1, chemical preservative

Some ingredients in chemicals can keep fresh. Mixing a proper amount of chemical preservatives with water and stirring them evenly, adding them into the aqueous solution of flower arrangement can slow down the withering of petals and branches and prolong the fresh-keeping time of flowers. The most commonly used chemical preservatives are alcohol, boric acid, alum, citric acid, potassium permanganate, camphor, salt and so on. At the same time, aspirin aqueous solution can also be used as a chemical preservative.

2. Nutritional preservatives

Flowers need nutrition besides water, otherwise they will wither quickly because of lack of nutrition. Sugar, vitamin C, beer and other nutrients can provide nutrients for flowers. The soda we often drink can also be used as flower nutrient solution after dilution.

Because the roots of flowers need to be soaked in water for a long time, they are easily attacked by bacteria. Therefore, appropriate amount of salt or vitamin C can be added to the water to prevent bacterial invasion.

3. Water cutting method

This method is mainly to enlarge the section at the bottom of the flower stem and increase the water absorption area. Trim the bottom of the flower stem neatly and trim it into an inclined plane; The water in the vase should not reach two-thirds of the flower stem as much as possible. This method is suitable for most flowers, especially peony, carnation, narcissus and so on. After standing for a period of time, impurities or sediment will be attached to the bottom of the flower stem, so pruning 1-2cm every one or two days can also extend the flowering period.

4. Crushing method

The principle is the same as the water cutting method, that is, the bottom of the flower stem is broken to increase the water absorption area of the stem. This method is suitable for lily, hydrangea, chrysanthemum and so on.

5, beer method

Beer can be used as a nutritional preservative to prolong the survival time of flowers, because the ethanol in it has the function of disinfection and antisepsis, and the nutrients such as sugar in it can provide more nutrition for flowers. Therefore, adding a proper amount of beer to water or putting flowers in a beer bottle with foam can prolong the flowering period.
