I've got a border which is full of very large verbascum olypicum.

Trouble is, all the lower leaves are starting to get white spots which look
like some kind of mould.

A few weeks ago a borage in the same spot had this happen and I destroyed
it.

Do I need to destroy all the verbascum? Should I put anything in its place
or leave the area for a bit?

Arse!
