Euphorbia pulcherrima

 

Poinsettia

Poinsettia are widely grown indoors over Christmas for their brightly coloured bracts. They are often discarded once the leaves have fallen but with a little care, you can keep them all year and the bracts will colour up again the following year. They need bright, but filtered light, away from strong sun and draughts and a minimum temperature of 13-15°C (55-59°F).

Euphorbia pulcherrima

Poinsettia are widely grown indoors over Christmas for their brightly coloured bracts. They are often discarded once the leaves have fallen but with a little care, you can keep them all year and the bracts will colour up again the following year. They need bright, but filtered light, away from strong sun and draughts and a minimum temperature of 13-15°C (55-59°F).


Flowering

From Early Winter TO Mid Winter

Flowering and bract colouring is initiated by short winter day-length, occurring naturally in early to mid-winter. So from late autumn onwards, plants should be put in a dark room after twelve hours of daylight and protected from artificial light sources. Plants need a constant temperature of around 18°C (55°F) to colour up well, so make sure they do not get too cold.

 

Propagation by cuttings

From Late Spring TO Late Spring

Poinsettias can be propagated by softwood cuttings in late spring, making sure you wear gloves, as the milky sap can be an irritant. Use Bio-rooter.

 

To get a poinsettia to bloom a second year

From Late Spring TO Late Autumn

When the leaves have fallen cut back the stems to leave stumps 4 inches high. The compost should be kept almost dry and the pot placed in a mild, shady position. In late spring, water and repot the plant replacing the compost with three parts John Innes No 3 to one part grit. Continue watering and shoots will soon appear. Feed regularly and remove some of the new growth to leave 4 or 5 strong stems. The prunings can be used as cuttings. From early autumn, careful light control is essential. Cover with a black polythene bag from early evening to the next morning. Total darkness for 14 hours. Continue this routine for 8 weeks then treat normally.
