Let's talk about novelty first It takes a fixed time for all fresh cut flowers to be cut from the mother until they finally bloom and wither completely, so the sooner they enter your vase, the longer their life will be. Therefore, freshness is the premise of prolonging flowering period. If the freshness of the flowers you buy is not good, then the following things will not be mentioned.
When it comes to flower preservation, there are only three things: sterilization, nutrition and ethylene control.
Sterilization: Why sterilization? Flowers bloom by absorbing water from roots to flower heads and constantly providing water and nutrients. If the confession is broken, there is only one dead end. This is the harm of bacteria. The flower head absorbs water through the catheter in the stem. A large number of bacteria will block the catheter, block the supply of water, and eventually cause the flowers to wither before opening. How to disinfect? There are many legends: adding vinegar, salt, citric acid and so on. ............................................................................................................................................................
Nutrition: This is easy to understand. With sufficient nutrition, the flowers will bloom fuller, brighter in color and last longer. The legendary sugar and cola are basically for this purpose. But once these things are added, there will be nutrition, but at the same time, bacteria will multiply. In fact, in the end, if you can't get these nutrients, you will eventually die of depression. So, please don't add such things easily.
Ethylene control: ethylene is a gas, which will accelerate the senescence of flowers and inhibit the opening of many flowers, and the flowers themselves will also produce this gas. How to control this gas effectively is a technical job. I'm from a flower shop. I've been failing chemistry at school, so I don't know much about it. I just read that some unstable silver salts are at work, and I'm afraid we can't handle them ourselves. The only thing we can do is to keep the flowers away from the ripe fruits. The fruits will volatilize ethylene, which will induce the flowers to produce more ethylene gas.
The treatment of each flower, this is also quite critical, several points: flowers, leaves, stems.
Flowers, remove the rotten petals on the outer layer (if any). Here, we focus on roses. Really fresh roses usually have several outer petals on the outer layer, which are not so beautiful and regular, sometimes with a little green, and the texture is thicker and harder than the inner petals. We call it protecting petals, which is a good thing. It has played a great role in making the flowers bloom less quickly. First of all, she can protect the internal petals from damage, and at the same time, because it is hard, it also plays a role in supporting the internal petals, which can make the internal petals open slowly instead of all at once. In fact, when the flower is fully open, the protective petals will turn down and disappear. In my opinion, roses with protective petals look brighter and more layered.
Leaves, broken leaves should be removed, water can't be sucked in anyway; Rotten leaves should be removed; The leaves below the bottle mouth should be removed; The unsightly leaves should be removed; Don't remove all the leaves. One function of leaves is to help flower heads absorb water. If all the leaves are removed, the flower will not live long.
It is best to simply clean the leaves of the flowers before they enter the water, otherwise it will accelerate the turbidity of the bottle. Here I will focus on root cutting, which is as important as sterilization and belongs to the most important category. Explain the terminology first. What is root cutting? Root cutting refers to cutting off the root of the flower stem at 45 degrees or cutting off a section of 2-3 cm with sharp scissors or Swiss army knife to expose new stubble. Why do you want to show new stubble? If you buy flowers from a flower shop for a few days by mistake and the roots are soaked, you must remove all the soaked parts until you see that the incision is white and fresh, otherwise it will be cut in vain and will not absorb water. Why do you want to cut at 45 degrees? Because this can increase the contact area between the flower stem and water, which is beneficial to water absorption. Then let's talk about how to cut it. According to our industry standard, cutting in water means cutting in water. Why? As mentioned earlier, the water in the flower head is sucked up by the catheter in the flower stem. In addition to bacteria, there is another thing that will block the catheter, that is, air and small bubbles. After the stem is cut and left in the air for a long time, the air may enter the conduit, causing air resistance, so that the water cannot be sucked up. The final result is that the flower withers before it opens, so the industry standard is to cut it in water, so the air cannot enter. Actually, I've never cut flowers with water, but I'm sure I'll put them in a vase with preservatives immediately after cutting them, without any delay, so the flowers in our shop generally don't dehydrate. Remember one thing: as long as the root of the flower stem is out of water, the root must be cut off when you put it in.
Finally, talk about the environment. What environment can last?
The first is the temperature. The ideal storage temperature of most fresh cut flowers (except some tropical flowers) is 5 degrees Celsius. Of course, people can't stand this temperature and have to wear down jackets. Then at a temperature of about 20 degrees, flowers will be more comfortable and live longer.
Then there is humidity. If the air humidity is higher, the flowers will be moist when they are alive. If it is too dry, some flowers can't stand it, such as hydrangea. This elf with petals hangs easily. So it is difficult to keep hydrangeas at home in winter in Beijing. If there is a humidifier at home, it is estimated that Hua will thank you from the heart! Really can't. The petals of roses and lilies don't touch water very much, and there are few petals. You can spray some water on flowers and leaves in the form of water mist, which can also play a role in humidification.
Ventilation, this is really important. Open the window regularly for ventilation, so that ethylene gas can quickly stay away from flowers. The flowers must be cold. I swear to stay with you for a few more days.
Don't be exposed to direct sunlight, which is the opposite of potted plants with roots. Otherwise, when the water evaporation rate of flowers is faster than the water absorption rate of roots, in the same way, stay away from cold and heat sources, such as heating and air conditioning outlets. Like I said before, ripe fruit.
A tip for arranging flowers: Don't look at those pictures on the Internet. Flowers one after another, squeeze one after another. That's cheating you into spending more money. Ignore them. Gao Yanfa, a master of floral art in Singapore, said that there should be room for butterflies to pass through when arranging flowers. Why do you say that? When arranging flowers, leave open space for them, and at the same time, the air can circulate freely, bringing fresh air, so just look at your vase and buy flowers at the right time, and don't spend impulsively.
Step 1: Put the flowers aside, clean the vase first, thoroughly clean the vase with .84 disinfectant, and then rinse it with clear water.
Step 2: Mix preservatives. Mix preservatives (preferably pure water or mineral water) in proportion and pour them into a clean vase.
Step 3: It's the flower's turn. Contrast the vase, remove the leaves under the bottle mouth, remove the bad petals, and simply clean the stems and leaves.
Step 4: The important step is root cutting. Every flower is put into a vase immediately, immediately, immediately, immediately and quickly after the root is cut. Don't delay.
Step five, find a reliable place to put it after all the plugs are inserted. Don't watch it often, just make up a little when it is short of water.
