Quick Answer:
The floral cold chain is a temperature-controlled supply chain for transporting cut flowers and plants at 2°C to 8°C from harvest through delivery. It extends flower vase life by 40-60% by slowing respiration and preventing wilting.
Flower Temperature & Humidity Requirements
Why Is Cold Chain Critical for Flowers?
- ✓ Slows Respiration - Cold temperatures reduce metabolic activity, preserving energy reserves and extending freshness.
- ✓ Reduces Ethylene Production - Lower temperatures minimize ethylene gas which causes premature aging and petal drop.
- ✓ Prevents Bacterial Growth - Cold chain inhibits bacteria and fungi that cause stem rot and water contamination.
- ✓ Maintains Hydration - Combined with humidity control, cold chain prevents water loss and wilting.
- ✓ Extends Vase Life 40-60% - Proper cold chain can double the display life of cut flowers.

Frequently Asked Questions
What is the floral cold chain?
The floral cold chain is a temperature-controlled supply chain specifically designed for transporting cut flowers and plants. It maintains temperatures between 2°C and 8°C from harvest through transport to delivery, extending flower freshness and vase life by 40-60%.
What temperature should flowers be transported at?
Most cut flowers should be transported at 2°C to 8°C. Tropical flowers like orchids prefer 10°C to 15°C, while roses and lilies do best at 2°C to 4°C. Humidity should be maintained at 85-95%.
How long can flowers survive without cold chain?
In UAE's summer heat (40°C+), unrefrigerated flowers can wilt within 2-4 hours. With proper cold chain at 2-8°C, cut flowers can maintain quality for 5-7 days during transport and storage.
