Cut Flower Powder

[carlton23]

When you buy flowers, a small bag of powder is supplied to feed them in the vase. What is it? When I cut flowers I trim the leaves of for about 8" from the base of the stem and add a teaspoon of sugar to slightly warm water but would like to know what florists use.

I've cut & pasted this article that might be of use to you. It starts with a question & is answered with different tips. Hope it helps

Is a copper penny the right choice to keep cut flowers fresh? Or is the little packet of flower food? An aspirin? What water temperature is best? What is the trick that will triple the lifespan of cut flowers?

Often folk tips are based on good science. Learn about what works and what doesn’t, and why, to keep your cut flowers fresh, here:

Copper Penny, Aspirin, and Other Alternatives to Chemical Flower Food
The little packet of flower food are bactericides that kill the bacteria, yeasts, and fungi.

Here are tips of reaching this same goal without the chemicals:
* Copper is a fungicide and acts to preserve the water from too many yeasts and fungi.
* Aspirin is an acid and helps to kill bacteria overgrowth.
* Add 2 tablespoons lemon juice or vinegar to 1 quart of water. The idea here is the same as with aspirin, since lemon juice and vinegar are acidic.

Other Guidelines To Keep Fresh Flowers Fresh
* Place cut flowers in cold water, not warm! Warm water dehydrates flowers.
* Placing cut flowers in the refrigerator for six hours before arranging them will triple their lifespan.
* Hot water–up to 110-200 F–is recommended to restore very wilted flowers (the hotter water is for the more wilted flowers).
* Except for when you are cooling flowers, when you want cold water to cover the stems of the flowers, there is no need to have the water go higher on the stems then six inches.
* Recut the stems every few days.
* Remove all leaves and foliage below the water line.
