If you receive a bouquet of roses for your birthday or other holiday, you can preserve them with Clorox bleach. The bleach works by killing bacteria that break down the flowers. The important thing is to stick to the designated amount of Clorox as too much will kill the flowers and too little won't kill the bacteria.
Pour room temperature water into a flower vase. Using water that is too hot or too cold will shock the flowers.
Add the sugar and Clorox to the water in the vase. Stir until the sugar and Clorox have dissolved.
Cut the stems of your flowers back about 1 inch with a pair of garden scissors. This will get them ready for the water.
Set the flowers in the vase immediately after cutting the stems.
Change the water in the vase every couple of days. Make sure you add more Clorox and sugar to the water to keep the flowers fresh.
