I'm not sure what you're doing whenyou say you're deadheading - the point of this procedure is to stop the fertilised flower from producing a seed pod, so that the plant continues to flower. If you're not taking off the whole flower and its incipient seedpod, then it's a pointless exercise. Nip of any seedpods you can see now, unless you want to allow one or two to ripen so you can collect and sow the seed next year.

If the leaves are actually dead you can take them off, but it sounds as if your plants could do with extra watering.

You wait until the flower has died though.

very good advise, its the first time Ive had these and unusually there isn't very much info about them on the net, so i will do them again and take off the seed pods as well as the limp foliage, thanks again both of you

Have you kept them well watered? If not try watering before finally taking off the limp leaves. I would leave them alone if they were mine.

So would I, unless they were actually completely brown and crispy - the leaves I mean, not the seedpods.

I think we have all been feeling rather brown and crispy this week...

okey dokee, will just take off the seed pods,
