# Poinsettia

*Euphorbia pulcherrima*

Common · Flowering · Moderate · Mild

A flowering plant. Prefers bright indirect light. Wants a substrate that drains steadily. As a species it wants water about every 7 days. Mildly toxic if ingested.

## Poinsettia: how often should you water it?

That’s the interval our references converge on for this species indoors: roughly every 7 days between waterings, adjusted for your light and your season.

### Why we don’t give you a date.

We publish the interval this species usually wants. We don’t publish a date for your plant — nothing here measures it. The interval is a starting point you adjust from what you actually log.

Guidance is curated against general horticultural references including the RHS, the Missouri Botanical Garden Plant Finder, and university extension services. Each field is either published or left empty — never estimated.

## Care cadences

- **Water** — Every ~7 days
- **Fertilize** — Every ~30 days
- **Repot** — Every ~365 days

Not established for this species: clean leaves · mist. We’d rather leave them empty than guess.

### Toxicity

Mild · Toxic to pets
Mildly toxic to cats, dogs, and horses (irritant diterpenoid euphorbol esters and saponin-like compounds in the milky sap) per ASPCA; typically causes only mouth/stomach irritation and occasional vomiting — its reputation as a deadly plant is overstated.
