How to Get Rid of Aphids on My Rose Bush

By Stephanie Green ; Updated September 21, 2017

While they are tiny in size, aphids can be a major problem for rose bushes. Found most active in May and early June, the pest thrives on tender plants and its juices. Because they multiply quickly, gardeners must act just as fast with one of many methods that effectively rid aphids from a rose bush.

Use a natural control method. Spray infested leaves with a stream of water from the garden hose to wash the aphids away. Wear gloves and physically remove aphids from a rose bush when there is a small population.

Use an insecticidal soap as an economical way to remove the pests. Mix a 1- to 2-percent solution with water in a clean, 1-gallon spray bottle. Spray the plant with water from the garden hose. Follow with a thorough spraying of the insecticidal soap. Wait 30 minutes and spray the plant with water again. (This will prevent damaging leaf tissue.) Reapply the water and soap at least every other day until the infestation is reduced.

Get rid of aphids with a chemical treatment. Apply a chemical spray readily available at nurseries or garden centers. Rotate treatment from insecticidal soap (in step 2) to a chemical spray to prevent the aphids from resisting one form of treatment and re-colonizing the rose bush..

Make a homemade solution to get rid of aphids. Mix and apply a homemade rhubarb spray. Chop five or six rhubarb leaves and add to 1 quart of water. Boil for 30 minutes. Add one squirt of dish washing liquid to the mixture. Strain the mixture through a sieve, and then allow it to cool. Pour it into a spray bottle. Spray generously onto infected leaves or canes.
