Admittedly I've been totally slack about watering them (like maybe every 10 days, but they're well mulched).
They're growing in a no dig garden - 30cm hay, 20cm compost, 10cm hay mulch - on a soil base. Companion planting is broad beans. They looked totally healthy until last week, then sick and horrible within days. They are kipflers, virus free - fresh from a catalogue this year.
Will I have to quarantine this bed for potatoes now? What about other solanaceae (tomatoes/ eggplants)? Is there anything I can plant to clean it up?
Should have kept the water up more, given them a chance to fight off whatever it is. I'm guessing a virus...?
