Poinsettias will thrive for years if you add one common spice to the soil now

A poinsettia, known for its bright red leaves, has been a festive favourite in UK homes for decades.

Many people buy new ones each year, but with some basic care tips, you could keep yours for more than just the festive period.

Elise Harlock, of , said: “Cinnamon can act as a fungicide and prevent mould and fungus from forming on the soil. This is especially helpful if you notice your soil stays damp for too long.

“Half a teaspoon of cinnamon, sprinkled evenly across the soil, is enough to keep the soil healthy while still being safe for the plant.”

Cinnamon can also be mixed into the topsoil of the plant to ensure even distribution.

Elise explained how gardeners can add more cinnamon if watering washes the spice away, but it’s important to avoid overdoing it as this can affect the soil’s pH balance.

When poinsettias are placed in sunlight, their gorgeous red leaves turn green.

According to the flower expert, a “daylight diet” is effective in getting the plant’s signature colour back.

Elise explained: “The key to this is darkness. Poinsettias need 10 to 14 hours of total blackout per day for at least a couple of weeks to return to their glorious red hue.

“You can do this by covering them with a cardboard box or placing them in a cupboard. Do this at night and put it in bright light during the day.”

If you have a healthy green poinsettia, dark spells can be introduced from October.

Temperature is also an important part of maintaining a poinsettia, and they thrive in temperatures between 15C and 18C.

Elise continued: “You should check the pot every day and keep the soil moist too. If the soil is dry to the touch, it needs watering.

“Poour lukewarm water in small amounts at a time to avoid drenching the plant and avoid splashing the leaves.

“Ensure you have adequate drainage in the pot so the roots don’t rot.”

Following all of these tips will help to ensure your poinsettia lasts for years.
