My potted chrysanthemum has finished flowering. If planted outdoors will it re-flower next year?
Your mum is probably a florist chrysanthemum (mum), which probably won't survive the winter in areas colder than Zones 6 or 7. Even if it does survive, it probably won't flower again because florist chrysanthemums are late-flowering plants. Even hardy mums grown in pots for outdoor display may not live through the winter unless they have developed a strong root system first.
If you decide to try planting your mum outdoors, keep it well watered until the first frost and mulch with 4-6 inches of straw or other mulching material when the ground freezes.
Hardy mums can be distinguished from florist mums by their thick underground shoots, or stolons. If you want to grow these beautiful plants outdoors, choose some of the many hardy mums species and varieties that are readily available in nurseries.
