Cutting Your Flowers
Re-cut the Stems
Condition Your Flowers
Change the Water
It's best to cut flowers in your garden in the morning before the dew has dried, or in the early evening. Using stem-cutting shears or sharp pruners, snip above a node or dormant bud to spur new blooms. Then put stems in a pail of lukewarm water as you cut them.
Here's the trick - once your flowers are cut, re-cut the stems on a slant, under water to eliminate air bubbles that block water uptake. Certain types of flowers (including celosia, sunflower and zinnia) benefit from scalding the stem ends in boiling water for 20 seconds, or over a candle flame, to stop nutrient-rich sap from oozing.
Condition flowers several hours before arranging. Rest stems in lukewarm water in a cool, dark place so they can absorb water. To prevent decay, remove bruised leaves and foliage below the water line.
Arrange conditioned flowers in a vase of warm water. To slow aging, place the vase in a well-ventilated, cool place (as low as 38° F) and be sure not to store flowers near unsealed fruits and vegetables like tomatoes and apples, which produce ethylene, a gas that hastens ripening or, in the case of flowers, aging.
To prolong the vase-life of your cut flowers, add Miracle-Gro® for Fresh Cut Flowers. You'll want to change the water in your vase every couple of days, adding more Miracle-Gro® for Fresh Cut Flowers each time. In the case of a mixed bouquet, some of the flowers may give off sap that is toxic to other varieties in the vase, shortening their vase life. You'll avoid this by frequently refreshing your flowers' water.
