Light

Poinsettias like a lot of light, preferably sunlight. This can be an issue especially since they bloom during the winter.

If they don’t get it, you’ll likely see them last only a fraction as long as they should. In dim locations, they might only be around for a few weeks, which is such a waste given that they can last much longer.

As such, it’s important to plan where you want to position it to get sufficient sunlight exposure.

Being a tropical plant, it enjoys a south-facing location, where it’s likely to get the most sun during the day.

But, it can likewise do well near east or west-facing windows which receive both direct and indirect sunlight.

Temperature & Humidity

Being native to the tropical regions of Central America and Mexico, poinsettias are hardy in USDA zones 10 to 12.

This is why they enjoy temperatures ranging from 65 to 75 degrees. They’re likewise able to tolerate a slight drop in the mercury come night time to about 60 degrees without experiencing any unpleasant effects.

But, once you go below that, they become more sensitive to temperature. The same is true with cold drafts. Thus, it’s a good idea to keep them away from areas where the wind can funnel through objects around your home to them.

Should this happen, it’s a good idea to find ways to increase the humidity in your home. You can do so with a humidifier, grouping them plants together or placing their pots over stone water baths.

It’s likewise a good idea to keep them away from any heat sources like heaters and even your fireplace since the heat that radiates from these objects will cause them to dry up quickly as well.

If you notice this happening, make sure to water them more frequently. But, not to the point where you overdo it.

Place your poinsettias in well-draining potting soil that’s slightly acidic (pH levels between 5.5 and 6.5).

If you live in an area where the outdoor daytime and nighttime temperatures are warm enough, you can likewise transplant them into the garden.

Fertilizing

The most important thing to remember when it comes to fertilizing your poinsettias is to NEVER do so when they’re blooming. Instead, wait until the holiday season is over to do so.

This is where they become high maintenance.

Switching between the 2 locations during day and night is a hassle. And, you’ll need to do it for 2 or so months, which is the reason most people just buy their poinsettias from the store.

Of course, make sure that both locations are warm and humid enough to keep it happy. Both are likewise important if you want to see your poinsettias bloom at their best.
