There are numerous factors that play into determining the duration of flower vase life. Such factors involve the genetic lifespan, growing conditions and post-harvest conditions of the flowers.
Flower development and it’s duration, in connection with climatic conditions and other factors, are different for each flower type. The seed growers determine what the expectations are regarding lifespan after harvest and of course any deviations from the optimum care will lead to a short vase life for the consumer.
Growing conditions, such as light, temperature, relative humidity, fertilization and crop protection have a marked effect on the post-harvest quality of the flower, such as length, shape, color and deviation of stem and flower. These factors, however, do not affect the genetic lifespan expectations.
- Temperature and humidity in particular, determine whether the cut flower will be delivered to the consumer in good condition after the harvest. Higher temperatures promote flower development. Humidity plays an indirect role in the condensation process during multiple and temperature fluctuations and promotes the growth of the fungus Botrytis.
- Lack of hygiene promotes the development of micro-organisms, which can cause water to become turbid and smelly.
- Cut flowers come from all corners of the globe and they are shipped across huge distances. Climate control, good packaging, post-harvest treatment and speed are very important for quality conservation. We must assume that each distribution day diminishes the vase life to some degree.
- Using the most suitable post-harvest treatment for each flower type is one of the measures needed to get the flowers through the distribution chain intact. Essentially, these products replace the mother plant and all the required raw materials that make the natural development of the stem, leaf, and flower possible, as if they were still on the intact plant.
