Many people receive Valentine’s Day gifts from loved ones, especially roses, but they decline shortly after Feb. 14. Kansas State University horticulture expert, Cynthia Domenghini offers guidelines to extend the life of floral arrangements and loose stems. 

“For floral arrangements, keep the vase filled or floral foam soaked with warm water,” Domenghini said. “Add fresh, warm water daily and if the water turns cloudy, replace it immediately.” 

Domenghini suggests recutting loose stems every time water is replaced by removing 1-2 inches with a sharp knife, under water to allow the stem to draw water instead of air. 

“Keep flowers in a cool spot (65 to 72 degrees Fahrenheit), away from direct sunlight, heating or cooling vents, directly under ceiling fans, or near radiators,” Domenghini said. 

For loose stems, begin by filling a clean, deep vase with water and add the flower food obtained from your florist. 

“Remove leaves that will be below the waterline. Leaves in water will promote bacterial growth,” Domenghini said, “Stems should be cut immediately before putting them in water.” 

If you cannot get flowers in a food solution right away, keep them cool, Domenghini added.
