Conseils de culture
Chrysanthemums are short-day plants; use blackout curtains to induce flowering (14+ hours of darkness) or long-day lighting to delay flowering for scheduling.
Pinch growing tips 2-3 weeks after transplanting to promote branching for spray-type varieties; disbud for single-stem standards.
White rust (Puccinia horiana) is a quarantine disease in many countries — inspect incoming cuttings and maintain strict hygiene protocols.
