Fill your sink halfway to the top with lukewarm water, and place the stems of the roses into the sink.
Cut the stems by 2 or more inches in the water at an angle to expose the plant tissue. Fill a vase with lukewarm water and place the roses into the vase.
Leave the roses in a warm room at a temperature of at least 74 degrees F. The bud's blooming time varies depending on the variety of the rose; for example, hybrid teas and grandifloras tend to bloom faster and fuller than roses of the polyanthas variety.
