I was gifted a Carmona tree just before Christmas last year from my brother, and haven't had any issues with it until I noticed today a strange white fluffy growth looking thing around the base (it doesn't seem to be on the trunk). I live in Scotland and the light at this time of year leaves much to be desired, however it has a well lit position on my desk in front of the window. I've been feeding it every two weeks and watering it daily as instructed with the care instructions it came with.
I've attached a photo to help figure out what it is - really hope it's nothing damaging! It does occasionally drop leaves but because almost all of the leaves are a strong dark green and are shiny/healthy looking I didn't think it was an issue. Did some googling and wondering if it might just be some kind of mineral deposits from the water?
Thanks, any help would be much appreciated!
