Sugar is a carbohydrate. After a flower is cut, it stops receiving nutrients from the soil, which is one of the reasons for its withering.
Many resources write that you need to add citric acid or sugar to a vase with a bouquet in order to prolong the life of the plant.
Yes, indeed, these substances nourish flowers. However, for example, citric acid increases the acidity of water, so bacteria begin to multiply in it more actively.
Of course, the flower needs carbohydrates. Nevertheless, sugar is also a bait for all kinds of bacteria.
Once you have placed your cut roses in a vase, you should change the water every one to three days.
The best thing to do is to look at the water and change it when it appears cloudy.
Having fresh water prevents the buildup of bacteria that can attack your roses and also helps avoid unpleasant odors.
1-2 tablespoons of sugar added to water will prolong the life of living flowers.
You need to trim flowers and change water daily. This is perhaps the main secret of the long life of almost all flowers.
Every day you should trim the stems by 1 cm and fill the vase with clean water.
