Black spots on leaves - Scabiosa
I have two scabiosa in pots. I planted them last year. One ended up with powdery mildew. I cut it right back and both pots have spent the winter in a plastic cloche. The plant that had powdery mildew is a looking a bit sad - although it has sprouted new growth. The other is looking greener, but has a few leaves with black spots. I have started to feed them and put them in a sunny spot. Is black spot and powdery mildew the end of the road for these plants or will they survive another year in their pots?
