A couple of years ago I grew some Nasturtium , all started off well , but as the plants got larger they got smothered in black fly , I sprayed them but it didn't seem to help much , in the end pulled plants up as the back fly was starting to affect other plants . Are Nasturtium prone to flys ?

They certainly are! I just ignore the blackfly, but you could either spray with a soap solution or have a squishing campaign if you don't want to use insecticide because of its harmful effects on bees and other beneficial insects.

These plants are often grown near vegetables because the aphids will prefer the nasturtiums to the veggies, so have a protective effect. If you're going to use washing up liquid, make sure its an eco friendly one - ordinary liquid is as harmful as pesticides, if not more so.

Agree with other comments, have now given up on nasturtiums, much as I like them, find the constant blackfly too annoying, and you are right, they do spread to nearby plants.Now I plant pelargoniums where I want some reliable orange-y red colour, no problems there.
