How to Keep Cut Flowers Fresh (Almost) Forever

Everything you need is already hiding in your kitchen.

There’s no denying the instant boost that fresh flowers can give to any room. Be it a generous arrangement you’re lucky enough to receive, or a bunch you grabbed from Trader Joe’s, flowers—or even just leafy stems, for that matter—can make any room feel warm and inviting.

But there’s also something deeply upsetting about tossing a wilted bouquet; it always feels like it was just yesterday that you were fluffing up your still-closed ranunculus, and suddenly they’re stinking up the kitchen with their funky water. So, how does one go about keeping pretty blooms alive for more than a few days?

Below, Christina Stembel, founder of Farmgirl Flowers shares her best tips for extending the life of your stems, along with her homemade flower food recipe—much like the little packets that come with a bouquet.

1. Use a Dark Vase

First things first: “We strongly recommend using either a dark glass vase or ceramic vessel,” says Stembel. “Darker glass or ceramics won’t allow sunlight into the water, which can increase the rate at which the stems decay.” Sure, mason jars are adorable, but if you’re planning on displaying the bouquet where the indirect sun hits, go for a darker vessel.

2. Add DIY Flower Food

“When we first started making flower food, we followed an older recipe from Martha Stewart (the queen!),” Stembel says. "Since then, we’ve made a few tweaks to suit our production and the ingredients we have on hand.” Farmgirl's industrial formula is: 1 gallon of water + 4 teaspoons bleach + 4 teaspoons vinegar + 4 tablespoons sugar. To scale that down for your own bouquet, go with 1 quart water, 1 teaspoon bleach, 1 teaspoon vinegar, and 1 tablespoon sugar.

Bear in mind, according to Stembel, “The truth is, flower food is most effective for flowers that are fresh cut.” But as the flowers age, they still get a boost from this DIY food and the bleach component also helps to kill bacteria. Some people even use Sprite or other clear sodas as sugary flower food. If you take this route, Stembel still recommends a little bleach (in the same proportions as earlier stated), but with one-part clear soda to three-parts water. Don't use diet soda because there's no sugar and make sure it’s a clear variety, like Sprite. Colas or even ginger ale won’t work for this!

3. Trim Stems Daily

Keeping stems fresh ensures they can most effectively absorb water. Stems should be trimmed at least half an inch when they first come home with sharp, clean clippers and plopped back in the water immediately. Once cut, the stems will begin to seal up. “Delaying putting them in the vase will inhibit their ability to hydrate properly,” Stembel warns.

4. Keep Flowers in a Cool Location

Keeping your flowers out of extreme conditions (like super-hot window sills) will prevent them from dying faster and creating build up and bacteria in the vase. Most flowers prefer cool, shady spots, so keep them away from the radiator in the winter, too.

5. Change the Water Daily

Just like humans, flowers don’t thrive when they’re drinking stagnant, dirty water. Daily water changes flush out any bacteria that flowers are sitting in, and they also eliminate any odor that comes with rotting plants.

6. Remove Any Stems as They Die

Pruning dead stems will remove sources of excessive bacteria since decaying flowers release bacteria into the water faster than fresh stems. You should also remove any leaves that fall below the waterline each time you change the water.

7. Clean Your Vase

It’s important to do this after removing a dying bouquet to make way for a new one. A lot of people don’t consider the bacteria that can be in the vase before the bouquet goes in. A good rinse with warm water and soap will make sure the flowers have a clean start.

I also make sure that no leaves are submerged in water, only clean stems.

7UP instead of water. Replenish as necessary.

I’ve been putting a penny in the vase I put tulips in - it keeps them from drooping

Some flowers just don't last long, no matter what's added to the water or how carefully they are cut or stored. Hollow stemmed flowers like daffodils and tulips tend to last longer than thin stemmed roses for instance. Tulips will actually grow once cut!

I usually clean my vase with a little bleach and water (possibly, some Dawn too) before using it. Then I dump out the liquid. If I do not have the commercial flower food, I add a little sugar to the water before arranging the flowers in the vase. I also remove leaves from the stems and cut them on a diagonal. I try to replace water every other day or so as needed. I remove excess foliage from the water to avoid bacteria from forming. As flowers die, I try to save the ones that still look good and put them in smaller vases if necessary. For me, there is nothing like having fresh flowers in the house! A tip that my friend gave me after we made holiday arrangements of greens using the wet floral foam: use a turkey baster to water the arrangement. It works like a charm!

It's dangerous to mix bleach & vinegar

Bleach + Vinegar = Chlorine gas

Thanks for pointing this out!

I also change the water every day and remove any stems. My husband very often orders for me so beautiful flowers bouquets from https://flowershopn5.com/collections/bouquet. I like this flower shop.

Bleach + Vinegar
The combination sounds like it'd be a powerful disinfectant, but the two should never be mixed. "Together, they produce chlorine gas, which even at low levels, can cause coughing, breathing problems, and burning, watery eyes

Most put lemon or lime juice where she put vinegar. A simple edit that perhaps she could do? The 😊

It's mixing bleach and ammonia that create chlorine gas not vinegar. It is very dangerous even small amounts can respatory distress. Please be informed and very careful when mixing chemicals.

