A Green, Non-Toxic Solution To Keep Aphids Away from Edible Garden Plants?

Good Question

Pin it button big

Q:I tried searching your site and sister sites for green suggestions about how to keep aphids away from edible garden plants (like herbs, tomatoes, etc.). Was this topic ever covered here? If so, may I please have someone help direct me to this post? If not, can we please have a post or a reader forum covering this topic? Any help would be appreciated.

Editor: Ahn, we've written a few posts about how ladybugs are an aphid's worst enemy (Ladybugs and Your Garden and Pest Control: Ladybugs 101). Also, water, vinegar and dish soap are said to also be effective deterrents. You can also do some companion planting of 'sacrificial plants,' like nasturitiums or marigolds to attract aphids away from your vegetables. A reader in this comment thread swears by insecticidal soap to get rid of the aphids on her tomato plants.

Readers, other suggestions?
