How to Keep Flowers Fresh

Did you know? Adding Clorox® Disinfecting Bleach to flower vase water keeps flowers healthy and last longer!

When microorganisms multiply in plain vase water, they block the flower stem and make it hard for the stem to absorb water for nutrients — causing wilt and odors! Adding Clorox® Disinfecting Bleach kills these microorganisms to ensure that your flower bloom lasts.

With a couple cents worth of Clorox® Disinfecting Bleach, flowers can last longer and water doesn’t get funky as fast. Here’s how:

  1. 1


    Using gloves, add ¼ teaspoon of Clorox® Disinfecting Bleach to every 1/3 gallon of water you use in the flower vase and stir to mix.

  2. 2


    Unwrap the bouquet and cut a little off the bottom of each flower stem to increase absorbency. When cutting the stems, make sure to also consider cutting them to size for your flower vase.

  3. 3

    Refresh Weekly As Needed

    Ensure the water stays clear and free of that nasty smell that starts to brew about a week after the flowers bloom. Check the flowers weekly, and mix up a fresh batch of water solution as needed.
