Poinsettias - Facts & Care

Facts about Poinsettias and how to care for them

Facts
The flower most often associated with December and the holiday season is the poinsettia. Known for its brilliant red, it is now available in a wide variety of colors. The poinsettia is native to southern Mexico where the Aztecs used it in ceremonies, as a medicinal and to make red dye. Secondary to a myth dating back to the early 20th century, it is believed that poinsettias are poisonous. This is NOT true. All parts of the plant have been extensively tested and researchers have found it to be completely nontoxic and safe. Being a member of the Euphorbia family (Euphorbia pulcherrima), it does exude a milky sap to which some people are allergic; therefore, it is still best to keep it out of reach of small children and pets which might be prone to eat it. Poinsettias are not true flowers but bracts. Their flowers are actually bead-like clusters at the center of each leaf bract.

Care
Poinsettias can maintain their color through the winter and into spring if they receive the proper care.

Light:

Relatively low. Bright lights will cause the plant to loose color more quickly, as it will think the season has changed to spring.

Moisture:

Uniform. Too much or too little water will cause the roots to collapse. Water when the soil in the pot begins to feel dry, but do not allow the plant to wilt. Be sure to remove the foil wrap before watering and empty the saucer of any water. Do not allow the plant to sit in water.

Temperature:

Moderate. Temperatures between 60-70 degrees F are best. Placing the plant in a cool room (between 55-60 degrees F) at night will extend the bloom time. Keep out of cold drafts or in areas where there are sudden temperature fluctuations.

Fertilizing:

Do not fertilize while the plant is in the active blooming stage.

Forcing Re-blooming/Recoloring
Poinsettias can be forced to re-bloom in time for the winter holiday season. This is accomplished by subjecting the plant to a complete darkness phase for 12 hours a day for 6 weeks. It is imperative that no light reach it during these 12-hour periods, as any light exposure can diminish its color or prevent it from flowering altogether. (An example would be placing it in a closet that is not opened from 6 pm to 6 am., then removing it during the other 12 hours.) Continue watering during this phase. Do not let the plant dry out. After completing the darkness phase, place it in a moderately lit area to trigger the growth phase and follow care instructions above.
