Poinsettia Reblooming: The 10-Week Strict Schedule

It's Possible But Demanding

Harriet's poinsettia sprouted green leaves after months of neglect. To rebloom for Christmas:

Year-Round Schedule

1. Jan–Mar: Houseplant care, sunny window, barely moist, fertilize biweekly.
2. Late Mar/Early Apr: Prune to 6–8 inches. Repot.
3. Summer: Outdoors, 6–8 hrs direct sun, weekly fertilizer. Prune ⅓ in late July.
4. Early Fall: Bring in before 50°F nights. Sunny window, continue care.
5. Oct 1–Thanksgiving: TOTAL DARKNESS 5 PM–8 AM (closet/black box). 65–70°F nights, 70–80°F days. No missed days!
6. Color shows: Stop fertilizing. Display.

Dormant Option

If too much work, let dry, drop leaves, store cool (55–60°F) dark until April, then restart.
