How Freezing Temperature effect fresh flowers
Fresh cut flowers bring beauty and vibrancy to any space, but their delicate nature makes them highly sensitive to environmental conditions. One of the biggest threats to their freshness and longevity is exposure to below-freezing temperatures. Understanding how cold affects flowers and the proactive steps florists take to safeguard them can help you appreciate the value and effort behind every bouquet.
How Below-Freezing Temperatures Affect Flowers
When temperatures dip below freezing (32°F or 0°C), the water inside the cells of flower petals and stems begins to freeze. This causes the ice crystals to expand, rupturing the cell walls and leading to irreversible damage. The result is often wilted, discolored, or mushy flowers that lose their aesthetic appeal and structural integrity. Some blooms, such as roses, lilies, and tulips, are particularly susceptible to cold damage due to their high water content.
In addition to physical damage, prolonged exposure to freezing temperatures can halt the metabolic processes that keep flowers vibrant. Even a short period in freezing conditions can cause certain flowers to become unusable for arrangements or displays.
Steps We Take to Protect Your Flowers
Professional florists take several precautions to ensure flowers stay fresh and undamaged during colder months:
- Temperature-Controlled Environments: Florists store flowers in carefully controlled environments. Refrigerators are set to an optimal range of 34°F to 38°F, which keeps flowers fresh without risking freezing. These coolers maintain consistent humidity levels to prevent dehydration.
- Insulated Packaging: When transporting flowers, especially during winter, florists use insulated wrapping materials. Layers of paper, plastic, or fabric provide a barrier against the cold, preventing direct exposure to freezing air.
- Heated Delivery Vehicles: Delivery vehicles equipped with heating systems ensure that flowers remain in a temperature-safe environment while in transit. This is especially crucial for long-distance deliveries or when delivering to outdoor events in cold weather.
- Timing and Planning: Florists often schedule deliveries during the warmest part of the day and avoid leaving flowers outside for extended periods. Proper coordination ensures minimal exposure to cold temperatures.
- Choosing Hardy Varieties: In colder climates, florists may opt for flower varieties that are more resistant to cold damage. While not immune, these flowers are better suited to withstand brief exposure to low temperatures.
- Customer Education: Florists advise customers on how to care for their flowers after purchase. For instance, they recommend bringing flowers indoors promptly and avoiding placement near drafty windows, unheated rooms, or outdoor areas.
What You Can Do as a Consumer
If you purchase fresh cut flowers during freezing weather, follow these tips to preserve their beauty:
- Transport Quickly: Minimize the time flowers are exposed to the cold. If possible, preheat your car before transporting them.
- Provide Proper Care: Once home, trim the stems and place the flowers in room-temperature water immediately. Keep them away from cold drafts or heat sources like radiators.
- Protect Outdoor Displays: If flowers are part of an outdoor event, use protective coverings and ensure they are exposed to the cold for as short a time as possible.
Conclusion
Below-freezing temperatures can pose significant challenges for fresh cut flowers, but with the expertise and preparation of professional florists, these challenges can be mitigated. By understanding the effects of cold weather and taking appropriate precautions, both florists and consumers can enjoy the beauty of fresh flowers year-round.
