Rose maintenance:
1, to prevent the flower head from bending, you can cut the stem base obliquely, wrap the flowers and leaves with newspaper, and immerse the whole handle in water to absorb water.
2. If the head has broken, cut off the base in warm water and insert it into the fresh-keeping liquid with pH of 3.5 ~ 4.5 to recover.
3. When finishing, the loose petals on the outer layer can be removed, and the thorns and leaves inserted into the water can be removed. In order to prevent the wound from being infected by bacteria, bleach or preservative should be used to make the bottle last longer.
