The poinsettia, or Christmas Star ( Euphorbia pulcherrima ), is a plant native to Mexico that is very popular during the holiday season for its magnificent colored bracts, often red, although they also come in white, pink or two-tone. Contrary to popular belief, it is not its flowers that are colored, but the bracts, which surround its small central yellow flowers.
Making a poinsettia bloom again requires a little patience and precise management of light and growing conditions. Here are the essential steps:
1. After flowering (January to March)
Once the colored bracts (red leaves) fade, gradually reduce watering.
Prune the stems to about 10 cm in height to encourage new growth.
Place the plant in a bright and temperate location (15-18°C).
2. Growth (April to September)
Resume regular watering as soon as new shoots appear.
Repot the plant in well-draining soil if necessary.
Add fertilizer for flowering plants every two weeks to stimulate growth.
Place the poinsettia in a bright location, but without direct sunlight.
3. Prepare for flowering (October to December)
For the colorful bracts to develop, the poinsettia needs a strict cycle of short days:
For 8 to 10 weeks, expose the plant to 14 hours of total darkness each night.
Place the plant in a completely dark room or cover it with cardboard or an opaque bag from 6 p.m. to 8 a.m.
