How to Keep Cut Flowers Fresh Longer

Initial Steps for Long-Lasting Bouquets

Start with a sparkling-clean vase. Recut stems immediately and plunge into water—delaying allows air to block water uptake. Cutting underwater (especially for roses) prevents air bubbles. Strip any leaves that would sit below the water line; they promote bacterial growth.

Care and Feeding

Use a commercial floral preservative—it acidifies water, inhibits microbes, and provides sucrose for energy. Home remedies (aspirin, vodka, soda) don't work. If you lack preservative, try this Brooklyn Botanic Garden recipe: 1 tsp sugar, 1 tsp bleach, 2 tsp lemon/lime juice per 2 quarts lukewarm water.

Place the bouquet in a cool spot (not freezing) overnight. Change water daily, recutting stems each time and removing spent blooms. Keep away from direct sun, heat, and ethylene-producing fruit like apples.
