As they flower prolifically, dianthus, especially the carnation types like good well composted soil(really good drainage though), and a high potassium feed to keep them going. But they're not very long lived, so it could be yours are ready to finish. Maybe take some cuttings now, just in case.

How long lived are they, stevee!

They are only 2-3 months old

stevee6 I have quite a big bed of dianthus that are just finishing flowering, if I prune them back down lower will they sprout away again! . Was kind of hoping they would cause it gets expensive replacing annuals often. TIA

I cant promise you yours will survive but here in Chch I cut mine back after the flowering is finished , feed and water and away they go again , this is their 2nd year now too!

Varied - I've got a Mrs Sinkins which is several years old, but bought a hybrid last year which flowered then promptly died. They're really easy to strike cuttings from though.

Cut back the finished flowers and then you should have a rather nice silverygrey hummock until next spring/summer when they flower again. As earlier, take a few cuttings though, just in case.

I will do that thank you.

Have found that they really like very sunny spots to grow in. Part sun/shade they don't flower very well. Just making this point, as Isaw some in a garden and she was saying they were a disappointment to her. Told her to shift them and they are great now.

Mine are in a very sunny spot, in fact, I did wonder whether it may be too sunny and that was the problem.I have taken some cuttings anyway so hopefully they will grow for next season if the others don't pick up - thanks

Sunny spot, great drainage - they love both. My best ones are on sand, and doing well.
