a month ago as the pot it originally came in had smashed and it’s started dying with the leaves browning and falling off. I only got it in August so I’ve not had it long and it was probably too early to repot but I had no choice. I used bonsai focus re-potting soil and what remained of the original soil and made sure it was moist rather than drenched. There’s no sign of root rot or anything I don’t know why it’s dying. I thought it was lighting at first it nearing winter in the uk but it has been next to a window so has had plenty of daylight. I don’t really know what to do to revive it. Any advice ?
