Watering. Water when the top inch of soil feels dry. Avoid letting the plant sit in water to prevent root rot. Reduce watering in cooler months.
Fertilizing. Feed poinsettias every 2-3 weeks during the growing season (spring and summer) with a balanced, water-soluble fertilizer. Reduce feeding in fall and winter when the plant is resting.
Poinsettias are moderately easy to care for. They need bright, indirect light and prefer temperatures between 18-24°C (65-75°F). Avoid overwatering; let the soil dry slightly between waterings. They can be sensitive to cold drafts and sudden temperature changes.