Nope.. bleach + ammonia create chloramine gas (not chlorine gas)

Bleach + Vinegar = Chlorine gas
"Mixing bleach and vinegar is a bad idea. When you mix these two substances, toxic chlorine gas is released"

Bleach + ammonia = Chloramine gas
"Mixing products containing chlorine bleach with products containing ammonia releases chloramine gas"
https://www.healthline.com/health/bleach-and-ammonia

Maybe it's the similar look and sound of the words chloramine and chlorine that get people confused, but it's important to know the difference. Both are dangerous "Chlorine gas, however, causes more severe and long-lasting effects than chloramine gas" https://www.chop.edu/centers-programs/poison-control-center/household-cleaners

Chlorine and chloramine are very similar words. If you don't have a PhD in chemistry, you may very well think they're the same thing, and truth be told, they're pretty similar in many regards. https://vortexpure.com/blogs/news/the-difference-between-chlorine-and-chloramine-and-why-is-it-important

Lemon and lime juice are also acids (like vinegar) so will produce the same reaction

i add a few ice cubes to tulips everyday and it makes them stay together and upright longer.

Also, I was cleaning the stains out of my mum's china cups today and I read that the combination of vinaegar and bleach can produce a rather harmful chlorine gas....yikes....does anyone have more info here?
 
GigiR May 11, 2020
Hi Alistair. Just passing on my Mum’s tip for cleaning china cups and teapot: moisten cup etc with water, then use baking soda and a clean cloth to remove the tea stains. Rinse well. Works for me.

Quite by accident, I discovered a way to make flowers last for weeks. Our cat thinks fresh flowers are snacks, so after waking up one too many times to a vase full of stems, I started putting the vase of flowers in the fridge at bedtime and whenever I left home. My anniversary flowers lasted for almost six (!!) weeks.
 
Erica D. July 28, 2020
Careful. Some plants are toxic to cats yikes.
 
FS May 10, 2022
Lilies are very toxic.

If you see your cut roses flopping over too soon, you can try the following. Position a cookie sheet or baking pan large enough to accommodate the length of the flowers. Put it in the sink or tub or even on the counter, wherever it can sit over night. Tilt the flat pan by putting something like a rolling pin or box of foil under and along one of the short sides. Fill it with cold water.
Trim all leaves off of the roses that might end up under water when they’re returned to the vase. Then, trim off about 2-3” from the bottoms of the stems, one at a time. Immediately plunge the stem in the cold water on the tray. Lay it down in the tray, so the flower is higher than the stem end. If the roses are not too far gone, the flower should be upright by the next day, if not sooner. You’ve trimmed off the part of stem with the air lock in it and the bloom will continue to drink water. Vase it up.

I agree with Andreus....the combination of bleach + vinegar could produce toxic fumes...especially if you're unwise enough to be standing over the container as you pour them in. One or t'other...not both.

I use a similar formula in a gallon of distilled water, cut stems and change water every couple of days. I keep carnations looking good for two weeks using this method. Also, using distilled water prevents hard water deposits on clear glass vases.

If you're changing the water on a daily basis, a gallon is not that much water.

The best two tips I learned for cut flowers:
1. Heat is the enemy. Or, there's a reason why florests keep their flowers in refrigerators. If you don't have space to put your flowers in your refrigerator overnight, take them outdoors and bring them back inside the next morning. I've actually seen tulips close back up overnight.

2. Neuter your blossoms from bulbs. The minute you can reach inside a lily (or tulip or ....) pick off the stamen.

Bleach = base
Vinegar = acid
Base + acid = zilch, nada, nope
Highschool much?
Junk science is ruining the world, one stupid article at a time.
 
isw September 1, 2018
Um, with a pH of about 12, bleach is most certainly NOT an acid.
 
BerryBaby August 31, 2018
I don't add anything to the water. I cut the ends and put them in cool water and change the water every few days they last for at least 10 days.
 
Anne T. August 31, 2018
Thank you. Was using warm water, changing every day, cutting ends on the diagonal also every day. Lucky when blooms lasted five days,

Any tips for hydrangeas?
 
BerryBaby August 31, 2018
Unfortunately they realky aren't a cutting flower. I dry them in the garage, hand them upside down. They are beautiful in a fall arangement.
 
Merry September 1, 2018
A friend in the flower business says hydrangeas take in water through their petals and to mist them daily to keep them fresh. If they start to wilt, dunk the whole head in warm water for a few minutes.
 
Rebecca April 25, 2019
If you dip the stems of a hydrangea in alum they won't wilt. Best tip ever! I have tried it with lilacs too and it also works.
 
Anne T. April 25, 2019
Alum...where would I buy? Thanks for the great tip. It’s lilac season.
 
Patti D. April 26, 2020
If they are hopelessly droopy, cut the stems quite short and either mist heavily or dip in water. 9/10 times they bounce back in a few hours.
 
FoodFreak April 28, 2020
This was suggested by another customer of the farmers market stand where I buy flowers and it seems to work: dip the freshly trimmed stem of the flower in boiling water for ten seconds, being careful not to let any steam touch the flower, and then put the stem into your vase of cool water. It seems to give them another few days unless it is high summer, when they don’t keep for more than a day or two.

I have also been told to strip the stems of hydrangeas of their leaves - maybe leave one or two at top as they take in much water and thus blossoms get short changed and wilt...! This really has worked for me. Also I do cut stems, dip in hot water for maybe 30 sec. and then smash the woody stem to help water rise into the stems...lots of TLC but taking the leaves off is really the trick...

Great article! - right to the point - also I like your scaled down receipe - who wants to make a gallon 🌺
