1, put the roses in a cool place to prevent direct sunlight. By the way, peel off a few petals on the outer layer of the flower, which is beneficial to preservation.

2. You can also use scissors to cut the roots of roses obliquely, so that roses can absorb as much water as possible. Be careful not to let the leaves of roses touch the water, or the leaves will rot easily if they are soaked for a long time.

3. For long-term preservation, a little potassium permanganate or salt can be added to the vase, which can make the color of the rose bud more vivid and lasting. But we should also pay attention to changing the water frequently and keep the water in the bottle clean.
