Keep these festive plants looking healthy and beautiful throughout the season and beyond.

Poinsettias wrapped in shiny foil brighten the holidays with their red, creamy white, pink, or bicolor blooms. Some have flowers spray-painted in colors like blue and purple and glitter-bombed for some extra sparkle. But the colorful parts of this plant aren't actually flowers. They're bracts, or modified leaves (the true flowers are the small green or yellow parts in the center of the bracts). While spray-painted poinsettias don't usually last as long as the natural ones, these plants all do best with a little TLC. It's especially important to avoid the poinsettia mistakes that people often make. We will show you how, and then these plants will reward you with their festive colors well into the New Year.

1. Exposure to the freezing cold.

Poinsettias are grown in greenhouses to color up in time for the holidays. Then they're shipped off to sell. When we take a pampered plant from a warm store through a cold parking lot to the car, it can start to lose its leaves from the temperature shock. Protect your plant with a bag or some paper if it's going to be outside in the cold for more than a couple of minutes. 

2. Keeping your plant in a room that's too hot or too cold.

Indoor temperatures on the cooler side are fine, says Gary Vollmer, poinsettia product manager for Selecta One. "While outside winter temps will kill a poinsettia, indoor temperatures from 55°F to 75°F are fine." Keep your plants out of cold drafts from doors and windows and away from the heat from vents, radiators, and fireplaces.

3. Not providing the right amount of light.

"Poinsettias in the home are living plants and need some light to thrive," Vollmer says. "Keeping the plant in a bright location will do wonders to keep it going." However, poinsettias can burn in direct sunlight, so give them a brightly lit spot where the sun can't shine right on them.

4. Overwatering your poinsettia.

Pots without drainage holes can leave poinsettia roots sitting in water. This can make the leaves turn yellow and drop, or the roots can rot and the entire plant can die. Make a few holes in your container, or move your plant into a pot that has drainage holes. If you keep your plant in a saucer or a decorative pot sleeve, make sure to pour out any excess water, says Harvey Lang Ph.D., senior technical lead for Syngenta Flowers North America. You could also punch a few holes in the bottom of the pot sleeve and use a waterproof saucer or tray underneath to protect your tabletops.

5. Forgetting to water.

This can be as harmful as overwatering, so don't let your poinsettia dry out. Water when the pot feels lightweight, the plant becomes top-heavy, or the soil feels dry to the touch, says Vollmer. The soil should stay moist but not soggy most of the time.

6. Fertilizing at the wrong time.

There's no need to feed your plants while they're blooming, says Barbara Pierson, nursery manager for White Flower Farm. Poinsettia colors often start to fade by February. If you want to keep your plant for its green leaves, or to coax it to rebloom, wait until May to start fertilizing. Follow the directions on your product label.

7. Feeling stressed about keeping poinsettias alive after the holidays.

To look lush and colorful when you buy them, poinsettias are grown in greenhouses with just the right lighting, temperatures, and care, says Lang of Syngenta Flowers. That's why it's challenging to get your plant to bloom again. Save yourself the hassle and just compost your tired plant after the holidays. Then, treat yourself to a fresh poinsettia next year.
