🔍 Light Optimization Tips
- For maximum flowering: Bright, indirect light produces most blooms
- For air purification: Any light level maintains toxin removal ability
- Office placement: 4-6 feet from fluorescent lights works perfectly
- Avoid direct sun: Causes leaf scorch and brown tips
- Seasonal adjustments: Move closer to windows in winter
Light Troubleshooting:
- No flowers + green foliage: Increase light gradually
- Brown leaf tips: Too much direct sunlight
- Pale, small leaves: Insufficient light
- Healthy growth, no blooms: Plant may be too young (needs 1+ years)
💧 The Smart Watering System
Peace Lilies have a built-in watering indicator that makes them perfect for beginners - they literally tell you when they're thirsty by drooping their leaves!
The Peace Lily Watering Method:
- Watch for the droop: Leaves will droop noticeably when water is needed
- Water thoroughly: Saturate soil until water drains from bottom
- Allow recovery: Leaves perk up within 2-4 hours after watering
- Wait for next droop: Usually 5-10 days depending on conditions
💡 Pro Watering Tips
- Perfect timing: Water when leaves first start to droop
- Water quality: Filtered or distilled water prevents brown tips
- Drainage essential: Never let plants sit in standing water
- Humidity boost: Place on pebble tray for extra moisture
- Bottom watering: Works excellently - place pot in water tray for 30 minutes
