Harvest Tips
Cut flowers when blooms are fully open or just opening for longest vase life (10-14 days). Cut in early morning when stems are hydrated. Remove lower leaves below waterline. For perennial blooms next year, allow some flowers to remain on plant for seed production or cut back after first frost. Divide plants every 2-3 years in spring for renewal.
Fun Facts
- 🌱 Chrysanthemums are the national flower of Japan, where they have been cultivated for over 2,500 years. In Japanese culture, different colored mums carry different meanings—red symbolizes love and deep emotion.
- 🌱 Mums contain pyrethrin, a natural insecticide that repels many garden pests. This property has made them valuable in organic gardening and even in some commercial pesticide formulations.
- 🌱 Autumn mums' blooming is triggered by decreasing day length rather than temperature. When days fall below 10-12 hours, buds form naturally, which is why they reliably flower in fall regardless of geographic location.
