Warm Water
Florists often plunge new shipments of blooms into water that’s around 100-110°F. They then stash the flowers away in a cool area. The idea behind this process is that the warm stems are able to soak up a lot of water while the cool air up top keeps the blooms fresh. Of course, not every bouquet needs this type of treatment.
Ice Water
Some people insist that dunking their flowers into an icy cold bath is the best way to freshen them up. After all, if you’re feeling overheated and a bit droopy, a cool shower is a great way to refresh. There is some truth here. Stems often get dried out and develop air pockets during travel and storage.
Hot or Even Boiling Water
Some people assume that clogged stems can best be cleared by dipping them into some very hot water. While it’s true that hot water often breaks down blockages, it also destroys the stem tissue and encourages bacterial growth. Even worse, heat typically causes flowers to shed their petals more quickly.
Tips and Tricks
Now that you have a better understanding of the best water temperature for flowers, there are a few other tips and tricks to keep in mind when preparing your newly acquired bundle.
Keep Your Flowers Beautiful Longer
Dr. Helmenstine holds a Ph.D. in biomedical sciences and is a science writer, educator, and consultant. She has taught science courses at the high school, college, and graduate levels.
Preparing the Flowers
Start by discarding any decaying leaves or flowers. Trim the bottom ends of your flowers with a clean, sharp blade before arranging them in the vase containing the floral preservative. Cut the stems at an angle to increase the surface area for water absorption and to prevent the ends from resting flat on the bottom of the container.
The Water
In all cases, mix the floral preservative using warm water (100–110° F or 38–40° C) because it will move into the stems more effectively than cold water. Clean tap water will work, but if yours is very high in salts or fluorides, consider using distilled water instead. Chlorine in tap water is fine since it acts as a natural disinfectant.
More Tips
Trim away any foliage which would be below the water line. The wet leaves encourage microbial growth that can rot your flowers.

Soda
Don’t throw away those last drops of soda! Pour about 1/4 cup into the water in a vase full of cut flowers. The sugar in the soda will make the blossoms last longer. Note: If you have a clear vase and want the water to remain clear, use a clear soda, like Sprite or 7-Up.
Hair Spray
Just as it preserves your hairstyle, a spritz of hair spray can help your cut flowers look fresh longer. Stand a foot away from the bouquet and give them a quick spray, just on the undersides of the leaves and petals.
Apple Cider Vinegar
Everyone likes to keep cut flowers around as long as possible, and there are several good methods. One way is to mix 2 tablespoons apple cider vinegar and 2 tablespoons sugar with the vase water before adding the flowers. Be sure to change the water (with more vinegar and sugar, of course) every few days to enhance your flowers’ longevity.
Vodka
The secret to keeping cut flowers looking good as long as possible is to minimize the growth of bacteria in the water and to provide nourishment to replace what the flower would have gotten had it not been cut. Add a few drops of vodka (or any clear spirit) to the vase water for antibacterial action along with 1 teaspoon sugar.
Aspirin
It’s a tried-and-true way to keep roses and other cut flowers fresh longer: Put a crushed aspirin in the water before adding your flowers. Also, don’t forget to change the vase water every few days.
