Answer: Some gardeners report that planting garlic, or even chives which are also in the onion family, will repel aphids and can thus help control an aphid problem on nearby roses or other plants. For this reason they may plant the onions at the foot of the rose bushes or in between or along side another aphid-prone plant such as peas. If you would like to try it, simply plant them in close proximity to the plant you would like to protect and see if it works for you. Other simple aphid controls would also include spraying them off/ knocking them down with a strong surge of water from the hose and spraying with insecticidal soap according to the label instructions.
