Frequently asked questions about Peace Lily care
How often should you water a Peace Lily?
When the leaves begin to droop, roughly weekly. Test by pushing a finger about 2–3cm into the soil — if it is dry, water thoroughly until it drains from the bottom; if still damp, wait. Water less in autumn and winter.
What light does a Peace Lily need?
A Peace Lily wants low to medium indirect light, roughly 200–2,500 lux. Match that to the right window and distance, and avoid harsh, prolonged direct sun unless the care notes say otherwise.
Is the Peace Lily toxic to cats and dogs?
Yes. The Peace Lily is toxic to cats and dogs. It contains irritant compounds that can cause drooling, mouth and throat irritation, vomiting and loss of appetite if chewed. Keep it out of reach and contact your vet if a pet ingests any part of it.
How fast does a Peace Lily grow?
Moderate; blooms on and off with enough light. Growth concentrates in spring and summer and slows or stops in the darker months, so judge progress over a full season rather than week to week.
What music helps a Peace Lily grow?
Music tuned to 432 Hz at 44–60 BPM is the science-matched choice — PlantParentPlaylist's White Flag playlist is composed for it. Research by Pagano & Del Prete (Italian National Research Council, 2024) found the 400–800 Hz range promotes stomatal opening and nutrient absorption. Play it 2–3 hours a day.
What Hz frequency is best for a Peace Lily?
432 Hz is the primary tuning for the White Flag playlist. The broader 400–800 Hz band is the range peer-reviewed studies most consistently link to stomatal activity — how plants breathe and take up nutrients.
Why are my Peace Lily leaves turning yellow?
Yellowing is most often caused by overwatering or, in older lower leaves, natural aging. To fix it, let the top of the soil dry between waterings and remove spent leaves at the base.
How do I propagate a Peace Lily?
Division of the root clump when repotting. Propagate in spring or summer when the plant is actively growing for the fastest, most reliable results.
Does the Peace Lily purify the air?
Included in NASA's 1989 Clean Air Study, which confirmed it removes volatile organic compounds such as formaldehyde and benzene from indoor air. It removes formaldehyde, benzene, trichloroethylene and ammonia.
Where can I buy a Peace Lily?
You can find a Peace Lily at most garden centers, nurseries and big-box stores, usually for $10–$30 depending on size. Larger, mature or variegated specimens cost more, and online plant shops and specialist growers carry rarer forms.
