touch and go if you do - if we have an Indian summer, they might, if we don't, they're done for this year. Mine are the same, looking long and stringy with brown leaves near the base, but I've left them alone.

many thanks I would have cut then and hope for another florish as they look so good in the potsand lots of colour

Well you can risk it if you want, you might get away with it, its only the first week of August. Welcome to GoY!

Use tomato feed as a liquid fertiliser ,if you dont already its good for flowers, as you prob know ,so more flowers might hide the leggyness.
