This is a question we get asked a lot. Poinsettias are popular for adding a festive touch for the holidays, but they can quickly disappoint if they are not properly cared for. To keep them looking their best, follow these simple rules:
#1. Don't freeze it. Take it straight home (or to another room temperature location) after you buy it. Leaving it in your car while you run more errands could be the kiss of death. Keep poinsettias away from windows or cold drafty spots.
#2. Don't torch it. Keep poinsettias away from heat sources like fireplaces, heating vents and candles.
#3. Don't drown it. Ok people, this is the number one cause of most plant deaths! Only water when the soil is dry to the touch. This means you have to actually touch the soil to check. Small plants will dry out quickly and may need daily watering, while bigger plants need less frequent watering. While you're at it, TAKE IT OUT OF THE FOIL COVER to water. It's helpful to move your plant(s) to a sink or tub for the job. The foil covers are pretty and decorative, but don't allow for proper drainage. If water has accumulated in the foil cover, dump it out.
Keeping these rules in mind, poinsettias can easily last through the holidays and can even be coaxed into blooming yearly (for you patient/ adventurous people).
