You've just received a beautiful bouquet and the flowers look stunning in your vase. But after about a week, you notice the first signs of deterioration: drooping leaves, brown edges and wilting flowers. Why does this happen? More importantly, can you do anything about it?

Many people are curious about why some flowers remain beautiful for weeks while others wilt after just three days. The answer lies in the fascinating interplay of biology, chemistry and natural processes occurring within every stem and petal.

Why flowers wilt

Wilting isn't necessarily a sign that something is wrong. It's simply part of a flower's natural lifespan. Each flower has a predetermined lifespan that is hardwired into its genes.

Some flowers, like roses, have a relatively long lifespan. Other flowers, such as tulips, have a naturally shorter lifespan. This is why you can enjoy a rose for up to two weeks, while a tulip wilts after just five days.

In nature, every flower has a specific function: to attract insects for pollination. Once this mission is accomplished, the flower has achieved its evolutionary purpose and begins to wilt. It's as if the flower is saying, 'My work is done!'

The Role of Energy: The choices flowers make

Plants must constantly decide how to allocate their energy. Once a flower has finished blooming, the plant has two options: it can put all its energy into producing seeds, which will later become new plants, or it can use that energy to produce new flowers.

You may recognise this process from the plants in your garden: if you leave a wilted flower on the plant, you will often see a small seed pod or seed ball growing where the flower once was. This process is costly in terms of energy, as it means that energy can no longer be diverted to new flowers.

This is why removing spent flowers is a smart move. By cutting off wilted flowers, you prevent the plant from producing seeds. Instead, all the plant's energy goes to new flower buds. It's as if you're telling the plant, "Forget about producing seeds; focus on producing more beautiful flowers!"

Water is crucial for the health of your flowers

As flowers consist of around 90% water, any disruption to their water supply has an immediate effect. As soon as a flower is cut, it becomes a race against time. It must maintain all its vital functions without the support of roots.

Air bubbles in the stem can block the water supply. When you cut a stem, air bubbles can enter the vascular bundles and act as a kind of plug. This is why a flower can suddenly droop, even if there is enough water in the vase. This is why we always recommend cutting stems diagonally with a sharp knife.

Bacterial growth is the biggest enemy of cut flowers. Dirty water provides an ideal breeding ground for bacteria that can clog the stem. These microorganisms form a biofilm that prevents water from reaching the flower. This is why we at De Duinroos recommend changing the water and cleaning the vase thoroughly every two days.

Evaporation through the leaves is a natural process that continues constantly. In a warm room or near a heater, this process happens much faster, causing the flower to dry out. Interestingly, flowers don't have the ability to adjust their breathing like plants in the ground do.

Hormones and temperature: The invisible factors

Flowers have their own hormone system. The hormone ethylene triggers wilting. Interestingly, ripening fruit also produces ethylene. Therefore, we recommend never placing flowers next to a fruit bowl!

Temperature has a significant impact on how quickly flowers wilt. At higher temperatures, all processes occur more quickly. This is why flowers stay beautiful for much longer in a cool room (around 15–18 °C).

Practical tips to prevent wilting

Now that you understand why flowers wilt, you can do more to prevent it. For more detailed advice, check out our care tips page!

• Choose flowers whose buds are not yet fully open.
• Make sure they have firm, green stems without brown spots.
• Cut the stems diagonally using a sharp knife.
• Always use flower food.
• Never place flowers near fruit or a radiator.
• Change the water every other day and recut the stems.
• Remove any wilted flowers immediately.
• Remove any leaves hanging in the water.
• Thoroughly clean the vase between bouquets.

Remember that each flower is unique

Not all flowers wilt in the same way. Gerbera daisies have a shorter lifespan than roses, but they retain their colour for longer. Lilies drop pollen and chrysanthemums droop. At De Duinroos, we therefore combine flowers with similar lifespans in our field bouquets.

Despite proper care, sometimes flowers wilt. This may be due to their naturally short lifespan, stress during transport or simply because some varieties are more delicate than others. Remember that cut flowers are a truly natural product. And nature is difficult to control!

You can slow down the wilting of your flowers

You can't stop wilting, but you can slow it down. By understanding the factors involved, such as hormones, bacteria, temperature and nutrients, you can give your flowers the best chance of staying beautiful for a long time.

Taking good care of your flowers can often mean enjoying your bouquet for days or even weeks longer. But what should you do if your flowers wilt too quickly? At De Duinroos, we always offer a 7-day vase guarantee on our flowers! If your bouquet wilts prematurely, we'll replace it.
