Why do cut roses droop their heads?

A cut-rose bouquet adds both fragrance and beauty to a room. A few steps in the cutting process will help prevent roses from drooping in the vase. Roses droop from dehydration, bacteria or a lack of sugar.
When a rose is cut from the bush, an air bubble often becomes lodged in the stem of the plant once it is placed in water. The air bubble blocks the flower's ability to suck up water. Consider recutting the rose flower's stem under warm water prior to putting the flower stem in the vase to prevent an air bubble from forming. This will prevent the flower from drooping.
Adding a floral preservative that provides sugar and nutrients to the water will prevent drooping. Floral preservatives are available at most garden supply stores and florists. Adding a bit of sugar to the water prior to placing the cut flower stem into it can also help prevent early drooping.
Cut rose flowers in the early morning or late afternoon when the plant has the maximum amount of sugar within its stems. Watering the day before cutting a bouquet will also help hydrate the blossom and prevent early drooping once cut.
