I have a small, 6 year old carmona/Fukien tea tree. Two months ago it lost some leaves from a heatwave but it has been recovering recently.
However, I noticed that some black spots on the leaves, which have also been causing the leaves to crack mildly, have been spreading. Two leaves had these cracks since I bought the tree last year but now they are appearing on more. Most of the leaves seem to be older.
Can anyone help me fix this problem? Thank you
