Poinsettia Care Guide: Keeping Your Holiday Plant Thriving

Myths and Facts

Poinsettias are not poisonous—an Ohio State University study debunked this in 1975. The sap may irritate eyes, but the plant is non-toxic.

The showy red, pink, or white "flowers" are actually bracts (modified leaves). The true flowers are the yellow pouch-like structures in the center.

Immediate Care After Purchase

• Protect from freezing—even 30 seconds below 32°F ruins the plant. Warm the car before transport.
• Remove foil wrapper or poke drainage holes.
• Keep cool (70°F), bright (near a window), and slightly moist—never soggy.

Ongoing Indoor Care

The biggest reason poinsettias decline indoors is letting them get too dry. Check for drafts from heating vents or cold windows. Don't let them wilt, but avoid waterlogging. No fertilizer is needed while indoors.

Reblooming for Next Year

If you want to keep it:

• After bracts fade, trim back and repot into a larger container by March.
• Pinch growing tips monthly to keep compact.
• By summer, move to a large pot (24–30 inches) with good soil.
• From October 1, give 14 hours of total darkness each night and 10 hours of bright daylight to trigger flowering.

Honestly, it's usually easier to buy new plants each December.
