South Florida. Photo of tree that I can't identify. It's been raining heavily for twelve hours and this white foam has appeared on the trunk, possibly due to water dripping. What is this foam?
I've lived with this tree for 2 years and have never seen it happen before. It is not there today now that it's dry. I observed a piece of bark overhanging the area, channeling water to drip infrequently at the top portion of the bubbles, likely creating them somehow. These do not appear to be eggs or a fungus. When I hit them with a stick, they pop. Has less the consistency of spittle bubbles; more like soap bubbles. I do not use soap or detergent on my trees.
