When it comes to taking care of flowers, many people are left wondering whether they should refrigerate them or not. This is a common question that has sparked a lot of debate among florists, gardeners, and flower enthusiasts. Refrigerating flowers is a practice that has been around for a while, but it’s essential to understand the pros and cons of doing so before making a decision. In this article, we’ll delve into the world of flower care and explore the topic of refrigerating flowers in-depth.
Why Refrigerate Flowers?
Refrigerating flowers is a technique used to extend the life of cut flowers. By keeping them cool, you can slow down the aging process and prevent them from wilting too quickly. This is especially important for flowers that are sensitive to heat and humidity, such as roses and carnations.
The Science Behind Refrigerating Flowers
Flowers, like all living organisms, undergo a process called respiration. During respiration, flowers use oxygen to convert glucose into energy, releasing carbon dioxide and water as byproducts. When flowers are cut, their stems are exposed to air, which can lead to a buildup of ethylene gas. Ethylene is a natural plant hormone that promotes ripening and senescence (the aging process). By refrigerating flowers, you can slow down the production of ethylene and reduce the rate of respiration, thereby extending their lifespan.
Benefits of Refrigerating Flowers
- Extended vase life: Refrigerating flowers can increase their vase life by up to 50%.
- Improved appearance: Keeping flowers cool can help maintain their color, shape, and texture.
- Reduced bacterial growth: Refrigeration can inhibit the growth of bacteria and fungi that can cause spoilage.
When to Refrigerate Flowers
Not all flowers benefit from refrigeration. Some flowers, like orchids and succulents, are adapted to dry conditions and may actually suffer from refrigeration. Here are some guidelines to help you determine whether to refrigerate your flowers:
Flowers That Benefit from Refrigeration
| Flower Type | Refrigeration Recommended |
|---|---|
| Roses | Yes |
| Carnations | Yes |
| Chrysanthemums | Yes |
| Tulips | Yes |
Flowers That Don’t Benefit from Refrigeration
| Flower Type | Refrigeration Recommended |
|---|---|
| Orchids | No |
| Succulents | No |
| Gerbera daisies | No |
| Alstroemeria | No |
How to Refrigerate Flowers
Refrigerating flowers is a simple process that requires some basic equipment and attention to detail. Here’s a step-by-step guide to help you get started:
Materials Needed
- A clean glass vase or container
- A floral preservative packet (optional)

- Place the trimmed stems in a clean glass vase or container filled with lukewarm water.
- Add a floral preservative packet to the water, if desired.
- Place the vase in the refrigerator and set the temperature to between 32°F and 40°F (0°C and 4°C).
- Check the flowers daily and change the water as needed.
Conclusion
Refrigerating flowers is a simple and effective way to extend their vase life and maintain their appearance. By understanding the science behind flower care and following the guidelines outlined in this article, you can keep your flowers fresh and beautiful for a longer period. Remember to choose the right flowers for refrigeration, use the right equipment, and follow proper care and maintenance techniques.
Recap
- Refrigerating flowers can extend their vase life by up to 50%.
- Some flowers, like roses and carnations, benefit from refrigeration, while others, like orchids and succulents, do not.
- To refrigerate flowers, trim the stems, place them in a clean vase with lukewarm water, and store them in the refrigerator at a temperature between 32°F and 40°F (0°C and 4°C).
Frequently Asked Questions
Q: Can I refrigerate flowers that are already wilted?
A: No, it’s best to refrigerate flowers as soon as possible after cutting. Wilting flowers may not respond well to refrigeration, and may actually suffer from the cold temperatures.
Q: How long can I keep flowers in the refrigerator?
A: The length of time you can keep flowers in the refrigerator depends on the type of flowers and the storage conditions. Generally, flowers can be stored in the refrigerator for up to 7-10 days.
Q: Can I use a regular refrigerator or do I need a flower-specific refrigerator?
A: You can use a regular refrigerator to store flowers, but make sure it’s set to the correct temperature (between 32°F and 40°F or 0°C and 4°C) and that the flowers are not exposed to direct sunlight or heat.
Q: Can I refrigerate flowers with greenery, like ferns and lemon leaves?
A: Yes, you can refrigerate flowers with greenery, but make sure to trim the stems of the greenery as well and store them in a separate container to prevent moisture buildup.
Q: Can I refrigerate flowers that have been treated with floral preservatives?
A: Yes, you can refrigerate flowers that have been treated with floral preservatives, but make sure to follow the instructions on the packaging and adjust the refrigeration temperature accordingly.
