Bringing fresh cut flowers home or receiving them as a gift never fails to brighten up your day, but there's no way to know how long they'll last. Sometimes, you only get a few days with your perky bouquet before it starts to wilt, while other bunches may last up to a week.

There are a ton of tips and tricks out there on the internet, but what really works? The Spruce team tested five different methods to find out how to keep flowers fresh the longest—watch the video below to check out our findings.
The Test
We placed five bunches of roses in five separate vases and added the same amount of water to each. Next, we added a method to four of the five vases, leaving one bunch of roses in plain tap water to serve as the control. We placed the vases in a location with lots of light, and filmed a timelapse over the course of one week to measure how each method held up against time, and against each other.
The Methods
We trawled the internet looking for popular methods of keeping bouquets fresh and found a number of options. We whittled down our list to the four methods that are searched for the most often.
Water: Our Control
Reaching back to memories of our sixth grade science class, we knew our test should have a control to compare each of our variables (our different methods) to. Besides, cut flowers have been thriving for ages in plain water and sometimes the simplest ways are the best.
Flower Food Packet
The packet you receive in your bouquet is not just there for show. It is specifically designed to preserve the vitality of your flowers. Flower food is made up of just three ingredients: citric acid, sugar, and bleach. The citric acid lowers the pH of the water, which makes it more habitable for flowers. Flowers produce sugar, their food source, during photosynthesis, so when they're cut, and their leaves removed, they produce far less sugar. Adding sugar to the mix helps the flowers feel like they're eating food (hence the name "flower food"). Finally, the bleach helps disinfect the water and rid it of any harmful bacteria that may compromise the health of the bouquet.
Aspirin
Aspirin lowers the pH of the water, which can help flowers live longer. Gardeners and Flower enthusiasts often offer the recommendation to crush a 250- to 500-mg aspirin tablet per gallon of water so it absorbs more quickly. You do this by using a mortar and pestle, or placing the aspirin into a sealed baggie and crushing it with a flat-bottomed, heavy object (bottle of wine, coffee table book, etc).
Vodka
While we assumed adding alcohol to our flowers would kill them instantly, we were surprised to find that vodka inhibits the flowers' production of ethylene, which helps them mature and, eventually, wilt and die. A few online resources also noted that vodka can function as the bleach in flower food does by eliminating the bacteria in the water, which could inhibit the flowers' longevity.
Sexual Performance Enhancer
Possibly the most shocking method on the list, our last variable was a common sexual performance enhancer. We're not exactly sure how or why this method became popular (prescriptions are expensive people!) but we discovered that your average SPE contains nitric oxide, which can slow down the aging process of plants and flowers and thus, help them to live longer. Crush the little blue pill (or white pill, if you're going the generic route) with a mortar and pestle, for the ultimate effect.
The Results
After running the timelapse for one week, the results were clear. The flowers with the flower food packet were still standing straight up, and their petals felt silky and hydrated, as if they were bought just a day or so ago. All the rest of the flower bunches were significantly slumped over compared to the vase with the flower packet, though the vase with aspirin was doing slightly better than the others. That said, the stems on the flowers that soaked in that aspirin had turned dark and dry, almost as if they were rotting away.
The vases with water and vodka tied for fourth place, though the flowers that were exposed to the vodka were significantly silkier than any of the four runners-up. Finally, perhaps too ironically, the sexual performance enhancer was the big loser of the week—despite the presence of the SPE the flowers drooped over and dried out faster than any other bunch.

The Bottom Line
Next time you buy or are gifted a bouquet, don't throw that flower food packet away! Add it to your water to keep your flowers looking fresh all week long. If you didn't happen to get a flower food packet with your blooms, don't worry—you can make your own flower food at home using just a few simple ingredients.
As an enthusiast with a deep understanding of floral care, I can confidently address the concepts presented in the article on keeping flowers fresh. The Spruce team conducted a comprehensive test using five different methods to determine the most effective way to prolong the freshness of floral arrangements. Here's a breakdown of the key concepts discussed in the article:
-
The Test:
- The experiment involved placing five bunches of roses in separate vases, adding the same amount of water to each.
- Four of the vases received additional methods, while one served as the control with plain tap water.
- The vases were exposed to light, and a timelapse over one week was filmed to assess the longevity of each method.
-
The Methods:
- Water (Control): The simplest method, harking back to basic floral care principles, served as a control to compare other variables.
- Flower Food Packet: The packet accompanying bouquets contains citric acid, sugar, and bleach. Citric acid lowers water pH, sugar provides nutrition, and bleach disinfects the water.
- Aspirin: Aspirin, when crushed and added to water, lowers pH and is believed to extend the life of flowers.
- Vodka: Surprisingly, vodka inhibits the production of ethylene, slowing the maturation process of flowers. It may also act as a disinfectant.
- Sexual Performance Enhancer (SPE): The article explores the unconventional method of using a common sexual performance enhancer containing nitric oxide to slow down the aging process of flowers.
-
The Results:
- After a week, flowers with the flower food packet demonstrated the best results, remaining upright with silky and hydrated petals.
- Aspirin-treated flowers were better than others, but the stems had darkened, possibly indicating damage.
- Water and vodka-treated flowers tied for fourth place, with vodka-exposed flowers having silkier petals.
- Surprisingly, the sexual performance enhancer performed poorly, causing flowers to droop and dry out faster than others.
-
The Bottom Line:
- The article concludes that using the flower food packet, if included, is the most effective way to keep flowers fresh.
- In the absence of a flower food packet, the article suggests making a homemade flower food using simple ingredients.
In summary, the article provides practical insights into various methods of maintaining floral freshness, debunking myths and highlighting the importance of the often-overlooked flower food packet.
