Learn simple tricks to extend the life of cut flowers! Discover how to make flowers last longer in a vase and keep your bouquets beautiful.
Whether you grow your own flowers to cut or pick them up at the local market, there’s nothing quite like a beautiful bouquet of fresh flowers. But keeping fresh-cut flowers alive longer in a vase isn’t always easy – even for a experienced gardener like myself.
While I’ve been growing beautiful flower gardens throughout my landscape for over 25 years, I was not cutting much of the blooms to enjoy indoors. Isn’t that crazy?
I chose not to cut a lot because I grow several different plant varieties on half an acre of property. This might sound like a lot, but because there are so many different plants, I always enjoyed them more IN my garden rather than inside my home.
But through the years, I changed my tune and decided to focus more on growing flowers that are better for cutting. As I’ve been cutting and making arrangements, I’ve researched and learned how to make fresh flowers last longer in a vase. So today, I’m sharing all my best tips for making your own cut flower arrangements last indoors.
So stop throwing away your blooms and follow these simple tips to extend their vase life.

Growing Cut Flowers for Vase Arrangements
A few years ago, I started growing dahlias. And they truly stole my heart! There are so many different unique varieties to grow. They make a great late summer/early fall addition to the cottage garden but also look incredible in a vase.
Because I loved growing dahlias so much, I decided to start seeds indoors to expand my flower beds for cutting. I grew well over 1000 flowers indoors that are not readily available at local nurseries. It was the best!!!! Some of the flowers I grow from seed include:
- Zinnias
- Snapdragons
- Cosmos
- Strawflowers
- Larkspur
- Sweet Peas
- Calendula
- Tithonia
- Celosia
- Gomphrena
- Sunflowers
- And so many more.
You can often find me outside cutting flowers to make new arrangements, bouquets, and centerpieces for myself, family, and friends. But it’s been pure joy to play with flowers all season long.
As I’ve been making several bouquets, I’ve learned a few good tips to prolong the life of fresh-cut flowers. Keep reading for my best tips on how to make fresh flowers last longer.
How Long Can You Keep Cut Flowers Fresh in a Vase?
The lifespan of flowers in a vase can vary depending on the type of flower, its freshness when cut, and the care it receives in the vase. However, in general, most cut flowers can last for around 5-7 days in a vase if properly cared for.
Some varieties, such as roses, lilies, and chrysanthemums, may last longer than others, while more delicate flowers, like tulips and daffodils, may not last as long. That said, there are things we can do to help prolong the life of flowers in an arrangement.
How to Make Flowers Last Longer in a Vase
There’s nothing like a beautiful arrangement of fresh-cut flowers, am I right? I wish they’d last longer than they do. Flowers make people happy and if you get a bouquet on a special occasion or you cut them from your garden, you want them to last as long as possible.
Follow these tips to keep flowers fresher for longer.
Always Start With a Clean Vase or Floral Foam
To eliminate harmful bacteria, always clean your vase or container vessel with 1 part bleach to 10 parts water. And if you are using floral foam? Don’t re-use it.
I know it might seem more economical to get a few uses out of it, but the flowers DO NOT APPRECIATE the economics as much as we do. So always start with fresh blocks. If you want to cut down on costs, cut the blocks down to a minimum size for use. THESE are the floral foam blocks I’ve been using.

Prepare Each Flower for the Arrangement
Preparing flowers for an arrangement involves a few key steps to ensure that they are fresh, hydrated, and ready to be arranged. Before making a fresh flower arrangement, it’s important to prepare the flowers before dropping them in a vase.
If you are cutting your own flowers, start with the freshest flowers you can find. Look for flowers that are just starting to open, with sturdy stems and bright, vibrant colors.
Remove Foliage Before Arranging
Remove any leaves or thorns from the lower part of the stems that will be submerged in water. This will help prevent bacteria growth and keep the water clean. I recommend removing most of the lower leaves while you’re picking the flowers outdoors to make the job of arranging them easier.

How to Re-Cut the Stems
A great way to prepare them is to re-cut the stems so they can absorb water and nutrients more easily.
- When cutting your own flowers, always cut them at a 45-degree angle. Cutting them at a 45-degree angle keeps them from sitting flat and promotes better water consumption.
- Drop fresh cuts immediately in room temperature water.
- Remove all leaves and lower stems that will sit in any water. Anything left under the waterline will rot and cause the flowers to prematurely decline in the arrangement.
- If some time elapsed after cutting your blooms, I make a second fresh cut on a 45-degree angle just before I drop it in the arrangement.
- Tip: whenever you are cutting flowers, make sure you clean your snips in between varieties so you don’t pass any problems to other plants.
Cutting the stems at an angle with a sharp knife or scissors can help to create a larger surface area for water uptake, allowing the flowers to absorb more water and nutrients. This can help to keep the flowers hydrated and healthy, which can improve their longevity and overall appearance.

Condition The Flowers
It’s a good idea to make sure your flowers are super hydrated before arranging them. Submerge the stems most of the way in a bucket of warm water containing flower food. Place the bucket in a cool, dark location like a basement or garage for a few hours or as long as overnight before arranging the flowers.
