Introduction to Poinsettias
Poinsettias (Euphorbia pulcherrima) are the quintessential holiday plant, beloved worldwide for their spectacular, star-shaped bracts in vibrant shades of red, white, pink, and bi-color. Native to Mexico, where they grow as large shrubs and small trees, Poinsettias have been cultivated for centuries and were considered sacred by the Aztecs. Today, they are the best-selling potted plant in the United States, with millions sold each holiday season. While often treated as disposable seasonal decorations, Poinsettias can actually be kept alive year-round and even encouraged to rebloom the following holiday season with the right care.
Light Requirements
Poinsettias need bright, indirect light for at least 6 hours daily. A south- or east-facing window is ideal. Avoid direct harsh sunlight, which fades the colorful bracts. Adequate light is essential for maintaining the vibrant color of the bracts and keeping the plant healthy throughout the holiday season.
Watering
Water when the top inch of soil feels dry. Poinsettias are sensitive to both overwatering (which causes root rot and leaf drop) and underwatering (which causes wilting and leaf drop). Always remove the decorative foil wrapper before watering to ensure proper drainage — standing water in the foil is a very common cause of root rot. Water thoroughly and allow excess to drain completely.
Humidity & Temperature
Poinsettias prefer temperatures between 65–75°F (18–24°C) and moderate humidity. They are very sensitive to cold drafts, temperatures below 50°F, and sudden temperature changes — all of which cause rapid leaf drop. Keep away from cold windows, exterior doors, and air conditioning vents.
Soil & Potting
Use a well-draining potting mix with added perlite. Poinsettias prefer slightly acidic soil (pH 5.5–6.5). If repotting, choose a pot only slightly larger than the root ball and ensure excellent drainage.
Fertilizing
Do not fertilize during the blooming period. After the bracts fade, begin feeding every 2–4 weeks with a balanced liquid fertilizer to support new growth.
Encouraging Reblooming
Getting a Poinsettia to rebloom requires a strict dark period starting in early October. Place the plant in complete darkness for 14 hours per night (cover with a box or place in a dark closet) and bright light for 10 hours during the day. Continue this for 8–10 weeks. By Thanksgiving or early December, colorful bracts should begin to develop. This requires commitment but is very rewarding!
Toxicity
⚠️ Poinsettias are mildly toxic to pets and humans if ingested. The milky sap can also cause skin irritation. Keep out of reach of children and animals.

Common Problems & Solutions
Leaf drop: Cold drafts, temperature stress, or overwatering — keep in a warm, draft-free spot and check soil moisture. Wilting: Underwatering or root rot — check soil moisture and drainage. Fading bracts: Insufficient light — move to a brighter location. No reblooming: Insufficient dark period — ensure 14 hours of complete darkness nightly for 8–10 weeks.
