Hi I just recently got a new bonsai (my first) for christmas and I was wondering if someone could give me some advice. I have a feeling I've been overwatering my bonsai tree cause recently theres been what appears to be mould growing on the surface of the compost. I'm worried cause I think it may end up affecting the pH of the soil or something killing my tree

I was thinking of allowing the soil to dry up a little possibly killing off the mould but that may also affect the tree! lmao Any advice would be really appreciated

Kthanksbai!
