Extending the Life of Cut Flowers

March 10, 2017

The care and handling of fresh flowers depends on how they are to be displayed. The three most common ways to display are: simple cut flowers; cut flowers in a vase; and an arrangement of cut flowers in floral foam.

Fresh Cut Flowers Care

Let’s start with cut flowers just purchased. Keep them out of extreme temperatures when bringing them home. Hopefully, the flowers you bought were properly processed along the way from the farm to you. If you’re going to display your flowers in a vase, use  a vase that has been cleaned with soap and water, then rinsed with bleach. Re-cut all the flowers to your preferred length, removing any foliage that would be below the water line. Cutting at an angle or under running water is a matter of your preference; there’s no proof that these methods make any difference.

Taking Care of Fresh Cut Flowers in a Vase

Bath temperature water works best for your vase, since cold water is slower for flowers to drink, as opposed to warm water, which is lighter and easier for flowers to absorb. Commercial cut floral food is best, especially when used as directed. Too little will do nothing, and too much can shorten the life of the flower. The three properties of preservatives are glucose (sugar), an anti-bacterial (bleach), and pH lowering agent (lemon juice, lime juice, or vinegar).

This means that if you don’t have a floral-quality preservative, you can use (1) a capful of bleach, (2) lemon or lime non-diet soda, plus (3) a tablespoon of sugar.  (I don’t believe aspirin or copper pennies do anything!) Keep the vase you need out of direct sun and, if possible, in a cool place.

Your cut flowers should be re-cut on their second or third day. Remove the flowers carefully, so as not to change the design. A large rubber band or tie can keep them together until you re-cut the stems; remove any flowers that have passed their prime. Clean the vase and refill with warm water two-thirds full, plus more preservative. Remove the tie and replace the flowers in the vase.

How to Care for Flowers in Floral Foam

A pre-designed arrangement in floral foam gives you little to do. You can’t re-cut the stems—but you must add water. It’s best to add water in the kitchen on a drain board, causing no furniture damage if it spills. If that’s not possible, add a few ice cubes to the back, directly on the foam. It’s hard to know if the foam has enough water, but you can always tip the container; if water drips out, it’s well saturated. If flowers growing in the garden are cut for in-home use, they should be cut early in the day as possible before they are stressed from the heat of the sun.
