Talkback: Growing roses - rose diseases
in Talkback
Even on a drizzly day like today I go out in the garden and inspect my roses and take off and dispose of any leaves with blackspot on. I've never needed to spray in this garden for the 47 years I have been growing roses. My "Albertine","Queen Elizabeth, the Queen Mother", "Matisse", "Iceberg" and Bourbon roses are making a splendid, fragrant display as well as the ramblers I do not know the name of as they were in the garden when I came. But my favourites are the early ones, "Canary Bird" and the Banksian rose which never seem to have any disease.

This insect doesn't really do any harm, although any insect feeding on plant sap can introduce virus disease.
You can simply rub them away between your fingers, or blast off with a jet of soapy water.
A hedge of lavender near my home is covered with them, but within a month them will have gone.
