Hello everyone,
I need urgent help as I don't know what to do.. my bonsai is an oriental tea tree (Carmona microphylla) which I have since September. It was fine until the winter when it started to look a bit tired but I thought it was just because of the cold and short days. Indeed at the beginning of spring it started producing new leaves (probably around end of April) and I thought it would be just fine, but in the recent weeks it's just been getting worse, with the leaves turning brown at the tip and drying out, and within a week or so it started loosing all its leaves. I believe I might have overwatered it at some point, but now I suspect there might also be some kind of fungal infection (there seems to be some tiny white spots on some of the leaves.
Please see pictures attached.
I just bought some bonsai soil mix to try and repot it after checking the roots, and hope for the best. Is that the right thing to do?
I sincerely hope it is still time to save it.. i checked the bark by making a tiny cut and it was still green inside.
Thank you all for your help,
Marie
