Dahlia and Chrysanthemum Cut-Flower Care: Make Fall Blooms Last

Dahlias and mums—autumn's floral royalty—can grace indoor arrangements for over a week with proper post-harvest handling.

Cut at the Right Time

• Best: Early morning (cells turgid from night moisture)
• Second best: Late evening
• Minimizes shock; maximizes vase life

Cut Clean, Cut Smart

• Sharp, clean knife or shears—mash/tear = shortened life
• Angle cut (not straight) for faster water uptake
• Mums: cut at full maturity (except open-centered types—cut pre-full-open)
• Woody stems impair keeping quality
• Wilting-prone varieties: split stem base 4–5 in, or scrape outer skin

The Boiling Water Trick

Dip stem ends in boiling water ~1 minute. Then deep-cold-water soak (to just below flower head) for several hours before arranging. Dramatically improves longevity for both dahlias and mums.

Results

Properly handled, both last 7–10+ days indoors—letting you enjoy fall's finest flowers long after the garden fades.
