Aphids are common garden pests that are particularly attracted to roses. Aphids congregate in large clusters, especially on young buds, and spoil the aesthetic value of a rose plant. They can weaken buds and stunt foliage growth. You can knock small aphid infestations off a rose plant with a strong spray from the hose. Larger infestations may require the use of insecticidal soap, which is easy to make with ingredients found in your kitchen.
Combine the vegetable oil, dishwashing liquid and water, and pour the solution into a spray bottle or tank sprayer.
Saturate the infested parts of the rose plant, including the undersides of the leaves.
Use the garden hose to wash the insecticidal soap off the rose plant after three hours has passed.
