1. You can cut off a branch at the bottom of a rose on a slope and put it in a bottle. Because the slope will increase the cross section of the flower branch in contact with water, so that the flower branch can be kept for a longer time.

2. Adding half a spoonful of salt to vase water can resist hydrolysis and oxidation. Be careful not to put too much salt.

3. Burn the bottom of the rose and block the incision to prevent nutrients from leaking from the inside of the flower branch.

4. Putting a bottle of formalin or vitamin in the vase will make the flower branches get nutritional supplement.

Don't put too much beer in the vase. Beer contains alcohol and a small amount of sugar, similar to alcohol, which can disinfect the flower branches to prevent cross-sectional infection.

6. Inserting the flower branches into the cooled tea can provide nutrition for the flower branches and prolong the flowering period.

7. Avoid direct sunlight, which will make the nutrients in the flowers evaporate quickly.

8. Water the flowers often. Change the water for the flower branches every one or two days and spray an appropriate amount of water on the petals.
