Planting and care
There has to be a clue in the fact that it is apparently spreading up the line, rather than all the plants ailing at once. My first instinct was root knot nematode, but most sources say that Gelsemium is practically immune to them.

- Prune Carolina Jasmine immediately after flowering, removing dead or broken branches and shaping the plant.

or from stem cuttings taken from established new growth in the spring
