Grapes

Question

I have a dessert grape that has bee neglected and recently pruned back and retied to new framework. My friendly neighbour garden did the work and suggested the grape may have a disease and he showed me a cut stem with a stain, bluish purple going brown. Is he right?

Answer 1

Yes. This can be treated, easily with wettable sulfur and dolomitic lime. This will take out the infection, and repair the soil pH after this is done.
