I can’t remember when I last had an aphid attack. I think I just hosed them off with a jet of water. But, then, my “garden” has lots of “weeds” that bug predators like, and I have a mix of plants, rather than beds with monocultures, so I imagine those things play an important part. Also, plants that may be prone to aphids, like roses, have to be a bit tough to survive my Darwinian methods. So, maybe they are not as succulent to aphids as something like cucumbers and other veggies would be. I like the ‘Peppermint Fury’ idea, too.
