How Does Bleach Help Flowers?

Why Use Bleach in Flowers?

Bleach is a powerful cleaning solution because it disinfects surfaces and kills germs. In the same way, it is also an effective substance to place in the water of cut flowers. Bleach prevents bacteria from growing inside the vase. This bacteria will wilt flowers prematurely and cause the water inside the vase to become moldy. Bleach works similar to the small packets that often come along with flowers at the florist.

Preparing a Bleach Solution

Bleach should be added to the water inside a vase every few days to keep the flowers fresh and free from bacteria. Do not estimate how much bleach you are adding to your water, or you may accidentally add too much and cause the flowers to wilt prematurely. Place 1/4 tsp. of bleach into a quart of water and mix thoroughly. Pour enough solution to completely cover the cut stems of the flowers and discard the rest. Every four days, apply another 1/4 tsp. of bleach to a quart of water and stir, or pour out the water and make a new solution, then pour it back into the vase. Using bleach to preserve flowers is more effective than preserving packets available at the florist.

Warnings About Bleach

Bleach must be treated with care, especially if it is being used in the home. Although breathing in bacteria that grows in a flower vase is dangerous, breathing an undiluted quantity of bleach in an unventilated area can also be dangerous. Use only a small amount of bleach to preserve flowers, and if the smell of bleach is still present in the home, open a window near the vase until the smell dissipates. Take extreme care when pouring bleach, and avoid getting it in the eyes or on the skin. If bleach gets into the eyes or mouth, flush the area with water and call Poison Control immediately.
