I have a few primrose jasmine that have done well for a few years. this spring some of the leaves were truingvery light green/yellow. I found that the shoots had splits in the bark and developed bunches of hard nodules in the splits. They healthy looking shoots did not have this. However, about 30% of the shoots seem to be affected.
I live in Phoenix, AZ and the plants have weathered summers here quite well thus far. I am concerned that this may be a spreading disease. Does anyone know what it is and how to deal with it?
Thanks.
