Peace Lily is one of the most popular houseplants — easy to care for and well suited to indoor life. Here's a quick, no-nonsense care guide: light, watering rhythm, humidity, and whether it's safe around pets.
⛔ Toxic to cats & dogs
Peace Lily is toxic to cats and dogs (ASPCA): Insoluble calcium oxalates — oral irritation, drooling, vomiting (distinct from the kidney toxicity of true lilies). Keep it well out of reach of pets and small children, and contact your vet or a pet poison helpline if it's chewed or swallowed.
Peace Lily care at a glance
☀️ Light
Tolerates low light — a few feet from a north- or east-facing window, or a well-lit room without direct sun. Growth slows in low light, so it drinks less; water less often too.
💧 Watering
As a rule of thumb, water about every 5 days — but always let the top 2–3 cm (1 inch) of soil dry out first. Use the calculator below to fine-tune for your light, season, pot size and humidity. Remember: overwatering, not underwatering, is the most common way houseplants die.
💨 Humidity
Loves higher humidity (50%+). Group it with other plants, sit it on a pebble tray, or run a small humidifier, and keep it away from heating vents.
🌱 Difficulty
Beginner-friendly — hard to kill and forgiving of the occasional missed watering. A great first houseplant.
