Flowers for Cutting from Seed
by Diane Linsley
For some people, the whole point of gardening is to grow cut flowers, either for their own enjoyment or for a business. In general, any flower with a long stem and a long vase life can be used. But some flowers are better for cutting than others. To start with, here are some tips for cutting flowers.
Extending the Vase Life of Cut Flowers
1. Cut the flowers in the early morning, using sharp, clean garden shears. Don't use scissors, which may crush the stems. Bring a plastic bucket or a pitcher of water to put the flowers in as soon as they are cut.
2. Recut the stems right before putting them in the vase. Cut at a 45 degree angle. Remove any foliage that is below the level of the water.
3. Fill the vase with lukewarm water, which is easier for flowers to absorb. It should be between 100 and 110 degrees. You can add a commercial preservative to the water, or make your own using 1 quart of water with 1 teaspoon bleach, 1 teaspoon sugar, and 2 teaspoons lemon juice. This recipe is from the Brooklyn Botanic Garden.
4. Keep flower arrangements away from fruit, which produces ethylene gas that shortens the vase life of cut flowers.
