I’m trying to dial in the care for this Coast Live Oak, and right now I’ve noticed what looks like fungus.It reminds me of the pic from your article “How to tell when something is wrong with your bonsai” from last year. This seems to coincide with all the rain we’ve been getting lately in the Bay Area, at least that’s when I really started to notice it. Is this tree getting too much water leading to fungus? Is it even fungus? What would you prescribe for a remedy?
