The “Did You Know?” Series: Did You Know That Flower Food Really Does Work?
Written by Petal Perfection Flower Company
What Exactly Is Flower Food?
Did you know that little packet of flower food that comes with your flowers isn't just something your florist throws into the bag?
It actually serves an important purpose.
If you've ever wondered “Does flower food really work?”, the answer is yes—but it works best when you use it correctly.
Most commercial flower-food formulas contain three important components:
A carbohydrate or sugar provides an energy source that can help certain flowers continue developing and opening.
An acidifier, such as citric acid, lowers the pH of the water, which can improve water movement through the stems while making the environment less favorable for some bacteria.
An antimicrobial ingredient or biocide helps control bacterial growth in the vase solution.
So yes—that little packet is doing more than making the water smell slightly different!
Why Does Flower Food Help Cut Flowers Last Longer?
One of the biggest enemies of cut flower vase life is bacteria.
Bacteria can multiply in vase water and around cut stems. As they accumulate, they can interfere with the flower's ability to take up water.
When flowers cannot take up enough water, they begin to wilt.
Floral preservatives are designed to help address several parts of that problem at the same time.
Research and extension guidance support the use of properly formulated floral preservatives to help maintain flower quality and extend vase life.
More Flower Food Isn't Better
Here's an important tip:
Don't think that doubling the amount of flower food will double the life of your flowers.
It won't.
In fact, using too much floral preservative can potentially harm flowers.
Always follow the mixing instructions on the package.
Correct concentration matters.
Flower Food Isn't a Substitute for Clean Water
This is another common misconception.
Flower food works best as part of good overall flower care.
You still need to start with a clean vase.
You still need fresh water.
You still need to remove foliage that will sit below the water line.
And you still need to keep your flowers away from excessive heat and direct sunlight.
If the water becomes cloudy or dirty, don't simply add more flower food.
Clean the vase, replace the water and prepare a fresh solution.
What About Homemade Flower Food?
There are plenty of recipes online involving sugar, lemon juice, soda and other household ingredients.
Some of these combinations may provide pieces of what a commercial floral preservative does, but commercial floral food is specifically formulated to address hydration, nutrition and microbial control.
University of Florida/IFAS Extension specifically recommends commercial floral preservatives because they are effective at controlling microbial populations and hydrating stems.
So if you received that little packet with your flowers…
Use it!
How to Get the Most From Your Flower Food
For the best results:
Start with a clean vase.
Use clean, fresh water.
Follow the flower-food mixing instructions.
Remove leaves below the water line.
Recut stems when appropriate.
Keep flowers away from heat and direct sunlight.
Change the water when it becomes cloudy or according to the care instructions for your flowers.
These small steps can work together to help your bouquet stay fresh and beautiful longer.

Flower food isn't magic.
But it does work.
