My bouquet trick costs just a few cents & will keep your flowers fresh longer – try a pre-1982 pro-tip for best results

A FAN of floral arrangements has spilled her secret to keeping her flowers fresh and lively.

She said looking before 1982 will give optimal results with any bouquet.

Amy (@amycurated) filmed herself demonstrating the advice in a video on TikTok.

She zoomed the camera in on a bouquet of red roses with Baby’s Breath.

At the bottom of the vase, there appeared to be pennies left inside with the water.

“PSA to the girlies,” read the text. “Keep your flowers fresh longer by putting pennies in their water.”

She also recommended being picky with the pennies being used for the hack.

“Use a penny made before 1982,” she added. “It’s majority copper.”

Amy was sure to explain why the copper-majority pennies made all the difference in the roses’ longevity.

“Copper is a fungicide, which naturally kills the bacteria that causes flowers to wilt,” she said.

“Pro tip, use a penny made before 1982 for the best effect,” she added.

According to the U.S. Mint, pennies were first manufactured as pure copper, but rising demand for copper during World War II led to changes in composition.

Different elements, such as zinc and tin were later added to U.S. copper coins to cut resource costs.

By 1982, the average U.S. penny contained just 2.5% copper.

According to one study, copper-based fungicides have been used to maintain vineyards, keeping the plants in top shape.

The video drew in many viewers who shared their thoughts in the comment section.

“Not me instantly getting up to put pennies in my Valentine’s Day flowers,” one wrote.

“My aunt owns a flower shop and she told me how she keeps the flowers fresh for weeks is adding filtered water, and a teaspoon of bleach,” another added.

“If not then filtered water and at least one or two pennies.”

“I’ve got the pennies,” a third commented. “Just need the flowers now.”
