Poinsettia Care Guide

Euphorbia pulcherrima

Also known as: Christmas Star, Christmas Flower

Watering

Summer

Every 8 days

Winter

Every 10 days

Water when the top cm feels dry. These plants like consistency but not soggy roots.

Light

Bright indirect

Near a window but no direct rays hitting the leaves

Humidity

40-60%

Average home humidity is fine.

Pet & Child Safety

Mildly toxic - may cause irritation

Harmful to: cats, dogs

Pot & Soil

Keep in original pot through flowering. Use well-draining mix when repotting.

Pot-size watering

The 8-10 day range is a starting point. A 5cm pot usually dries faster than a 22cm pot; use the dry-down check as the final signal, not the calendar alone.

Balanced root room

This plant does best with a pot just larger than the root ball. Too much spare wet soil can make watering harder to judge.

Soil refresh

Top up or loosen the surface yearly, and plan a fuller soil refresh when the mix compacts, smells sour, drains poorly, or the plant needs repotting.

💡

Good to Know

The "red flowers" are actually colored leaves. Needs 14+ hours of darkness to rebloom.