Feeding Fresh-Cut Flowers to Prolong Their Vase Life
To extend the vase life of a flower arrangement, it’s important to feed the bouquet. Cut flower food provides a great source of nutrition for centerpieces, bouquets, and flower arrangements.
First, flower food provides essential nutrients that help to nourish the flowers and prolong their lifespan. These nutrients include sugars to provide energy for the flowers, citric acid to regulate the pH of the water, and bleach to prevent the growth of bacteria that can clog the stem and cause the flowers to wilt.
Second, flower food also contains ingredients that help to keep the water clean and clear, which can help prevent the growth of bacteria and fungi that can damage the flowers. Lastly, flower food can help improve the overall quality and appearance of the flowers, promoting vibrant colors, strong stems, and healthy foliage.
Thus, using flower food can significantly improve the longevity and beauty of fresh-cut flowers in a vase, making it an important step in caring for them.
How to Make Homemade Flower Food
If your arrangement didn’t come with flower food or you don’t want to buy your own, you can easily DIY a cut flower food recipe. There are lots of different recipes out there to try, for years I was using 2 aspirins, 1 teaspoon of sugar, and a few drops of chlorine bleach (to kill harmful bacteria). But now I use this homemade flower food recipe.
It is harder to feed fresh-cut flowers if they are sitting in floral foam, so I use that formula per quart of water when watering the blooms. This method seems to help.
Keep the Water Clean
Changing the water in a vase is important to keep flowers fresh longer because stale or contaminated water can cause bacteria to grow in the vase. This bacteria can clog the stems of the flowers, preventing them from absorbing water properly and causing them to wilt more quickly.
By changing the water in the vase every 2-3 days, you can help prevent the growth of bacteria and keep the water fresh and clean. This ensures that the flowers have a consistent supply of clean water and nutrients, which can improve their lifespan and overall appearance.
In addition to changing the water, it’s also important to clean the vase thoroughly before refilling it again to prevent any bacteria or debris from contaminating the new water.
An important note about watering though. Do not use hot water because it’s not good for the flowers. Room-temperature water is best.
Keep the Flowers Cool
There’s a reason florists typically store cut flowers in a refrigerated space – a cooler space can help flowers stay fresh for longer. While you probably don’t want to keep your flowers in an actual fridge (you want to be able to admire them!), arrangements will last longer if you keep them away from direct sunlight and heat and move to a cooler place overnight.
Re-cut Stems When You Change the Water
When you change the water of your fresh flower arrangement, it’s a good idea to recut the stems because, over time, the ends can become clogged with bacteria and air bubbles, which can prevent the flowers from absorbing water and nutrients properly.
By recutting the stems, you remove any blockages and create a fresh surface area for water absorption, which can help to extend the life of the flowers.
When recutting the stems, it’s important to cut them at a 45-degree angle, which can help to prevent the ends of the stems from resting flat against the bottom of the vase and obstructing water uptake.
Remove Wilted Blooms and Petals
As your fresh flower arrangement ages, it’s a good idea to remove any wilted flowers or foliage that looks brown, saggy, or otherwise unhealthy. Wilted flowers and petals can cause bacterial growth and decay, which can spread to the other flowers and shorten the lifespan of the arrangement.
As flowers age and wilt, they begin to produce bacteria that can clog the stems and prevent the flowers from absorbing water and nutrients. This can cause the flowers to wilt and die more quickly. Not to mention, it can also lead to an unpleasant odor and slimy water in the vase.
By removing the flowers and foliage that are no longer healthy, you can help prevent bacterial growth and ensure that the remaining flowers stay healthy and hydrated.
Additionally, removing wilted flowers and petals can help improve the overall appearance of the arrangement. Removing them can help the remaining flowers stand out and create a more vibrant and visually appealing arrangement.
But that depends on the types of flowers you have because some look more beautiful as they take on a more vintage look. So depending on the aesthetic you want, you may or may not want to remove flowers that become faded or discolored. Just understand that leaving them can impact the vase life of the more vibrant blooms.
Keep Fresh Flowers Out of Direct Sunlight
It is important to keep fresh-cut flowers out of direct sunlight because the heat and UV rays from the sun can cause the flowers to wilt and dry out more quickly. The heat can cause the flowers to lose moisture through transpiration, while the UV rays can damage the pigments in the flowers, causing them to fade or discolor.
Additionally, direct sunlight can cause the water in the vase to become too warm, which can stimulate bacterial growth and further shorten the lifespan of the flowers.
To keep your flowers fresh and healthy for as long as possible, it’s best to place them in a cool, shaded area away from direct sunlight, heat sources, and drafts. This will help to slow down the aging process of the flowers and maintain their vibrant colors and delicate beauty.
I also suggest putting them in a location where if it leaks any water, you won’t damage anything. Or you can use something like THIS or THIS under your arrangement, depending on how fancy you want to get.
