Powdery mildew on Stachys
Hi all, I've been growing Stachys 'Big Ears' for a year or so and this year it's had powdery mildew over pretty much all the leaves. Is it worth treating or would it keep coming back?
I was already a bit disappointed with it as I didn't realise it wouldn't flower when I bought it, and one of the selling points was that stachys in general seems to attract a lot of bees. So I'm on the cusp of pulling it up, but a 2nd opinion would help!
