Should You Put Your Cut Flowers in Hot or Cold Water?

by Robert Canning on April 22, 2022

If you get flowers from a loved one or even buy fresh ones from your favorite florist for your home, you know that cut flowers need to be put in water for them to last longer.  

But what’s the ideal water temperature for your cut flowers? Read on and find out as your trusted florists in Dubai share some helpful information:

Ice Water

A common misconception among people is the impact of cold water temperature on blooming flowers. The idea is that living things need something cold and refreshing especially when it's hot. However, water temperature is not directly correlated to the flower’s temperature because it is the decrease in temperature that is responsible for the blossom's closing.

Also, cold water tends to keep the blooms closed longer. So if you want your flowers to blossom faster, stick with lukewarm water.

Warm Water

Warm water is ideal for flowers because it increases the flower’s metabolism and encourages the growth of the plant's cells. This can lead to earlier blooming and better growth of the flowers.

Warm water also encourages the flower to drink more and brings the hydrated oxygen to the flower's root systems, increasing the number of blooms.

The trick is to take the flowers out of the delivery box and let them sit in the room for about 15 minutes before you put them in water. Put the flowers in the lukewarm water and make sure the water covers the stems.

Extremely Hot Water

If you want to open the flowers, you may try hot water as this tends to make the petals open faster. The temperature of the water should be around 140 degrees Fahrenheit. 

However, this is not good for the plants as it might dry out the stem and close the flower. Also, too much moisture can lead to water-borne diseases. 

So, What's the Ideal Temperature for Cut Flowers?

The ideal water temperature for your cut flowers depends on the type of flower.

Carnations and roses need water that is warm but not too hot.

Cut tulips, hyacinths, and lilies need lukewarm to cold water.

Hydrangeas need water that is at room temperature.

The water temperature for blooming paperwhites and other tropical flowers should be warm.

Tips to Keep Your Flowers Fresh

Now that you know more about the ideal water temperature to use for your cut flowers, here are some other tips that can help you keep your blooms fresher, longer:

Follow the Right Watering Schedule

Keep your flowers extremely well-hydrated and the color will remain vibrant for a longer period. Don’t forget to check the water level every day.

Remove Petals to Extend Flowers' Life

Petals are the most delicate part of a flower. Use tweezers or carefully pull them away to extend the flowers' life.

Freeze in Ice Cubes

Fill a plastic bag with water and ice cubes, place the flower inside, and seal it. The ice cubes are great for keeping the flowers fresh for a long time.

Add Clear Tape on the Vase's Bottom

The tape will help in the better arrangement of the flowers while keeping the flowers in place. It will also prevent the water from spilling.

Change the Water Daily

Change the water every morning to ensure the freshness of the flowers.


Using the right water temperature is an integral part of keeping your flowers fresh for longer. We hope you found this guide on the ideal water temperature for cut flowers helpful. If you wish to know more about taking care of your flowers, you can contact your favorite floral shop for more tips!
