How do I identify and treat aphids on roses?
Aphids (greenfly or blackfly) are small, soft-bodied insects, often green, black, or grey, found in clusters on new shoots, buds, and the undersides of leaves. They suck sap, causing distorted growth and a sticky honeydew. Treat by blasting them off with a strong jet of water, squishing them by hand, encouraging natural predators (ladybirds, lacewings), or using organic insecticidal soap for heavy infestations. Repeat treatments may be necessary.
