kniphofia said:Your roses have greenfly or aphids which is normal for this time of year. Resist the urge to spray or poison, ladybird larvae and nesting birds are looking for food at the moment and will clear the aphids.

GardenDreaming said:I am struggling with the same problems in my rooftop garden. Most of my plants look healthy, but recently a few of my plants, especially my roses, seem to be hit with thrips, aphids and perhaps something else. The leaves have been yellowing, falling off and growing-in misshapen. I am heartbroken because it looks like I am about to lose the two baby rose plants I just bought from Northland Rosarium. If the plant has lost many leaves, is there anything I can do to save it without using insecticide? I already tried a mixture of soap, water and veg oil, and that doesn't seem to have slowed the bugs down for more than a day.

I'd rather not....
The important thing to remember about aphids... they are self-limiting.
The population always crashes after spiking.
Some people suggest giving that crash a hand by knocking some aphids in a blender... blend them up... spray the rest with that mixture... the idea is to hurry a population crash by spreading aphid equivalent 'covid'.
