How to Keep Summer Flowers Looking Beautiful for Longer

August 11, 2026

Summer flowers have a habit of doing their own thing!

Hydrangeas drink astonishing amounts of water. Roses slowly loosen and open. Delicate meadow flowers that almost disappear amongst a new bouquet can suddenly become the stars of the vase a few days later. Even the grasses seem determined to wander in their own direction. That is part of what we love about summer flowers. Here are our florists’ summer flower care tips to help you get the very best from every stem.

Warm days do mean your bouquet needs a little more attention, though. Sunny windowsills, warmer rooms and thirsty stems can all affect how flowers behave once you get them home.

So, rather than a long list of flower-care rules, here are the things our florists actually do with fresh flowers every day – and a few tricks worth borrowing for your own flowers at home.

What Should You Do When Your Flowers First Arrive?

First, find the vase. Give it a proper wash before filling it with fresh water. A vase that looks clean isn’t always as clean as you think, particularly if it has recently held another bunch of flowers. Next, unwrap your bouquet and take a look at the stems. Remove any leaves that will sit below the water line and give the bottom of every stem a fresh cut with clean, sharp scissors or secateurs. Then comes the enjoyable bit. Don’t feel that you have to recreate exactly how your florist was holding the bouquet. Once the flowers are yours, arrange them to suit your home. Let a beautiful rose come forward. Give an unusual flower a little more room. Allow grasses to sit higher and foliage to escape around the edges.

Everything you need to create your own beautiful floral arrangement, including hand-selected seasonal flowers, a glass vase, florist scissors and natural twine.

How Often Should You Change Flower Water in Summer?

Our easiest piece of summer flower care advice is also one of the simplest: Every time you walk past your flowers, look at the water.

A generous summer bouquet can drink a surprising amount, particularly when it contains thirsty flowers such as hydrangeas. Top the vase up whenever the water level drops and aim to replace the water completely every couple of days. If it starts looking cloudy before then, change it sooner. When you do change the water, give the vase a rinse too. You can also give the stems another small trim before putting them back.

It only takes a few minutes, but fresh, clean water can make a real difference during warmer weather.

Where Should You Place Flowers During Hot Weather?

Possibly not where they look best. That sunny kitchen windowsill might be perfect for photographing your new bouquet, but strong sunlight and heat can encourage cut flowers to develop and fade more quickly. Instead, find somewhere bright but away from direct summer sunshine and other sources of heat.

And when temperatures really climb, try one of our favourite tricks:

Move your flowers into the coolest room in the house overnight.

They won’t mind missing the view. If you’re going away for a summer weekend, change the water before you leave, remove anything that’s beginning to fade and leave the arrangement somewhere cool with plenty to drink.

What Is the Best Vase for Flowers in Warm Weather?

The prettiest vase isn’t necessarily the best vase for the flowers you’ve brought home. Start with the size of your bouquet.

A large, loose arrangement needs enough room for its stems. If you’re forcing everything through a narrow neck, reach for something wider.

For a smaller collection of flowers, however, a vase with a narrower opening can be brilliant. It naturally supports the stems and makes a handful of flowers look beautifully arranged without much effort.

Height matters too. Tall or heavier stems need enough support, while shorter meadow-style flowers can look wonderful in something lower.

Whatever you choose, start with a really clean vase and plenty of fresh water.

If you enjoy arranging flowers yourself, take a look at our Vases & Bottles collection for different shapes and sizes to experiment with.

Do Larger Vases Help Flowers Last Longer?

Not necessarily, but the right-sized vase certainly helps.

A large bouquet can contain a surprising number of stems. Pack all of them tightly into a small vase and there is less room for water, while the flowers can also lose the loose shape that made you fall in love with them. A more generous vase provides a larger reservoir of water and gives the stems room to sit naturally. But bigger isn’t automatically better.

