Aphids represent one of the most common and frustrating pests for roses. They are most active in Spring and so are their natural predators: lacewings, hoverflies and ladybirds.
The best plan of attack with aphids is to encourage their natural predators to thrive and let them keep the aphids under control. Using chemical pesticides will only kill both the aphids and their predators, which is counterproductive.
Try picking off or squashing the clusters of aphids around the flower buds and new growth, or squirt them away with a jet from a garden hose.
If their population swells beyond a manageable number, the basic nature of a mild household organic detergent makes it perfect for getting rid of them.
Dilute a few tablespoons of organic dish soap in a small bucket of lukewarm water and use a sponge or spray bottle to apply the mixture to plants where aphids have taken hold. |
