Watch out for
Smut fungus: Remove and dispose of infected flower heads to prevent spread, though damage is usually minor.
Slugs and snails: Use beer traps, copper tape, or hand-pick at dusk; keep areas weed-free to reduce habitat.
Vine weevil: Check roots when buying potted plants and apply biological nematodes to soil in autumn.
Waterlogging: Plant in well-drained soil and avoid heavy clay sites without improving drainage first.
