Helping Flowers Last Longer

Can I use bleach to help fresh cut flowers stay fresh longer?

My favorite way to help a beautiful bouquet of flowers stay fresh longer is to add a very small amount of Clorox® Regular Bleach₂ to the water in the vase before putting in the flowers. All you need to do is add ¼ teaspoon of Clorox® Regular Bleach₂ to 1 quart of cold water and stir. Add this to your vase, and then add the flowers. It also helps if you cut a little off the bottom of each stem immediately before putting them in the vase.