A small arrangement swimming around in an enormous vase won’t look particularly happy either. Choose a vase that supports the flowers while allowing them enough room to move. And remember – a huge vase filled with old water isn’t going to do your flowers any favours.

Fresh water and a clean vase still win.

Which Flowers Last Longest in Summer?

This is one of those questions where our florists will often answer:

It depends on what’s looking fabulous that week.

Some cut flowers naturally have a longer vase life than others. Chrysanthemums, carnations and alstroemeria can be wonderfully long-lasting, as can many types of foliage. Other delicate summer flowers may have a shorter moment. But we don’t think that means you should choose flowers purely according to which will last the longest.

Part of the pleasure of seasonal flowers is enjoying something while it’s here.

A beautiful summer bouquet will often contain flowers at different stages. One variety may finish while another is only just opening, so the arrangement gradually changes rather than simply reaching an end.

How Do You Look After Hydrangeas in Summer?

Hydrangeas deserve a section of their own. A huge hydrangea can look magnificent at breakfast and thoroughly unimpressed with life by teatime. Usually, it’s thirsty. Those enormous flower heads need plenty of water, so pay particular attention to the water level if your bouquet contains hydrangeas. If one begins to droop, don’t immediately give up on it. Give the stem another clean cut and return it to plenty of fresh water. We’ve seen many apparently defeated hydrangeas stage surprisingly impressive comebacks.

Should You Keep Fresh Flowers Away From Fruit?

Yes, if you can. Flowers on the kitchen table beside a bowl overflowing with summer fruit may look lovely, but they’re not necessarily ideal neighbours. Ripening fruit releases ethylene, which can encourage cut flowers to age more quickly.

You certainly don’t need to banish the bananas to another room. Just avoid positioning your fresh flowers immediately beside the fruit bowl.

What Should You Do When Some Flowers Start to Fade?

Don’t throw the whole bouquet away!

This is probably one of our favourite flower-care tips. Different flowers have different vase lives, so it’s perfectly normal for one or two stems to finish before everything else. Take those flowers out and look again at what’s left. Give the remaining stems another trim, change the water and rearrange them. Your large bouquet might become a smaller arrangement.

A few days later, that arrangement might become three little bud vases. Our collection of Pretty Bud Vases is perfect for giving those last beautiful stems a new place to shine.

Eventually you might have one fabulous rose, a stem of eucalyptus and a couple of grasses sitting on the kitchen windowsill. That’s not a bouquet that’s finished, it’s simply the next version of it.

Give the Last Few Flowers a Vase of Their Own

The final stems are often the most fun. A flower that almost disappeared amongst a large bouquet can look completely different when you give it a little vase of its own. Put one beside the bed. Place a couple along the dining table. Add one to a bathroom shelf. Or line several glass bottles along a windowsill and divide the remaining flowers between them.

It’s also why we love Bud Vases & Bottles. They’re brilliant for enjoying the last beautiful stems rather than throwing away an entire arrangement because some of the flowers have finished.

One Last Florist Trick

Once you’ve arranged your flowers, stand back and look at them. Then turn the vase around. You’d be surprised how often the most interesting side isn’t the one you originally intended to face the room. Pull one flower slightly forward. Let something taller escape from the outline. If a stem naturally bends in one direction, try working with it rather than fighting to straighten it. Flowers don’t need to sit at identical heights or form a perfect dome. In fact, we usually think they’re much more interesting when they don’t.

Enjoy Your Summer Flowers as They Change

Perhaps the best summer flower care advice we can give is not to expect fresh flowers to stay frozen in time.

Roses are supposed to open. Buds develop. Delicate flowers finish. Grasses move. Hydrangeas change. And sometimes the stem you barely noticed when the bouquet arrived becomes your favourite three days later.

Enjoy each stage.

Our florists work with the flowers arriving into our Marlow and Bourne End flower shops throughout the summer, choosing beautiful seasonal stems and putting them together with the individual eye of the florist creating the bouquet.

Once those flowers leave our hands, you get to make them yours.
