Ingredients For Preventing Mold From Fresh Cut Flowers:
- 8 oz water
- 1/2 tbsp 3% hydrogen peroxide
- Glass vase or jar
Directions:
- Prepare your fresh cut flowers by trimming the ends off and rinsing them in water.
- Fill a vase with 8 oz of water, then 1/2 tbsp of peroxide (if you need more water, keep these ratios. For instance, you can use 16 oz of water and 1 tbsp of peroxide).
- Add your fresh cut flowers to the peroxide water.
- You can repeat these steps every few days.
How Long Will This Last?
I had these flowers in a vase for about 3 weeks and there was no mold growth! Eventually the blooms started to wilt, but I didn’t get any yucky water this entire time. I clean out the vase every 3 days and redo this solution when I have fresh flowers.
Things to Keep In Mind for Adding Hydrogen Peroxide To Fresh Cut Flowers
You can try this simple hack, and you will be impressed with how well it works! But there are always important things to keep in mind when you work with hydrogen peroxide.
Hydrogen Peroxide Is Reactive To Light
The reason peroxide is stored in dark bottles is how reactive it is to light. It will decompose when it is exposed to light overtime. You will probably be using a glass vase to add your fresh cut flowers, so it can deactivate the peroxide over a few days to a week. I personally change out this solution every 3 days or so. This works great for my blooms! Once I tested out keeping this water and peroxide solution alone for a week, and it still worked. Just keep this information in mind!
Hydrogen Peroxide Prevents Bacterial and Fungal Growth
When you use this simple hack for keeping away mold, it works to prevent bacteria and fungal growth in the water. Peroxide is an anti-microbial, so it works well for plants. Also, this interesting study shows how hydrogen gas inhibits bacterial colonization. This is about hydrogen gas, but the science is similar for using hydrogen peroxide.
This Can Also Boost Blooms
It is a known fact that hydrogen peroxide boosts blooms. The extra oxygen molecule enhances growth and color for flowering plants, and this includes fresh cut flowers too! You can watch the coloring of your fresh cut flowers deepen when you use hydrogen peroxide like this.
Hydrogen Peroxide Has So Many Household Uses
