How to Extend the Lifespan of Your Fresh Flowers, According to Professional Florists

1. Trim the Stems for a Longer Life

Christina Stembel, the founder and CEO of Farmgirl Flowers, shares that the key to flowers that last longer starts with healthy stems. As stems are prone to drying out during transportation, trimming them a couple of inches helps the blooms take in water more efficiently. Cut each stem at a 45-degree angle to increase the surface area, which helps the flowers absorb more water. For the best results, trim the stems under lukewarm (not hot) running water to ensure immediate hydration.

2. Trim the Lower Leaves Off the Stems

Megan Vejby, the floral designer for Scotts Flowers, suggests trimming or removing any leaves that fall below the water level in your vase. These leaves can introduce bacteria into the water, accelerating the decay of your flowers. By keeping the water clean and free from these leaves, you help your flowers remain fresh and smelling great.

3. Keep Away From Direct Light and Heat

Avoid the urge to place your bouquet near a window, as freshly cut flowers are quite sensitive to light. Stembel advises that flower arrangements should be kept out of direct sunlight and away from heat sources in order to stay well-hydrated. It's also best to keep them away from humid areas, as cut flowers thrive better in cooler conditions.

4. Replace Water Every Day

Changing the water in your flower arrangement regularly is another great way to maintain the freshness of your flowers. As flowers age, bacteria naturally build up, which can harm them. "To keep them hydrated and healthy," Stembel explains, "remove any sediment by refreshing the water and cleaning the vase if you notice any build-up at the bottom."

Wondering how much water to use? Stembel recommends filling your vase up to three-quarters with cool tap water before arranging your flowers. It's vital to replace and top up the water regularly for the best-looking blooms.

5. Pluck Wilted Flowers Out ASAP

If you spot a wilted flower in your arrangement, remove it from the bouquet as soon as possible. Like fresh produce, flowers emit ethylene gas, which can shorten the life of nearby blooms. To protect the health of your remaining flowers, simply remove the dying one and thank it for its time.

6. Keep the Flower Food Flowing (or Make Your Own)

Fresh flower bouquets typically come with a packet of flower food that can be mixed into the water in your vase. Make sure to stir it thoroughly. Replenish the flower food every two to three days when you change the water to keep your blooms vibrant.

If you're in a rush or tend to forget, a few drops of bleach can serve as a preservative. "Adding bleach to the vase slows the growth of bacteria, helping to extend the life of your flowers," Stembel suggests.

You can also create your own flower food. Sugar is often used to provide flowers with additional nutrients, helping them grow, but it should not be used by itself. Sugar promotes bacterial growth, so it’s best to combine it with a natural antibacterial agent like vinegar to maintain the flower's PH balance.

7. Remember Flower Longevity Varies

Different flowers have varying life expectancies. Each type of flower behaves differently, with some lasting longer or shorter once they’ve been cut and placed in a vase. For example, carnations tend to outlast peonies by quite a bit.

If you bought a pre-arranged bouquet from a local grocery store, it's possible the flowers were cut several days ago. As a result, their longevity may not be the same as flowers that were freshly cut at a florist.
