Poinsettia Pot Culture

Euphorbia pulcherrima Willd. ex Klotzsch

Growing poinsettia as a pot culture requires strict photoperiodic control for flowering induction and plant habit management to achieve a compact form.

In the reference 168 varieties crop Poinsettia, where this is mentioned in the description.

Commercial poinsettia pot culture is based on the management of physiological processes in this short-day plant. Strict twelve- to thirteen-hour periods of complete darkness are necessary for successful flowering induction and bract coloration. The species' natural tendency for vigorous growth is corrected by using cultivars with pronounced apical dominance, pinching of lateral shoots, and the use of growth regulators that limit plant height to thirty to sixty centimeters.

The poinsettia root system is characterized by high sensitivity to waterlogging, which necessitates the use of well-drained substrates and a strict irrigation regime. The plant's production cycle is rigidly tied to the seasonal shortening of the day length. If temperature or lighting conditions are disrupted during transport and storage, the crop is prone to premature leaf drop, and the presence of milky sap must be taken into account during care.
