The freshness of fresh flowers
Fresh-keeping time of common flowers
The freshness of fresh flowers varies by type. Generally speaking, fresh-cut flowers last about a week. For example, roses usually stay fresh for 3-4 days, while lilies can stay fresh for 10-15 days.18 The fresh-keeping time of carnations is longer, up to about 15 days, while the small chrysanthemum can be kept fresh for about 10 days.
The influence of season on preservation time
Seasonal changes have a significant effect on the freshness time of fresh flowers. In the summer high temperature environment, the fresh flower preservation time will be shortened to 2-3 days, and in the winter, due to the low temperature, flowers can be kept fresh for 10-15 days.
Factors affecting fresh flower preservation
Types of flowers
Different kinds of flowers because of their different physiological characteristics, fresh-keeping time is very different. For example, stars and gardenias last longer, while tulips last shorter.
Environmental conditions
Temperature, humidity and light are important factors affecting fresh flowers. High temperature and high humidity will accelerate the decay of flowers, while low temperature (about 18 ° C) and moderate humidity can extend the preservation time.
Maintenance method
The proper maintenance method can significantly extend the fresh-keeping time of flowers. For example, regular water changes, pruning of flower branches, and the use of preservatives are effective preservative measures.
Scientific preservation method
Trim and change the water
Before the flowers are inserted into the water, the bottom of the flower branches should be cut 2-3 cm diagonally to increase the water absorption area. Changing the water once a day and cleaning the container can prevent the growth of bacteria and extend the preservation time.
Use preservative
Adding a small amount of sugar, salt or vitamin C to the water can provide nutrients for flowers and inhibit bacterial growth. In addition, commercially available flower preservatives can also effectively extend the fresh-keeping time.
Control your environment
Keeping flowers in the shade, out of direct sunlight, can slow the pace of flower decay. Ice can be added to the vase in summer to reduce the water temperature.
Tips for extending fresh flowers
Choose the right container
Using a clean vase and ensuring a moderate amount of water (about 1/3 to 2/3 of the container) can provide a good growing environment for flowers.
Remove excess leaves
Removing all the leaves submerged in water prevents bacterial growth while reducing water evaporation.
Trim regularly
Trimming the bottom of the flower branches every 2-3 days can maintain the water absorption capacity of the flower branches and extend the freshness time.
Conclusion
Although the fresh-keeping time of flowers is limited, through scientific maintenance methods, we can maximize their beauty. Whether it is daily home decoration or holiday gifts, understanding the fresh flower preservation skills can make us better enjoy the beauty of flowers. Hopefully this article has provided you with practical guidance to keep flowers blooming in your life longer!
