Why Peace Lily Flowers Turn Green and How to Encourage Reblooming

Green Flowers Are Normal Aging

Peace lily (Spathiphyllum) blooms naturally fade from white to green, then brown. This is part of the plant's life cycle, not a sign of disease.

Promote More Flowers

• Cut off spent flowers at the base of the stalk as soon as they lose their appeal. Leaving them signals the plant to stop producing new blooms.
• Provide bright, indirect light—essential for flowering.
• Keep the plant moderately potbound; overpotting encourages root growth at the expense of flowers.

Watering Warning

Peace lilies are not swamp plants. Let the soil surface dry for at least 3 days before watering. Never leave the pot sitting in a water-filled saucer—roots rot quickly.

Quick Checklist

1. Remove green/brown flowers promptly.
2. Place in bright indirect light (no direct sun).
3. Water only when top inch of soil is dry.
4. Avoid oversized pots.

Follow these steps and your peace lily will reward you with repeated flushes of white blooms.
