Light requirements in detail
Peace Lily prefers medium indirect (1000–10000 lux) . Tolerates low light but flowers more reliably in bright indirect; direct sun scorches leaves
A spot 1–2 meters from a bright east or south-facing window usually fits this range. Direct afternoon sun through unfiltered glass can scorch leaves; sheer curtains help diffuse it.
Watering in detail
Water Peace Lily every 7– 10 days during the growing season, allowing Top 2cm of soil to dry between waterings. Reduce frequency in winter when growth slows.
Consistent moisture matters here — long dry spells will show up as crispy leaf edges.