Avoid Heat, Drafts, and Fresh Fruit
Sunlight isn’t the only thing to avoid if you want to keep fresh flowers longer. Extreme temperature changes and even fresh fruit can impact their longevity.
Don’t display your arrangements near appliances that generate heat (such as a heating vent) and avoid areas that could be cold and drafty too, such as next to open windows or under ceiling fans.
Believe it or not, storing fresh flower arrangements next to fresh fruit can also impact their lifespan. Ripening fruits release tiny amounts of ethylene gas, which can make your fresh flowers wilt faster.
Avoid Grouping Certain Flowers Together in a Vase
Pairing flowers in a vase is a bit like creating a little community where everyone needs to get along, but not all flowers play nice together! Here are a few pairings you might want to avoid and why:
- Daffodils with Anything Else: Daffodils are lovely on their own, but they’re a bit of a diva in the flower world. They secrete a sap that can clog the stems of other flowers, preventing them from taking up water. If you’re dead set on mixing them, let the daffodils sit in water by themselves for a day, then change the water before adding other flowers.
- Tulips and Daffodils: Tulips also don’t mix well with daffodils for the same reason. The sap from daffodils can harm tulips, so it’s best to keep them in separate vases.
- Carnations and Gardenias: Carnations, while hardy and long-lasting, can release a substance that shortens the vase life of more delicate flowers like gardenias.
- Lilies: Lilies have a strong scent that can overpower the fragrance of other flowers. If you’re looking to create a bouquet with a balanced aroma, you might want to keep strongly scented flowers separate.
- Hyacinths: Their strong scent and heavy pollen can overpower other flowers in a mixed arrangement.
- Poppies: Similar to daffodils, poppies release a sap that can shorten the vase life of other flowers.
The key reason behind these incompatibilities usually boils down to different flowers having different water needs, releasing substances harmful to each other, or simply overpowering each other in scent.
Always consider the water requirements and chemical compatibilities when grouping flowers together. Mixing and matching flowers can be a fun experiment, but knowing these basic compatibilities can help you create combinations that are both beautiful and long-lasting!
Do Those Flower-Preserving Tricks Actually Work?
If you search online for ways to extend the life of your cut flowers, you’ll find an abundance of advice. Everything from specific water additives to handling techniques. But do any of these tricks really make a difference?
I’ve shared some common recommendations above, and while they can be helpful, remember that different flowers have unique needs. It’s always best to research the specific care requirements of the blooms you’re working with.
Let’s delve into one popular suggestion:
Vinegar in the Vase: Yay or Nay?
You’ll often find recommendations to add vinegar to the vase water. The idea is that its acidity helps curb bacterial and fungal growth, potentially benefiting the flowers.
However, some professional florists often advise against this method because they say the acidity can actually harm delicate blooms.
That said, gardening is all about experimentation! If you’re curious, you could add 1-2 tablespoons of white vinegar per quart of water, along with some sugar for nutrients. Just be mindful that different flowers may react differently.
Does Sugar Make Flowers Last Longer?
Yes, sugar can indeed extend the vase life of flowers. It provides a source of energy, helping them stay vibrant and encouraging blooms to open fully. That’s why I always include it in my homemade flower food recipe.
Typically, 1-2 tablespoons of sugar per quart of water is sufficient. Make sure to dissolve it completely.
Baking Soda in the Bouquet: Helpful or Hype?
You might encounter suggestions to add baking soda to vase water. It’s thought to neutralize the water’s pH, preventing it from being too acidic or alkaline.
While this can offer some benefit, you’re likely better off focusing on providing nutrients with sugar and changing the water frequently to maintain freshness. Baking soda’s probably more useful in your kitchen than your vase!
The Penny Trick: Old Wives’ Tale or Legit Tip?
Putting a penny in the vase is an old trick based on the idea that copper acts as a fungicide. The penny should be dated before 1981, as those were made with more copper.
However, the effectiveness of this is debatable. While some swear by it, prioritizing good flower food and fresh water is generally more reliable.
As a personal note, I’ve found the penny trick helpful with tulips, keeping their stems upright.
Should you put flowers in warm or cold water?
It depends! I typically recommend putting cut flowers in room-temperature water. Warm water helps to facilitate the uptake of water and nutrients by the flowers by easing the flow of water through the stems. But it’s important to make sure your water is not too hot or you’ll risk damaging the flowers. Room temperature water or just slightly warmer is usually best.
However, some flowers do better in cold water (such as tulips) so be sure to research each individual flower’s needs and adjust accordingly.
Why is bleach good for flowers?
Bleach can be used in small amounts in vase water because it can help stop the growth of bacteria and fungi, which can clog the flower’s vascular system and lead to a shorter lifespan for the blooms. I like to add a small amount of bleach to my DIY flower food.
Can I use tap water for flowers?
You can use tap water for flowers in most cases. However, the quality of tap water can vary depending on your location. Some tap water can contain minerals, chlorine, fluoride, and other substances that could impact the health and longevity of cut flowers, so I recommend doing some research into your local water or using filtered water for your vase flowers.
