How to care for sunflowers in a vase?

To ensure you have the longest lasting blooms, always buy fresh cut sunflowers or grow your own in a cut flower garden and put them in water as soon as possible. Here’s how to make sure they last as long as possible.

1. Trim the stems

“Cut thick stems at an angle with sharp pruners,” suggests florist Sue Fogwell. A clean cut ensures that you don’t pinch the water-conducting vessels in the flower stem.

“This allows the flowers to absorb as much water as possible and ensures that they don’t sit on standing water which could cause them to rot,” adds Simon de GrowYourYard.com (opens in a new tab).

2. Add lukewarm water to your vase.

Be sure to clean your vase before putting your sunflowers in it by washing it with water. “Once home, immediately place the flowers in a vase of warm to cool water prepared with a floral preservative,” advises Sue Fogwell. Hot water is more quickly absorbed by the flowers than cold water, which will help prevent your sunflowers from wilting.

3. Change the water

“Change the water every other day – more often if the water gets cloudy,” suggests Nancy White, floral designer and owner of The Flower Bar (opens in a new tab) in Larchmont, NY. ‘Clean the vase before filling it with fresh water to eliminate any bacteria.’ Other florists suggest changing the water daily.

“Prune the stems daily at an angle while giving the flowers fresh water,” adds Sue Fogwell, “as well as a cool preservative.”

4. Add sugar and lemon to the vase

“Add sugar and lemon to the vase to keep the sunflowers fresh and blooming,” suggests Jason White, CEO of All about gardening (opens in a new tab). “A teaspoon of sugar to two tablespoons of lemon juice or a tablespoon of vinegar would make a pretty good mix. This will delay the rapid wilting of your cut sunflowers.

5. Place out of direct sunlight

“Place your sunflower’s vase in an area where direct sunlight can’t reach it,” adds Jason. “Unlike planted sunflowers, cut sunflowers don’t like sun exposure as much.” You should also avoid placing sunflowers near heat sources or in cool drafts, such as air conditioning.
