How do I keep a poinsettia healthy through the holidays?
The Short Answer
Poinsettias thrive with bright indirect light, temperatures around 65 to 70 degrees, and careful watering that never leaves them soggy. Protect them from cold drafts on the way home in Michigan winter, and a healthy plant will hold its color for weeks or even months.

Bringing your poinsettia home safely
Poinsettias are tropical plants and genuinely hate the cold, so the trip from the shop to your car in a Michigan December can shock them. Ask for a protective sleeve and get the plant into a warm car quickly, avoiding long stops where it sits in freezing temperatures. Even a few minutes of cold exposure can cause leaf drop days later. Once home, unwrap the plant so air can circulate and place it in its display spot. Handling the first hour well sets your poinsettia up to look vibrant all season.
Light, temperature, and placement
Poinsettias want bright, indirect light, so a spot near a sunny window without direct scorching sun is ideal. They prefer daytime temperatures around 65 to 70 degrees and cooler, but not cold, nights. Keep them away from cold drafts, exterior doors, and heat sources like radiators and fireplaces, all of which stress the plant and shorten its display life. Consistent, comfortable room conditions keep the colorful bracts crisp. If leaves start dropping, temperature swings or drafts are usually the culprit.
Watering without overdoing it
The most common way to lose a poinsettia is overwatering. Water only when the soil surface feels dry to the touch, then water thoroughly until it drains from the bottom. Always empty the decorative foil or saucer so the roots never sit in standing water, which causes root rot. Poke a few holes in foil wrap if it traps water. Underwatering shows as wilting that perks back up after a drink, while overwatering leads to yellowing leaves that fall. When in doubt, let it dry slightly rather than keeping it wet.
