POST HARVEST TREATMENT
It is best to let all flowers have a period of rest before arranging.
Ensure that all foliage is removed from the stems below the water level.
Separate “dirty” flowers such as sunflowers, daffodils and zinnias when initially harvested or after re-cutting stems and allow the sap to run out before adding back into arrangements or bouquets. The sap will dirty the water and allow bacteria to grow.
Some flowers require unique treatments to sustain vase life such as dipping in boiling water, burning/searing – Honeywort and Poppy.
GOOD TIME NOT A LONG TIME
Despite their stunning beauty and even when provided the best care, some cut flowers only last a few days in the vase. These flowers include:
Woody stems such as lilac, apple blossoms. forsythia and mock orange need more encouragement to uptake water than typical flower stems. Two techniques to prolong vase life are:
Cut stem at an angle and then make a one inch cut directly up the stem. Spread the 2 halves apart.
Cut stem and smash ends for an inch or two up the stem with a hammer.
