Peace Lily (Spathiphyllum) Reblooming: Watering by Weight and Fertilizing

Pam's two large peace lilies bloomed at purchase (funeral), then stopped. Blooms now tiny or absent. Asks care for rebloom and if white "foliage" (spathes) return to size.

Peace Lilies Bloom Continuously With Proper Care

They don't "complete a life cycle" — they're perennial bloomers.

Two Fixes

1. Water by weight: Saucer under pot. Water thoroughly, let sit 5–10 min, pour off excess. Lift pot — should feel heavy. Don't water again until noticeably lighter. Don't let wilt. Frequency: daily (outdoors) to 3–10 days (indoors).
2. Fertilize regularly: Weekly to monthly during growing season. Or top-dress with fresh soil.

Result

Consistent moisture (not soggy) + nutrition = large, white spathes repeatedly. They're heavy feeders in bloom.
