Brown spot on 45 geraniums

[Supersimkin2]

Which comprise almost all my plants. I’ve de-leafed the affected plants 🪴 and got rid of the dodgy bits and sprayed with anti-fungus.

Is brown spot curable? Panicking cos it’s so humid here (London) and I can’t face replacing everything.

Help!

Do you mean herbacious perennial geraniums or annual pelargoniums? The annual ones dont always survive winter ( although they can if sheltered) and the perennial ones may be dying back for winter but will come back in the spring?

Perennials- they’ve all got rust.

I would cut back now and they will probably come back next year ok. Good luck!

Tidy up the clippings and bin or burn them, don't compost them.
