1, boiling water
We can take a physical measure to keep roses fresh for a long time. The reason why the rose will wither quickly is because the tissue fluid of the rose itself is lost too quickly at the incision of the branch. We can boil the cut in boiling water for 10 second, and then quickly put it in cold water, so that the tissue fluid of the treated rose itself will not lose too quickly, thus prolonging the flowering period of the rose.
2, vitamin C.
Vitamin c can play a very good role in protecting flowers. You can put vitamin C directly in the vase of flower arrangement, or you can mash a piece of vitamin C into water and add a little sugar, then cut off the bottom of the flower diameter and put it into a water bottle filled with vitamin C or sugar, which can better keep the freshness of roses.
3. tea
Usually, we usually put flowers directly in clean water, and the longest flowering period is only two or three days. It is said that using tea instead of water will prolong the flowering period, and the higher the concentration of tea, the better. This is just an online statement. Bian Xiao has never tried it, but you can eat crabs.
Step 4 keep fresh with beer
In order to prolong the flowering period, some friends buy special preservatives, which is actually unnecessary. Beer at home is the best preservative. Adding a little beer to the vase containing roses can prolong the shelf life of roses. As for the principle, because beer contains ethanol, it can sterilize and keep fresh the flower branches of roses, and because beer contains nutrients such as sugar, it can provide nutrition for the branches and leaves of roses, so roses can be preserved for a long time.
Step 5 use detergent
There is no preservative at home, so we can make it ourselves. The main material is detergent. Just mix a small amount of detergent into warm water with a concentration of 2%-4% and a preservative. Soak the cut roses in 5 cm deep detergent solution, and the fresh-keeping period of flowers will be increased by 2-3 times!
