Guide to Extending the Vase Life of Roses in Hot and Humid Cities like Hong Kong

11 Jan

Roses are known for their beauty and fragrance, but in hot and humid cities like Hong Kong, they can quickly wilt if not properly cared for. Follow these tips to extend the vase life of your roses and keep them looking fresh and beautiful for longer.

1. Selecting Fresh Roses

Choose roses with tight buds that are just starting to open. Avoid roses with fully open blooms, as they will have a shorter vase life.

2. Properly Preparing the Roses

Upon bringing the roses home, trim the stems at an angle under running water to prevent air bubbles from forming in the stem, which can block water uptake.
Remove any foliage that would be submerged in water, as this can promote bacterial growth.

3. Choosing the Right Vase and Water

Select a clean vase that is the right size for the number of roses you have. A vase that is too small can crush the stems, while one that is too large can cause the roses to droop.
Fill the vase with lukewarm water to about two-thirds full, as roses absorb warm water more easily.

4. Adding Preservatives

Use a commercial floral preservative or create your own by adding a few drops of bleach and a teaspoon of sugar to the water. The bleach helps to kill bacteria, while the sugar provides nourishment for the roses.

5. Placement and Environment

Keep the roses away from direct sunlight, drafts, and appliances that generate heat, as these can cause the roses to wilt more quickly.
In a hot and humid city like Hong Kong, consider placing the roses in a cool, air-conditioned room to prolong their vase life.

6. Regular Maintenance

Change the water every two days and re-trim the stems to ensure the roses can continue to drink properly.
Mist the petals with water to keep them hydrated, especially during dry and hot weather.

7. Troubleshooting

If the roses start to wilt, try recutting the stems under water and placing them in hot water for an hour to revive them.

By following these tips, you can extend the vase life of your roses even in the hot and humid conditions of a city like Hong Kong, allowing you to enjoy their beauty for a longer period.
