white mucus on the branches of blueberries
Sorry this took so long. Things have been pretty strange the last few weeks.
The short answer is I do not know. I get a question about this every few years and have never found an answer. I have looked and asked and everyone else scratches their heads and says "I don't know" To my knowledge this does not harm the plant in any way. Please let me know if you see anything else.
Yes, there is no damage to plants from this.
