How do the florists keep the flowers fresh and blossoming?

It is a sunny day, where the sun is smiling with a rising temperature, making it difficult for the florist to store and transport the blooms, as the heatwave makes them die in a jiffy. When the flowers come in contact with the direct sunrays or heatwaves they start battling for their own lives and try to stop themselves from wilting. 

How long do the flowers last?

When you are storing cut flowers you must know what ambiance they strive to survive, for storing them in the best way, you need to know the temperature at which they perform best.  Plus, it is also important that you must differentiate between the species which are intended to be kept preserved. The majority of the flowers require a temperature between 33 F- 37 F while the blooms which are a little sensitive or we can say cold sensitive or tropical flowers are advised to keep maintained at a temperature ranging above 50 F.

Atmospheric Temperature:

Generally, the normal atmospheric temperature needed for cut flowers should be closely regulated. Things that should be monitored carefully are the thermal condition of the storage facility as it should not get exceeded 40 F.

Water Temperature:

When fresh flowers got cut, they were dipped in the water and saved from dehydration. Most florists use lukewarm water. If we remove a few exceptions then hydration with warm water is best as the warm water’s molecules are easily absorbed in the stem of the flowers in comparison to the cold water. In the majority of cases, the best temperature for flowers are range between 100 F – 110 F.

How long can a bloom survive in the cooler?

Flowers are perishable items that can be easily spoilt. Flowers live in florist’s places as a guest only, they use their place as a rest stop, and as soon as they are required by someone they leave their place. And their real-life starts in their customer’s abode, so they need to survive there for a long time, almost a week.

It is necessary to know that one must not keep the flowers for more than five days in the cooler, they used to sell them as soon as they can. Processing and rotating the blooms in the cooler is a good practice, which aids blooms in keeping themselves brighter & healthy. Rotating of flowers regularly in the way of first-in and first-out. Always walk on the care and handling guidelines. Florists must be conscientious about the hygiene of the cooler. If the cooler is full and dirty, don’t keep flowers there for more than one day. 

Why flower cooler?

In this hot temperature where humans are melting, getting exhausted, and draining all their energy, flowers being fragile beings are also always on the verge of being dried. The flowers which are freshly cut will get rotten if they are kept at room temperature and ordinary coolers are not able to fulfill the requirement of the flowers to be fresh. As the common coolers run with very dim humidity and flowers got dried and damaged owing to their low humidity. 

Flower coolers have the quality of keeping the temperatures at 36-41 Fahrenheit, which helps in elevating the shell life of the cut flowers and plants. Flower coolers can be customized too, as per the requirement.

Why do we keep flowers in the cooler?

After reading the above, you must be quite clear that keeping the flowers in the coolers helps in extending their life. But why? 

The answer can be found in two processes by which each plant goes through and that is photosynthesis & respiration.

Plants are more sufficient than animals as they can prepare their food, if your mindsight is good you will vividly remember your chapter on biology in which you have read about the photosynthesis process, in this process pants take carbon dioxide, water, and sunrays and then transform it into sugar (for the food)

You must be curious to know how respiration and temperature cause affect the cut flower?

The amount of food or the respiration taken by the plant is solely dependent on the temperature. The lower the temperature, the slower the rate of respiration.

For instance, when a rose is harvested, it will not be able to prepare any food of its own, which will automatically lead to its death. The rose must rely on the food which it has reserved on its leaves. Storing the cut rose flower slows down the rate of respiration and helps in conserving the food which ultimately results in the long life of the rose bloom.

What temperature will be best for the cut flowers?

For cut flowers, the temperature that will make them grin is above 33F, but one must be cautious as to when the temperature drops down to 32F or lower, flowers may face freezing hindrance and can die slowly. Thus, the best temperature for the cut flowers is between 34F and 37F, it’s just a matter of a few degrees as it can take the life of flowers or give a long life to them. Are you aware of the fact that keeping the flowers at a low temperature lowers the risk of flowers getting damaged by the ethylene and reduces the growth of microbes that clogs the stems and reduces longevity?

Tropical flowers

Now you have got the idea that the cut flowers are perfectly stored between 34 to 37F, but tropical is a little different, they have grown up in such hot climates, thus the cooling temperature for example below 50F can kill them immediately. Keeping them at this low temperature can cause chilling injury which affects the physiological process of the plant, thus it is advised to keep the tropical flower temperature above 50F.

Plants keep themselves all fed by making food through the process of photosynthesis, then transform the sugar(food), into energy so that their cells can be alive via the process of respiration. Flowers are kept in cold storage to elevate their long life by slowing their use of food reserves, they have been in themselves while growing naturally.
