Precautions for fresh-keeping of flowers:
1, appropriately trimmed.
These bought flowers look beautiful, but they fade easily, such as the roses below. We need to cut off the stems at the bottom of these bouquets 1~3 cm, and do not trim the growth nodes, so as to ensure the bouquets to absorb water better. We cut them short every few days to keep them fresh and attractive.
2. Disinfection of flower stems.
If your bouquet is herbaceous flowers, you can soak it in warm water 15~25 seconds, and the water temperature is about 50~60 degrees. You can also burn the bottom of the flower stem with a lighter, which can sterilize and promote the water absorption of the flower stem. Don't try woody flowers.
3. Keep the water active.
If you want to keep the bouquet fresh for a long time, you need to constantly change the water, preferably rainwater or pure water, every 2~3 days, and then use tap water after 3 days. Moreover, the leaves and flowers of the bouquet should not be soaked in water, otherwise they will rot easily and produce germs.
4. Pay attention to the placement position.
Keep the bouquet away from oil smoke or second-hand smoke. Don't put it in the sun, next to heating and air conditioning, which will make the flowers wither. Don't put it next to fruits, such as apples and watermelons, which will easily make the flowers wither.
5. Deal with it regularly.
Flowers bought by flower shops should be checked and cleaned frequently. If branches and leaves wither and flowers wither, they should be cleaned up in time. If you are sick, you will cut off the withered flowers in time to prevent them from producing rotten substances, which will not only affect the viewing, but also produce bad smell.
