How does each ingredient benefit your flowers?

Besides prolonging your flowers lifespan, what do these ingredients do?

Sugar

In a flowers regular nutrient cycle, glucose is needed for energy. Using sugar in flower food gives it the nutrients it needs to keep growing

Baking Soda

Like bleach, baking soda wards off bacteria and fungi growth

Citric Acid

Citric Acid helps lower the pH of the water which makes it more suitable for your cut flowers

Bleach

Adding bleach to your flower food is optional however, it kills off bacteria, fungi, and microorganisms that block the flower stem and prohibit growth

Steps to Make Your Own Powdered Flower Food

Ingredients

• 2 tablespoons sugar
• 2 tablespoons baking soda
• 2 tablespoons powdered citric acid (can be found in the baking or canning section of grocery stores)
• 1 tablespoon bleach (optional)
• Small airtight container for storage

Steps

1. Measure the ingredients: Gather all the ingredients, and use measuring spoons to ensure accurate proportions.

2. Combine the dry ingredients: In a small bowl, mix the sugar, baking soda, and powdered citric acid until well combined. These ingredients provide essential nutrients and help regulate the pH level of the water to keep the flowers fresh.

3. Add bleach (optional): If you choose to use bleach, add 1 tablespoon to the dry mixture. Bleach helps prevent bacterial growth in the water, which can be especially beneficial if you’re using powdered flower food in larger arrangements or in warm climates. However, it’s important to use bleach sparingly, as too much can be harmful to the flowers.

4. Store the powdered flower food: Transfer the mixture into a small airtight container. Make sure it’s sealed tightly to keep the flower food dry and effective.

How to use the Powdered Flower Food:

1. Prepare your vase: Clean the vase thoroughly with warm, soapy water, and rinse it well to remove any previous residues. This ensures a clean environment for your flowers.

2. Fill the vase: Fill your clean vase with water about halfway full.

3. Add the powdered flower food: Sprinkle 1 teaspoon of the homemade powdered flower food into the vase of fresh flowers. Stir the water gently to help the powder dissolve.

4. Trim the stems: Before arranging the flowers in the vase, trim about an inch off the bottom of each stem at a 45-degree angle. This fresh cut enhances water absorption and nutrient uptake.

5. Arrange the flowers: Place your freshly trimmed flowers into the vase with the prepared flower food solution. The powdered flower food will nourish the blooms and help them last longer.

6. Monitor and refresh: Keep an eye on the water level and the condition of the flowers. Every 2-3 days, change the water, and add a new teaspoon of the powdered flower food to the vase to keep the flowers nourished.

With this homemade powdered flower food, you can enjoy your fresh flower arrangements for an extended period, delighting in their beauty and vibrancy!

Replenish the flower food when you change the water in your vase. A good rule of thumb is every 2 to 3 days.

Does Flower Food Expire?
When making my flower food, I make it mostly on an as needed basis. This powdered recipe can be stored, but my liquid recipe is made to use right away. Because of the nature of the ingredients, unless you are planning to store this mixture for years on end, don’t worry about it expiring on you.

The ingredients in both of these recipes are equally beneficial to the flowers – as stated in the question above, the main difference is the storage. Check out my recipe for Liquid Flower Food Here.
