4. Care and Handling Tips
Proper care is essential for maximizing the vase life of dahlias.

Keep dahlias in a cool, dark environment at 40–50°F (4–10°C).
Avoid refrigerating with ethylene-producing fruits like apples or bananas.
c. Vase Life
Dahlias typically last 4–6 days in a vase.
Change water daily and re-trim stems to extend longevity.
