Q.Sedum (stonecrop) Issue
In previous years this sedum spectabile (stonecrop) has been stunning. However, this year it hasn’t flower and seems to be ill. It has produced lots of flower heads but the flowers haven’t opened and have turned brown and dry. Large brown lesions on the leaves. Earlier in the year I suspected powdery mildew and treated for that, but it didn’t seem to help. We moved the sedum in spring from its usual spot using good planting technique, lots of drainage etc. It has been a very wet summer here in South Wales, UK though. Would like to know whether it will survive next year if cut back hard, or if it’s time to say goodbye to this plant. It’s in a central location in the garden and depressing to look at! Any advice greatly appreciated!

I would suspect the wet season for being the reason that it is dying. I would treat it with fungicides as early as possible, but take a few baby pups from it as well. You may want to take those inside and baby them. Treat them with fungicides often and keep a close eye on them.
