grape vine help
 

Hi, I live in Melbourne; my grape vine has just started shooting and I would
like some advice on care to ensure the best grape yield please. The vine is
several years old and I prune it well every year but never have much success
with grapes. I was told a few years ago that I need to spray it with
sulpher at some stage, but not sure of the exact timing, I also struggle
each year to keep it free of caterpillars. Any advice would be more than
welcome.

Thanks!
