VASILE’S TIPS FOR KEEPING YOUR POINSETTIA HEALTHY
Keep plants protected from draughts and strong sunlight, so avoid window-sills. Poinsettias like it warmer (but not hot) during the day and cooler at night.
Keep humidity down - between 50% and 80%, otherwise they become more susceptible to disease.
Don’t over-water. Check your plant regularly - to start with, take it out of the pot to monitor moisture content. After a while you will know by the weight. Keep the top centimetre or so dry to avoid any disease, and keep the rest moist to the touch but not soggy. The plant will drop its leaves if it is too dry or too wet!
Feed regularly with an all-round fertiliser. Pot the poinsettia after Christmas to allow it to re-bloom next year.
Continue watering and feeding until the end of March, then reduce this gradually so that the plant can go dormant. Place in a cool environment.
Cut the plant back to about 8-10cm after a few weeks. Repot into a larger container, using a compost mix of three parts John Innes No 3 mix to one part grit.
Put it outside, somewhere light but cool, once the risk of temperatures lower than 13C has past.
Water and feed regularly from here on. Increase watering and move the plant into a warmer spot (18-20 degrees C) in early summer (mid-end May).
In autumn, the plant needs dark nights to allow it to colour up and flower, so from mid-autumn place in a dark room between 5pm and 8am, protecting it from artificial light sources.
