Rust

Wildlifelover

Evening,

I purchased some Campanula superba a few weeks ago and they’ve all developed rust. Is this something I’ve done or just bad luck?

Can the plants live with this or should I dispose of them all?

Thanks.

I think there's a specific type of rust that only affects campanula but l can't recall the name of it.
I would remove the affected foliage and maybe try something like a Fungus fighter or a sulphur dust.

@Wildflowerlover You say you purchased only a few weeks ago. I would contact the GC [if that is where you got them from] maybe the rest of the stock is affected and if so could they give a replacement but not from the same batch of plants?

Thanks. Pretty much the whole of every plant (x5) is affected. As a complete novice, not heard of those treatments - would you recommend them?

Yes, I got these from Crocus as they were on offer (I think they still are). I’ll send them an email and see what they say.

I did a bit of digging on the site and found this, it says the same thing and gives the name l couldn't remember  (Coleosporium)

I have used Fungus fighter on Michaelmas daisies to good effect.

Haven't used sulphur powder for a while as l found the spray easier.
