What to do with poinsettia after Christmas

In all fairness, the UK climate is not exactly ideal for the tropical plant that is poinsettia. But if you choose the right room and environment for your plant then half of the work of keeping it alive is already done.

‘Poinsettias are only really comfortable in damp warmth,’ says Monty. ‘They do not like cool nights, very hot dry rooms or big fluctuations in temperatures, so keep them where there is a constant average temperature, avoiding draughts, cold windows or even very bright spots that can get very hot in the middle of the day.’

And what this gardening expert says is gospel around here, which is why we follow everything from Monty Don’s greenhouse advice to his winter lawn mowing advice. 

Other experts are quick to agree with his tips, including this one.‘After Christmas, you can keep your poinsettia plant alive and healthy by following a few simple steps,’ says Jack Sutcliffe, gardening expert and co-founder of Power Sheds.

How to care for poinsettia

As pointed out by Monty, where you place your poinsettia is crucial. Keeping it indoors is essential as the plant doesn’t like cold weather or temperature fluctuations.

‘Poinsettias are tropical plants and are sensitive to cold temperatures. Keep your poinsettia indoors in a location with bright, indirect light,’ advises Steve Chilton, garden expert at LeisureBench. ‘Avoid placing it near drafts or heating vents. Maintain a comfortable indoor environment to keep your poinsettia healthy.’

Watering

‘Water the plant when the soil feels dry to the touch. Water thoroughly, until the water runs out of the bottom of the pot,’ Jack says.

Monty Don recommends ‘standing the pot in a sink full of water and leaving it to stand for 10 minutes or so before letting the excess water drain from the pot.’

But you can also water it conventionally. Just be careful not to overdo it.

‘Avoid overwatering as excessive moisture can lead to root rot,’ Steve warns.

Feeding

In order to encourage your plant’s health and growth, it’s recommended to treat it to some fertiliser in the spring and summer months.

‘Feed your poinsettia with a balanced, water-soluble fertiliser around once a month during spring and summer,’ Steve says.

Pruning

For your poinsettia to grow those beautiful, vibrant blooms in time for next Christmas, the plant requires a period of dormancy. And to help the plant get that time to recharge and set buds for next season, you will need to prune it and expose it to hours of darkness.

‘To encourage flowering in the next season, in late spring, prune it back, leaving about 15 centimetres of stems,’ says Petar Ivanov, gardening and plant expert at Fantastic Gardeners.

'Keep the plant in a warm environment, and around October, provide 14 hours of darkness daily for about 6 to 8 weeks to stimulate the colourful bract formation.'
