Discovering the Best Method to Prolong the Life of Cut Flowers

Dry, parched flower petals look great in potpourri—but not so much when sticking out of a vase. Whether from a grocery store bundle or a fancy florist arrangement, colorful blooms can brighten living rooms for a fraction of the cost of a decorator. However, when stems droop and buds wither, the question arises: was it worth it? We tested common strategies to prolong the life of tulips, a popular yet temperamental flower, to find out what really works.

Our seven test bouquets started on the same note: each had its stems cut and was placed in identical vases on Day One. The vases contained 36 ounces of fresh, room-temperature water, and all except one also had an additive meant to boost longevity. As the week went on, the water level was kept constant. Here’s what we discovered:

1. **Aspirin**: It increases the water acidity, theoretically helping it move up the stem. Yet, the reality was disappointing—the flowers did not last.

2. **Mouthwash**: Known for killing bacteria, but its effect on flowers was unimpressive.

3. **Penny**: Copper, acting as a natural antibacterial agent, led to slow blooming and quick withering.

4. **Bleach**: Prevents mold, but while it maintains posture, the color faded fast.

5. **Clean Water**: Fewer bacteria meant beautiful initial blooms, but petals fell rapidly after the fourth day.

6. **Sugar**: Meant to mimic photosynthesis’ sugar rush, but it resulted in uneven blooming and splayed stems. Flowers, however, remained mostly intact.

7. **Flower Food**: Containing a biocide, acidifier, and sugar, it proved most effective, keeping the blooms nourished and fresh the longest, and available at florist shops.

In conclusion, flower food emerged as the clear winner. Additional reporting by Helena Hong.
