MANHATTAN, Kan. — Kansas State University horticulture expert Ward Upham said it’s important to let the light shine on poinsettias, often a favorite flower for the fall and winter months.
“Place your poinsettias in a sunny window or brightest area of the room,” Upham said, “but don’t let it touch the cold window panes.”
If windows become drafty at night, it is best to remove poinsettias or draw drapes to avoid cold damage.
For the best bloom results, Upham suggests keeping poinsettias at temperatures between 65 degrees Fahrenheith – 75 F during the day, and 60-65 F at night. He said blooms won’t last as long at temperatures higher than 75 F; root rot may occur at temperatures lower than 60 F.
Poinsettias are also quite finicky about soil moisture conditions. Upham recommends checking soil moisture daily by sticking your finger in the soil, about one-half inch deep.
“If it is dry to this depth, the plant needs water,” he said. “When it becomes dry to the touch, water the plant with lukewarm water until some water runs out of the drainage hole, then discard the drainage water.”
Following the temperature and soil moisture guidelines should keep poinsettias in top shape during the holiday season, he said.
