Appointment culture
Appointment culture is a term used in horticulture . This means the cultivation of fruit or flowers in order to obtain ripe fruit bodies / blossoms on the desired date.
Appointment cultures are set to cushion seasonal deficiencies in (regional) availability or because increased demand is predictable, as is the case with poinsettias .
Chrysanthemums as a typical ornamental plant are another example: The hardy sunflower , which actually only blooms from the end of October, allows for an appointment culture in mid-September when it darkens in August.
The cultivation of future crops is realized with the help of the following means:
- Cooling: Here, for example, preserved offspring ( frigo plants ) of the strawberry are only taken out of the artificial winter in summer - and thus stimulated to bloom - in order to be able to harvest them in autumn.
- Darkening : Here, the subjective day length of the plants is shortened in greenhouses and the desired flowering time is achieved.
