How to Care for Cut Long-Stem Roses That Are Drooping

Fill a vase or container with lukewarm water -- approximately 110 degrees Fahrenheit. Add a commercial flower preservative to the water, using the amount indicated on the label for the vase or container size.

Remove the leaves on the bottom half of the long-stem roses so that none will be submerged under water. Pinch them off or use a pair of hand clippers.

Fill a shallow container with lukewarm water. The container should be strong enough that it can withstand being cut on. A glass cooking pan, for example, may work.

Place the end of the long-stem rose in the water, and cut the end off at a 45 degree angle, about 1 inch from the bottom. Do this under the water, making a sharp cut. Transfer the rose to the vase. Repeat for all the roses.

Set the rose arrangement in a cool location, such as in a refrigerator or cool garage, for the first two hours. The roses will absorb the warm water without losing too much moisture through the petals and leaves, according to University of Minnesota. The drooping or wilted roses should revive themselves and be ready for display after the two hours.
