My roses are still growing hard here in Sussex, and because of the
dryness and heat we now have the dreaded aphids making a return
visit.
I don't want to use Rose Clear etc, and have heard that they do not
like soapy water. Is this true, and if so what sort of soap and what
strength of mixture is best? Will dilute washing up liquid do the
trick for instance?

Washing-up liquid is not soap.

But it does the trick.

That was posted by me as a result of a premature finger twitch. I had meant
to ask whether the deading of the aphids by soap/detergent is then purely as
a result of the wetting power of the liquid?
