I don't want to use insecticide as i dont want chemicals on the garden and i have a 20m old daughter, also the rose is planted in a bed where i have planted lots of herbs i intend to eat. I know about the lady birds but not sure how i attract them. I have planted some marigolds uner it today, also have corriander which apparently repels greenfly. My mothers rose has been decimated by the little bastards and i like my rose i do!
