Poinsettias are very cheery plants, the quintessential Christmas plant known for the bright red flowers juxtaposed by stunningly rich green leaves. What most people don’t realize though is that you can grow these all year round even after they start to fade. All you have to do is put forth a little bit of care and you can keep the plants growing all year inside, and make sure they produce bright red shades there so famous for year after year.

What to do with a poinsettia after the red leaves turn green

Step 1

In order to avoid the disappointments that typically accompanies the second year of owning a poinsettia, you want to start pruning the plant back hard in April to no more than 10cm.

Step 2

Next place the plant in a room where it is exposed to continual temperature ideally around 13 degrees Celsius. You may need to repot your poinsettia as they are usually grown in small pots for the size of the plant. Grow it in a light, cool place for the remainder of the summer with an ideal temperature between 15 degrees Celsius and 18 degrees Celsius, no more.

Step 3

The flowering and subsequent colouring is actually stimulated by the shorter day length of winter which naturally takes place in December and January. But you can simulate this in November by putting your plant in a dark room once it has been exposed to 12 hours of daylight or even put a cardboard box over ti to control how much daylight it receives. Be sure to protect the plant against artificial light sources. They need 12-14 hours of darkness each day, get this wrong and nothing else matters, you won’t get the red leaves.

The plant will need a regular temperature that hovers around 18° C in order to produce the bright Reds that everyone loves so you have to be sure that the plants never have an opportunity to get too cold, even a cold breeze can cause them to quickly drop there leaves. Rest assured commercially grown products are typically treated with chemicals to keep the colour vibrant but just like your natural soil in your garden, the plant will revert back to its original colour the following season so by following these steps you can ensure you don’t have that issue with which to contend and instead you have the quintessential Christmas plant year after year and our course they get bigger and bigger too.
