Q: Why are these growing from the muscadine? First time this has happened. Plant is about 6 years old.
A: They are called aerial roots. I’ve noticed them many times on the muscadine vines at Callaway Gardens. They seem to be initiated by some sort of wound, most likely cold damage on the woody arm of the vine. I have never noticed them doing harm to the plant.
Sometimes they will grow long enough to root in the ground but I don’t remember ever seeing another grape vine develop from them.
They are nothing to worry about as far as I know.
