My uncle Jacques in NSW is an avid gardener with some very beautiful roses. My mum was recently made privy to his tried and tested recipe that I thought I should share...
Mulch: Cow manure (I'm also told from another source that lucerne is a popular mulch too)
Pruning: Light pruning anytime after flowering. Hard pruning in mid-late August
Fertilise: Use 'Sudden Impact' August, November and March
Insects: Pyrethrum when required. You can also alternate with Pest Oil if necessary
Mildew/Black spot: Spray with 1 part full-cream milk/9 parts water
