FLOUR TO HELP THE FLOWERS

When treating blackspot organically, there’s the oldfashioned method of using cornflour. It’s so cheap and easy to do and as you can see by my roses, it works. At the end of winter, just before the roses start to come into growth, sprinkle cornflour on all the ground underneath the roses and then cover that with some old compost. Sometimes if ever there’s a light breakout I repeat the process later in the year and that does the trick.
