I put my juniper into a small wooden box as a pot. I was looking at it today and noticed a white mold growing on the bottom of the box. Any ideas of what it could be? Is it harmful to my bonsai?
maybe we could look into it further if you could post a picture of it. If it's just on the pot, there is a chance it may have not harmed the plant. I think it would be better to remove it.
