Is Fairy Liquid safe to use on roses with greenfly?

Never tried it before and just want to use something that isn't harmful to anything other than the aphids.

No idea of the dilution either, I don't want the rose plants to look like they have just been pulled out of the dishwasher.

Other 'organic' solutions to the greenfly/aphids problem are most welcome. I only suggest Fairy Liquid as it's something that I have.

Thanks.

 

Perfect on all plants (and to get rid of ants). I just use a squirt in a normal bottle.

 

Thanks, I'll look into that.

 

or something like this Castile...

 

Fairy contains quite a lot of harsh chemicals to remove burned-on food etc, so I use shower gel rather then Fairy.
Whichever you use you only need about 4-5 little drops in 1/2 litre of water.
It's not the detergent that does the damage to the aphids. The detergent just breaks the surface tension of plain water which is what helps shift them.
