Flowers normally include a packet of commercial flower preservatives, which you don’t want to discard. Properly caring for fresh-cut flowers you receive from the florist or buy at the market will extend the life of the arrangement by a number of days. Overall, the techniques for extending the life of cut flowers from the garden and those delivered by the florist or purchased from the market are similar.
Step Two
Cut the flower stem from the plant and immediately place in the water. Remove all foliage from the stem that falls below the water line. If the foliage decays in the water, it will accelerate the decay of the flowers.
Step Three
Let the flower stems soak in the water for about two hours prior to making an arrangement.
Step Four
Fill the vase with warm water and add some commercial flower preservatives to the water, following the instructions on the manufacture's label. Use this vase and water for your arrangement.
Step Five
Fresh Cut Flowers From the Florist or Market - Empty and refill the vase with warm water and commercial flower preservative, following the instructions on the manufacturer's label.
Step Six
Snip off one-half to one inch of each flower's stem, cutting it at an angle. Return the flowers to the original vase, with the fresh water and preservatives. Foliage below the waterline should be removed.
Step Seven
All Cut Flowers - Place the flowers in a location out of the direct sunlight and away from heat generating appliances and lights. Keep out of drafts.
Step Eight
Replace the water with fresh warm water and preservatives every three days.
