The three biggest mistakes that ruin poinsettias are: exposing them to cold drafts, overwatering, and keeping them in low light. Avoiding these will keep your plant vibrant all season long.

1. Improper Watering

• Overwatering is the most common problem → leads to root rot and yellowing leaves.
• Underwatering causes wilting and leaf drop.
• Let soil dry completely between waterings; water just until moist, not soggy.
• Misting helps hydrate leaves without affecting soil moisture—especially useful in dry winter homes.

2. Wrong Light Conditions

• Poinsettias need bright, indirect light.
• Direct sunlight shortens bloom life.
• Move plants away from sunny windows during peak brightness.

3. Temperature Extremes

• Ideal temperature: 70–75°F.
• Cold drafts or overly cool rooms signal “winter” to the plant → early bloom loss.
• Heat sources (fireplaces, vents, lamps) dry leaves and soil too quickly → stress and shortened bloom time.

Post-Bloom Care

When bracts fade, prune the plant back to about 4 inches, place it in a sunny window, and allow it to regrow. New leaves appear in a few weeks.
